"drain"

The refurbishment of platforms is part of Network Rail’s government funded National Stations Improvement Programme (NSIP ). The five year programme aims to deliver £179 million worth of station improvements to a minimum of 150 medium sized stations in England and Wales.An overarching objective of the programme is to achieve a noticeable improvement to the passenger perception of stations whilst providing value for money in station investments. Part of this remit involves aspects of customer comfort and safety, including ensuring that the control of surface water runoff is efficiently and effectively managed. For this project Murphy Group were commissioned by Network Rail as the main contractor.Clark-Drain has provided a total of 740m length CD 434 linear drainage channel for installation in three of the station‘s platforms to drain the surface water at a maximum rate of 4.6 l/s into silt box traps before discharge into the mains.The silt boxes work by retaining runoff to allow deposited silt to settle to the bottom of the basket before the water is discharged via the outlet pipe connection. The basket is located so that it is easily removed for periodic cleaning. Both the channels and silt boxes are lightweight and designed for easy handling, installation and maintenance. The bodies of the channel are constructed from recycled hard wearing polypropylene to protect them from damage and ensure long lasting durability. A BS EN 1433 Class B125 quick-fit grating with ‘CatchLock’ retention system provides all the strength required for the 12.5 tonne loading it was designed and tested to withstand and perfectly suits high trafficked station platforms.The narrow-slot ‘heel-guard’ design reduces the potential for tripping and slipping and provides a useful safety feature for passengers and rail staff.The weight of each one meter length, at 5kg, made it very easy to install enabling Murphy Group Engineers to lay several lengths in one go for faster levelling and taking 25% less building time  than heavier polymer concrete options. As part of the aesthetic appeal of the platform refurbishment, the CD 434 was specified because of its flexibility to follow the curve of the platform edge, giving uniformity and enhancing the visual appearance when laid to the same contour.In addition, the linear drainage channel was supplied with 450 x 450mm, 600 x 600mm and 750 x 600mm steel recessed covers and frames. These enabled 60 of the stations lighting cable access chambers to be securely covered and in-fi lled with the marble effect paving specified for the station floor as part of an attractive and functional design for the public to enjoy.WHY THE CD 434 WAS CHOSENLightweight – The one meter length channel and grate is lighter, weighing 5kg, compared to traditional concrete products weighing 20kg or more without being detrimental to its strength for EN1433 B125 loading.Reduced manual handling – Lightweight design and simpler, easier and safer installation provides greater emphasis on health and safety, reducing work related injuries.Easy and quick to install – Installing up to four lengths in one go enables faster levelling, taking 25% less time than traditional polymer concrete.Dual Locking – The Catchlock system simplifies locking of the grating yet enables safe and speedy access for maintenance. The optional anti-tamper bolt locking system provides added security against theft, reducing time and cost spent on replacing lost gratings.Anti-slip and narrow slot finish – Reduces the potential for tripping and slipping, helping to improve public safety.100% recycled – ‘Green’ credentials help toward reducing the carbon foot-print and act as a theft deterrent due to having no intrinsic scrap value.Enhanced durability – Carefully designed load transfer structure improves product life span and lowers maintenance and replacement costs.Heat resistant – The polypropylene/nylon properties make the CD 434 channel ideal for hot tarmac installation.

Before there was an open, 4" (100mm) diameter pipe that drained water from the back of this Devon farm house into the yard. Apart from an open pipe, which never looks good on a listed building, when it rained heavily there was water gushing out across the road causing havoc to any cars parked nearby. With the installation of the cast iron cowled conservation vent now the water is deflected downwards and the opening is no longer open to the elements and in eye line. With a choice of 100mm or 125mm spigots this cowled vent has many uses

JT Atkinson, a family owned independent builders' merchant in the North of England, needed a lightweight yet robust drainage solution for their new branch in Stokesley. They required a reliable and durable solution which would be installed quickly, to ensure their 30th branch opened on time.  The branch yard would be a highly trafficked area, so the JT Atkinson team were seeking a drainage solution that could withstand large loads and constant heavy traffic of forklift trucks and articulated lorries.Technodrain is an advanced, linear drainage channel, providing versatility whilst being economic, light and quick to install. Constructed of High Density Polyethylene (HD-PE), it delivers long life with low whole-life cost. Having used Clark-Drain products at their other branch sites, the JT Atkinson team knew first-hand the quality of Clark-Drain’s products and customer service.Designed for surface water management, the versatility of Technodrain enables it to be used across all construction environments as a light, robust, solution for run-off surface design. Technodrain’s size-to-weight ratio maximises its savings in transport and installation costs, and this installation was within the limits set by the HSE manual handling guidelines for a one person lift.Chris Gilbertson, Project Manager for JT Atkinson, says: “We were looking for a quality drainage product which would be easy to install, able to withstand F900 loads, and be long lasting. Technodrain from Clark-Drain is the ideal solution and doesn’t disappoint. Not only does it provide us with the drainage we need at a competitive price, the installation was extremely easy thanks to its lightweight nature.”Technodrain was installed at the Stokesley branch of JT Atkinson in October 2019.WHY THIS PRODUCT WAS CHOSEN Hard wearing – Constructed of High Density Polyethylene (HD-PE), Technodrain delivers long life with low whole-life cost.Easy to install – Tongue and groove joints allow for ease of installation and the connection of multiple channels. Preformed lateral and vertical channel outlets also provide quick and easy connection to discharge pipes.Cost effective – whilst providing a safe environment and a highly efficient system for surface water clearance. BS EN1433:2002 – Load handling performance is rated at 90 tonnes, making it durable with strength to spare in an area used by a range of vehicles from forklift trucks to artic lorries.Hydraulic performance – With maximum through-flow of 8.25 litres per second and a water way area of 372cm2, it has more than enough capacity for JT Atkinson.Bolted locking system – Technodrain features a bolted locking system, with 4 bolts in every 500mm to avoid grating movement.

Ashdown Forest in East Sussex is a major destination for horse lovers, with several stables and riding schools amidst miles of bridleway. Clark-Drain supplied drainage solutions to one of the forest's prestigious equestrian centres, which is undergoing development of its visitor amenities.The centre has installed 3,000 square metres of new paving and parking areas, along with other upgrades to its facilities. Contractor Codrin Iordache of Cody Building took the opportunity to use Clark-Drain’s new HD-PE Technodrain solutions for the first time. Codrin says: “I was interested when I heard about Technodrain as an alternative to the polymer concrete drainage channels we generally use. Technodrain seemed to combine value with meeting all our technical specifications.“We found that the lightweight system is easy to handle. It’s also clear that, despite being light, the drainage channels have all the strength required.”All the Technodrain channel installed at the centre is in fact load rated to D400 and able to accommodate vehicles up to 40 tons. This means the area is equipped to handle even the biggest horseboxes, including HGVs carrying up to nine horses.Channels of two sizes were sourced from the range for this project:1. An external depth of 210mm, internal width of 100mm and max through-flow of 8.25 litres per second. 2. An external depth of 310mm, internal width of 200mm and max through-flow of 42.6 litres per second.Integrating sump units with channel drainageAlso supplied were several Technodrain sump units. These remove silt from the surface water, preventing dirt and debris from entering the drainage system and causing blockages. Codrin says: “I was impressed by the sump units. As with the channels, the galvanised steel edging made it simple for us to integrate them with the 80mm paving. They also feature grating that bolts in place, which is really easy to remove for maintenance inspection and cleaning of the unit and the channels.“The design of the Technodrain system also means that it’s easy to connect units together. Simple tongue and groove joints allow for the installation of channels with a ready-mounted grating, saving time on site and providing accurate connections. We will definitely be using Technodrain again on future projects.”Cody Building sourced the Technodrain products through the Tunbridge Wells branch of Professional Building Supplies, who specialise in drainage products as part of their wider range. Terry Hallett says: “We have been talking to customers since Clark-Drain introduced the Technodrain range and have had a really positive response. People like the value the range offers, and the fact that the light weight makes the units easy to handle.“The light weight is also good for us as a merchant. It makes this product sustainable to transport, and the HD-PE construction means there’s less likelihood of channels cracking in transit. It will also make storage at our central warehouse and branches simpler, with fewer issues around safe handling to deal with.”WHY THESE PRODUCTS WERE CHOSEN:Value - Technodrain consistently adds great value to excellent specifications.Load ratings - units chosen for this project were rated at Group 4 (D400), suitable for HGV parking. Robust - the HD-PE (high density polyethylene) channels and sump units are resistant to a wide range of acids, salts and hydrocarbons.Ease of installation - the 210mm deep channels used in this project weigh just 15kg each, including the ductile iron grating and galvanised steel edge.System integration - products in the Technodrain range connect easily together using simple tongue and groove joints.

At a Glance:New £253m resettlement prison required complete and secure cabling infrastructureManufacture and off site build of completed chambers reduced onsite labour by one third minimising COVID / H&S risksLighter, recyclable materials cut fuel use, accelerated installation and reduced environmental impactHMP Five Wells has won 15 major industry awardsThe ClientKier (www.kier.co.uk) is a leading UK construction and infrastructure services company, providing specialist design and build capabilities for vital economic and social building projects across the UK. Kier was awarded the contract by the Ministry of Justice (MoJ) for a new build resettlement prison in Wellingborough, Northamptonshire – as part of their New Prisons Programme. The aim of the programme is to reform and modernise the prison estate to provide more safe, secure and functional prison places focused on supporting rehabilitation.The ChallengeKier needed a cable access infrastructure that could satisfy the extremely secure access requirements of a prison environment spanning a 36-acre site.Over 1100 components were supplied to ensure a fully secure cable access system with features such as custom cabling.Kier’s goals for efficiency and cost-effectiveness, as well as for environmental sustainability and social responsibility, is in line with their brand values.The site required a simplified installation, reduced fuel consumption and lower emissions solution that would both endure and be recyclable at the end of their life. The benefits of Kier’s approach came to the fore during the COVID-19 pandemic.As Kier’s project director Rob Stanton explains, ‘new ways of working and offsite manufacture were embraced to mitigate the impact of COVID-19 on project delivery’.The SolutionUsing polypropylene products from Clark-Drain, via subcontractor Mitchellson, significantly reduced the weight of the components as compared to traditional concrete. This removed the need for lifting equipment, reduced the on-site labour required (and the attendant health and safety risks), and dramatically shortened the installation time on this £253 million project.From a sustainability point of view, too, these lighter components scored highly, not only in respect of reduced fuel consumption and end-of-life recyclability, but also in terms of provenance, robustness, and therefore long-life durability.Clark-Drain also made several prior visits to site to assess the project requirements, and, based on these early engagements, added further value by designing, building and deploying, in relatively short timeframes, two new chamber bellmouths, to protect below-ground cabling. The bellmouths enable cables to be easily routed within the inner chamber walls during installation by site operatives, but also enable ducts to be securely housed and connected, inside the chamber walls, prior to concrete backfill being applied during installation. Clark-Drain manufactures over 70% of its products inhouse, including the completed chambers, which were manufactured and built offsite at its yard in Yaxley, Peterborough.Demonstrating its commitment to social value and equitability throughout, Kier also involved its Digital Apprentice trainees in the project, and created a project bank account to ensure easier and quicker supplier payment.Outcomes and ResultsThe figures speak for themselves:Cable access for the project is being assembled 22% faster than if traditional construction methods had been usedLighter materials meant that one third less labour was required on-site to install the chambersSurveys were carried out 70% faster using dronesMillions are being saved on post-project snagging using cloud-based review and QA technologiesThe project has won 15 major industry awardsAnd as for the environmental benefits, long life and recycling apart, the polypropylene chambers are only 38% of the density of concrete, greatly reducing the project’s fuel consumption and carbon emissions.Rebecca Wade, Bid Director at Kier, describes the project’s successes: ‘Thanks to the deployment of agile digital methods and next-generation suppliers, we are delivering efficiently and cost-effectively, whilst respecting our commitments to our society, our community, and our planet.’For more information on how Clark-Drain can help your business deliver robust, cost-effective, environmentally responsible cable access solutions, no matter how big or small your project, get in touch.

This large college needed to increase parking capacity for students and staff and commissioned a new 5,500m2 car park. Local planning guidelines encouraged a sustainable approach to drainage to avoid excessive run-off into the local catchment. It would be used throughout the year, so there was also a requirement to avoid standing water during heavy rain. As it would be in frequent use by large numbers of staff and students, the chosen surfacing needed to provide long term durability with minimal maintenance requirement.After discussions with the main contractor, Tarmac’s experienced team recommended ULTIPOROUS, their specialist porous asphalt car park surface. Using a modified binder and open aggregate structure, ULTIPOROUS combines excellent drainage characteristics with long term durability. It reduces direct surface water run-off to help meet planning requirements. It also eliminates the problem of both standing water after heavy rain and ice patches that can occur in cold weather conditions.

We have overcome the challenge of installing low channels in an existing reinforced slab at the southern entrance to the French station.We have supplied mini range polymer concrete shallow drainage channels. This range is specially designed for areas with height limitation and load classes up to C250. Since this specific case involved a pedestrian tunnel, channels with heel-proof grates that comply with PMR regulations for people with reduced mobility were installed.

The Leeds Arena, when completed, will be a 13,500 capacity entertainment focused arena. BLUCHER® have supplied over 70 drains from their adaptable range of floor drains for the concourse, plant room and kitchen areas. BLUCHER® also supplied BLUCHER® EuroPipe, their push fit stainless steel drainage pipework system which was installed in the kitchen and conference areas. BLUCHER® EuroPipe was specified over other metallic or plastic systems for two specific reasons, due to the potential heat of the waste to be drained through the pipework and A1 fire rating of the exposed pipework in general.

Located in the Royal Borough of Kensington and Chelsea; one of London’s most prestigious locations is now home to an exclusive collection of luxury apartments and penthouses. 375 Kensington High Street is now one of the most sought after addresses in London, setting itself above all others and serves as the epitome of London living. Wetroom Materials worked hand in hand with the architects and contractors to overcome the varying challenges the project presented. 300+ low profile wetroom solutions were able to be supplied to the development.The Unidrain linear drain system 1004 model finished with the highline custom tiled panel was the chosen drain. This was supplied as part of the Unislope 1K kit, which couples the drain up with a preformed slope and waterproofing solution.

The playground area of approximately 50m² stretched across some well-established tree roots, it was important that when resurfacing this area the roots were not damaged but also received sufficient water, SureSet resin bound gravel is a SuDs compliant paving material, that water drains through reducing puddling but would ensure water would drain down to the tree roots or any nearby runoff points.

Our customer required a solution where the floor drains and channels could withstand the variance of temperature in the spa, and support footfall from the public, whilst maintaining an luxurious appearance in line with the environment. Alongside the drains for the changing room showers, using a bespoke design, BLÜCHER created a circular channel to surround the ice fountain, and an arched channel in grade 304 stainless steel with an infill grating to accompany the experience showers. Our infill gratings were the perfect choice for this spa setting, allowing a flawless finish of the chosen floor type against the drainage, completing the aesthetic appeal of the room

A previous client of Renderseal Ltd – who had works undertaken on his home in Hampstead in 2013 – requested help recently with further works at the same property.Due to a defective external drain problem, water ingress had occurred in the client’s rear bedroom in addition to damp staining and paint blistering in the side entrance hall.Familiar with Renderseal Ltd’s expertise, the homeowner returned to the waterproofing specialist for help. Providing its services throughout London and the Home Counties, Renderseal Ltd’s plan was to install a Sika waterproofing system that would combat the issues created by the home’s defective drain.

Yorkshire Sculpture Park at Bretton Hall estate is the largest of its kind in Europe with growing visitor numbers year on year. As a result the site suffered from insufficient parking with the site’s overflow areas becoming unsuitable with uneven ground prone to rutting, localised flooding and loss of traction. To combat the sloping, poorly drained site ABG provided a highly efficient SuDS drainage system, employing a combination of their Geogrids, Geotextiles, and Deckdrain, all in conjunction with the free-draining surface of the Sudspave 40 permeable paving system to resolve the access and parking issues for the 150,000 vehicles that visit each year.

In the industrial area of Cambridgeshire, specifically in Alconbury, the toy company John Adams has a warehouse where, in the outside area and car park, they have installed 200 ML of Multi V+ channel with load class D400, which, as I mentioned at the beginning, drains rainwater more quickly.Why do they achieve this?Because its design has been optimized so that a smaller channel can be chosen, i.e. one that is cheaper, but drains the same amount of water as a larger channel. In this way, the cost of the work or project is optimized.But it doesn't end there. The V-shape of this model, by draining the water at a higher speed, has a greater capacity to drag the sediments that accumulate inside the channel. In this way, a self-cleaning effect is achieved. And how does this benefit the drainage system? Less maintenance and savings in cleaning costs. Because the V-shape provides:More velocity at low flow ratesMore capacity at extreme flow ratesThis is because ULMA has redesigned the V-section of the Multi V+, and it is larger than the traditional V-sections on the market. 

Architectural glazing systems by Kawneer were specifically selected for a £18.5 million extension to the UK’s oldest business school for their ability to meet the building’s design aesthetic and high-performance requirements. The new 3,000m2 extension features Kawneer’s AA®110 and AA®100 mullion-drained curtain wall systems with capped and capless mullions as well as AA®100 zone-drained fully-capped curtain wall. The AA®100 system, with 50mm sightlines, was used in all areas with the exception of two full-height curtain wall screens which featured on the building’s ‘social space’ characteristic that utilised the AA®110 system with 65mm sightlines.

WILDLIFE KERB SOLUTION FOR PERTH AND KINROSS COUNCILWhen local wildlife rangers reported significant numbers of amphibians trapped in roadside gullypots, Perth and Kinross Council were concerned that many of these animals would be unlikely to escape or survive. In order to provide a safe and sustainable solution to prevent this issue, the council turned to ACO’s Wildlife Kerb to eradicate the problem.  Following prior observations during routine drain maintenance, Perth and Kinross Council Countryside Ranger Service set out to conduct the Amphibians in Drains Project throughout the region. The surveys revealed that significant numbers of trapped amphibian wildlife – primarily frogs and toads – were being found, having fallen through the drain grid. In fact, nearly 70 percent of the gullypots surveyed contained amphibians and small animals. Crucially, once trapped, it is unlikely they are able to escape or survive. Furthermore, the majority of animals were found in August and September, and the road gullies they had fallen down were less than 500m from a breeding pond – which suggests they were dispersing to their hibernation sites. This gave rangers enough information to infer that roadside drains have a significant impact on their populations. Amphibians typically follow the side of the kerb along the road which directs them straight into a traditional gullypot. Following funding from the SITA Trust, the Ranger Service was able to obtain ACO Wildlife Kerbs, which provided the perfect resolution. As part of their eco-friendly design, ACO Wildlife Kerbs contain a recess which allows amphibians  to follow the lower edge of the kerb and bypass  the gullypot.  The council piloted the use of Wildlife Kerbs at a site on Elm Drive in Blairgowrie. Following the success of the trial, the products were subsequently rolled out throughout the area.To read the full case study visit www.aco.co.uk/casestudies

A popular brewery brand recently expanded its headquarters to support the increase in demand of its craft beer range. John Lord Flooring were approached to specify the resin flooring and Aspen Stainless steel products were utilised for the drainage system. The Uragard-HT62W antimicrobial resin flooring was an ideal solution for the project due to its durability, chemical resistance and anti-slip properties. The floors and drains worked hand in hand to distribute waste water into the central drainage channel within the processing area.Aspen Stainless Davos Plus drain channels were installed to cope with the high level of waste demand within the brewery. The channel profile was carefully designed to provide an easy to clean surface with a self-draining slope feature. The strictest level of hygiene standards are required within food and drink facilities due to the build-up of bacteria and possible cross contamination of liquids.   It's essential the drainage is perfectly compatible with the flooring to ensure a seamless connection and high performance. This partnership with John Lord supports optimum performance compatibility by preventing the elevation of floor plates that can compromise hygienic performance.The drain channels are designed in compliance with EHEDG (European Hygienic Engineering & Design Group) to support safe hygienic engineering in food manufacture. The EHEDG states ‘product contact surfaces must be easy to clean, non-absorbent and not present a toxicological hazard by leaching of substances and foodstuffs’ the cleanability of the drainage is also an important hygiene requirement as stated in the EHEDG ‘Improperly or insufficiently cleaned equipment cannot be effectively disinfected’ A perfectly fitted drainage system will have a positive impact on boosting the hygienic performance of the entire facility. This includes employee health & safety, operational costs as well as consumer safety. The dedicated project managers worked closely with the contractor during the installation process to ensure the highest standards for drainage and protection were achieved.

In addition to series 190 heavy-duty entrance doors, Kawneer AA®100 zone-drained curtain walling has been used within rainscreen cladding from the ground to second floors and at the upper floor levels of a courtyard at Tameside One, the second phase of VisionTameside, in Ashton-under-Lyne, Greater Manchester.

A small farm cottage in a Cornish Village has been transformed with a stunning large modern extension and balcony.The team of Camel Glass installers have been heavily involved in this home with the installation of windows, doors and the glass balustrade. This home is situated on the grounds of an old quarry, with views over the valley towards an engine house. The customers wanted to be able to enjoy their view to the maximum and using glass balustrade provides a safe and solid railing. This home is highlighted throughout with copper oxide furnishings, the front door and elements of the kitchen follow this theme while the sink splash back is made from glass petals in a beautiful glass meadow scene. The balcony glass was the last outside job to be done, having to wait for the kitchen counter to be installed through the French doors it was safer to install the glass after this had been carried over the balcony. Now that winter is coming the indoor jobs can be finished off and the home owners can enjoy their newly renovated home! This installer has used POSIglaze base-fix in black. Balcony Seal® has also been used to ensure water can run off the balcony under the channel without causing water ingress. Most balconies and flat roofs are built with a slight pitch to encourage rainwater to drain towards the edge of the roof. In these cases, the balustrade installer needs to allow for drainage points under the channel, to avoid water pooling around the edge of it. The Balcony Seal® system works by subtly raising the channel a few millimeters above the substrate on drain blocks. Notches on the top side of the drain blocks locate into the rebates of the POSIglaze channel, locking it into position before the system is bolt-fixed to the substrate through each block. 

This old Mill House in Cornwall has undergone a huge conversion and extension to become a luxurious five-bedroom home, protected by the failsafe Newton CDM System. Simon Williams purchased the 18th Century Water Mill in 2015 with a view to renovating, developing and extending the beautiful property, located in Blowinghouse just South of Perranporth, into his private residence.Once planning permission was gained for the required conversion and extension to transform the mill into a luxurious 5-bedroom family home, Simon liaised with CAD Architects on the design, which incorporated a waterproofing design specified by Newton.An additional large garage with charming two-bedroom ancillary accommodation was also added to the grounds of the property, which required specialist steel and concrete foundations, given the close proximity of the water.In order to restore the old mill and achieve a Grade 3 habitable environment, BS 8102:2009 recommends that a Type C internal cavity drain membrane system is one of the primary forms of waterproofing, as it is the most failsafe system that is least prone to defects and issues.The Newton CDM System is also completely maintainable, and was therefore ideal for the 18th Century structure, considering that Williams Creative Homes did not want to compromise the external appearance of the thick stone walls.The proximity of the river also meant that there was a high risk of water ingress, however, Newton's robust cavity drain waterproofing is designed to capture water using Newton 508 membrane on the walls, then drain it away via gravity using Newton Basedrain.Finished to an incredibly high standard by Williams Creative Homes, Simon has been living in the property ever since, whilst the Newton waterproofing system successfully ensures that his home is completely dry and protected.

The front garden consisted of the typical grass, a narrow footpath, and shrubs. It was prepared prior to arrival removing all elements including the soil which was made level and topped with a free-draining compacted stone, this is the required substrate for SureSell. Once the cellular structure is in place it's filled with loose stone and then suitable for a final layer of smooth yet permeable resin bound paving.

Heavy duty surfacing was required for new access roads and car parking areas as part of a project to extend this business park located close to the A1 near Biggleswade. Using HGV resisting Ultiphalt HD asphalt on access roads combined with ULTIPOROUS free draining asphalt on parking areas provided both sustainable drainage and long term durability.

This project had a wide ranging number of detailing factors to overcome with cladding abutment details and change in levels to be redesigned and encompassed into a system that also drained the roof areas of their historic high levels of standing water. Some of the existing construction build had not taken into account any suitable maintenance of the roof with sections being completely inaccessible and thus reducing the performance of the waterproofing.

Aluminium curtain walling by Kawneer has helped an award-winning and cutting-edge combination of industry and academia achieve a BREEAM “Excellent” rating. The National Automotive Innovation Centre (NAIC), at the University of Warwick, is one of the largest centres of its kind in Europe, and a partnership between WMG (University of Warwick), Jaguar Land Rover and Tata Motors UK and features Kawneer’s AA®110 mullion-drained curtain wall.

Multi V+ drainage channels have been installed in the outside area of the Jaguar car dealership.These channels with V-shape section, provide a higher speed with lower flows, and have been developed to drain water faster, improving the self-cleaning effect of the channel. Its optimized cross section, larger than the traditional V-sections currently available on the market, provides bigger hydraulic capacity for extreme flow situations. 

The White Collar Factory will be a mixed-use are of workspace, residential and retail, designed by architects, AHMM. The development, sited on London's City Road, comprises a new 16-storey office tower, a new public square and refurbished existing buildings to the rear. The new 2-storey basement has been waterproofed using a Type C system applied internally, to provide drained protection in accordance with BS 8102: 2009. The waterproofing was supplied by Triton Systems.

A range of specialist fittings were supplied by GEC Anderson, for use the police forensic laboratory.These included a large height adjustable examination table; cabinets shelving and work surfaces with integrated bowls, upstands and special drainers. Perforated, height adjustable stepless shelving (GEC Anderson V90 System) was also supplied.Single-piece L-shaped stainless steel worktop with integral bowls, integral upstands and perforated draining rack. Shelving and cabinets with 'D' handles.

The Lanesborough 5-star hotel on Hyde Park Corner, Knightsbridge in central London; is operated by the Oetker Collection, and is reputedly the most expensive hotel in the city.All the rainwater outlets on the roof were in need of replacement, and Holborn Asphalt needed a simple, effective solution that would be compatible with the waterproofing membrane that they were installing.An extensive number of our FarBo rainwater outlets were selected for this project - these outlets are perfect for this type of work as they fit neatly into any existing drains and downpipes.

Kawneer’s aluminium AA®100 zone-drained curtain wall and thermally superior AA®720 entrance doors feature on all elevations of Unit 216 at the UK’s leading science park, while AA®190 TB severe-duty doors have been used on the main entrance. The unit was taken back to a concrete shell and rebuilt with a brick and glazed façade by main contractor Hutton Construction and is now the new home for Amgen, one of the world’s largest independent biotechnology companies.

To maximise the value of the tree planting,the pits were used as storm water attenuation and treatment pits, taking water from the carriageway, passing it through a stone layer on the top of the tree pit and then filtering it down through the Arborsoil Hydro soil mix provided for the root growth. The water then transferred through a clean stone layer to an underdrain to a storm water drain. This method of conveyance gives an acceptable level of pollutant removal and slows the water down so that the existing drainage network can cope with the increasingly violent storm events.

Wetroom Materials were able to work closely with the architects and developers and propose a drainage solution that would create minimal issues during installation and provide a high-end finish that could be in keeping with the hotels’ prestigious status by using our wall mounted drain and our Highline Custom.

Helo was invited to design and build a bespoke steam room as part of a leisure complex redeveloped within a country estate. Using traditional Moroccan Tadelakt finish, an authentic hammam style steam bath was created. A challenge posed by this project was to achieve remote switching of the steam from the main residence over a distance of 350 metres, enabling the client to prepare the steam room in advance of use. Special design features were included. For example, an ornate pull handle and concealed linear drain at the room’s entrance.

Waterproofing design is a key and critical component for successful construction of below ground structures. Whether it’s a completely new build or making smaller changes to an existing property, waterproofing design should never be overlooked.Waterproofing might account for just a small fraction of a building’s total cost, but waterproofing defects can result in catastrophic consequences. When waterproofing fails, the implications are significant.Delta’s MD, Kevin Dodds was approached to offer advice and guidance on a failed waterproofing system.The existing structure had an impressive 5-level basement which houses: kitchens, food storage and food preparation areas, spa, plant rooms and accommodation. Near to a large river, the site sited well within the water table. The original waterproofing system was based on the secant piled walls and a block wall internally to provide a basic drained protection system with drainage holes at various points to drain to various levels.Over time, the third floor had become completely saturated with all levels of the basement experiencing water ingress in varying levels from damp patches to significant “jets” of water and flows of water through the secant piles.With remediation waterproofing design strategies, it may take some time to specify a suitable system. It is important that investigations are thoroughly carried out by individuals with the capability of diagnosing the defect, assessing the extent of that defect, and recommending a suitable corrective measure.
