A major United States oil refinery has chosen Hempel’s Hempaline solvent free epoxy lining as an interior tank lining for a 200 foot / 61 metre tank diameter sour cured oil storage tank.Hempaline epoxies are 100% solid materials that can often be applied in a single coat and have rapid curing properties. This saves our customers time and money in application costs and completion times. Faster project completion allows them to return a unit to service quickly producing revenue.Hempaline epoxy was chosen for this application because of its ability to resist acid conditions of the tank’s cargo, high sulphur crude oil. Hempaline will provide long lasting protection to the tank, minimising future maintenance and repainting costs.Our Hempaline Defend 630 is a fast cure, highly chemical-resistant internal coating designed specifically for severe service environments, such as those found in the oil and gas industry.

This South East Water contact tank has a constant output of 18.1 million litres per day, it contains water which is treated with Sodium Tripolyphosphate and sodium hypochlorite before entering the distribution network. The structure is of a ‘certain’ age and has a number of active leaks that have progressively worsened over time. As the tank is in constant use, it cannot be taken off-line and so a solution was required which could be undertaken against heavy flow of water with the tank still in use. 

A major US oil company was experiencing corrosion in its sour crude oil tanks. Chemicals and water in the oil were creating severe pitting and corrosion issues at the bottom of the storage tanks. They contacted Hempel looking for a long-term protective lining solution.A poor lining system can result in substantial losses. Tanks and vessels left out of service for repair, cost owners valuable time and lost revenues. Hempaline vinyl esters have been designed to resist against acids, caustics, strong solvents, oil and water, protecting assets and maintain the purity of the content of the tank.To combat corrosion in the customer’s sour crude oil tanks we recommended our Hempaline Defend 500 vinyl ester mat reinforced to line the tank bottom and also the bottom 4 feet of the wall surfaces.The high-performance scheme was applied following grit blasting and consisted of a single coat of Hempaline Prepare 120 primer. A first coat of Hempaline Defend 500 was then applied and whilst wet, a 450 gm/m2 (1.5 oz/ft2) chopped strand mat was incorporated into the coating. Following a light sanding to remove any upstanding fibres, a second coat of chemically resistant Hempaline Defend 500 was applied.

A Sealwall Tank manufactured by Whites Concrete has become part of Rampton Hospital’s new Energy Centre in Nottinghamshire, which is operated and maintained under a Carbon Energy Fund framework contract. Part of the new Energy Centre that provides heating, hot water and electricity to the Nottinghamshire Healthcare NHS Trust Hospital, Whites Concrete’s pre-cast concrete Sealwall Tank is a component of Rampton’s new effluent treatment plant—now a modern, automated system that meets both current environmental standards and future expansion of the site.

Shell Nederland operates a large fuel storage depot in Arnhem distributing fuel to gas stations throughout The Netherlands. With a number of storage tanks on site, regular maintenance to protect against corrosion is essential. In this instance, they required an internal lining for their Tank 214.Poor linings can result in substantial losses due to asset downtime as tanks and vessels are left out of action as a result of corrosion. It was essential that the tank was protected with a coating that would perform exceptionally with extremely corrosive contents, whilst maximising the assets lifetime and minimising downtime.Originally the project was set to be completed with another lining, but ultimately it was Hempaline Defend 630 Cure 72 Epoxy that was used.

2020 General Binding RulesFor decades, millions of septic tanks have been installed throughout the UK in rural and urban areas. Septic tanks are known to be ineffective at processing sewage to modern environmental standards, causing long-term damage to the country’s natural water infrastructure and wildlife.It was therefore inevitable that new rules and a code of conduct would be introduced to prevent the effects of wastewater pollution once and for all; The Environmental Permitting (England and Wales) (Amendment) (England) Regulations 2014 came into force on 1 January 2015 creating the General Binding Rules (GBRs) for septic tanks or small sewage treatment plants for domestic use. These rules are designed to reduce the level of pollution from sewage in the nation’s watercourses.The rules state that any existing septic tank discharging to surface water, ie, to a water ditch, stream or river, etc, must have been upgraded or replaced with a new package sewage treatment plant by 1st January 2020.  Failure to comply can incur significant fines from the Environment agency and delays in selling impacted properties.OptionsCurrent methods of discharging wastewater from septic tanksPrevious to the General Binding Rules, wastewater from septic tanks was typically discharged in the following two ways:Drainage fieldWastewater is released through a network of pipes in surrounding sub-soils, providing an additional form of treatment for the waste from the septic tank. This helps to ensure that the wastewater being dispersed does not cause pollution.Septic tanks discharging into a drainage field are not affected by the 2020 septic tank regulations.Directly to surface waterWastewater flows through a pipe directly into a stream, river or lake. Binding rules state that direct discharge from a septic tank into a watercourse is not permitted.So, what are your options?1. Connect to the main sewerThis may not be possible in remote locations, although pump chambers can be used to direct wastewater to the mains sewer.2. Install a drainage field(Designed in accordance with BS6297)This allows the septic tank to discharge wastewater into the ground instead of surface water. In many cases, the installation of a drainage field is not possible due to site constraints such as space and/or the soil not having sufficient drainage potential (ie, rock, clay, high water table).3. Install a Uni:Gem septic conversion unitA Marsh Uni:Gem can be installed and connected to a pre-existing septic tank. This treats the wastewater to a sufficient quality allowing it to be discharged to surface water. See below for further detail.4. Upgrade your septic tank to a Marsh sewage treatment plantThis eliminates the need for a drainage field and ensures that the wastewater is fully treated before being discharged. Options include the Ensign, Ensign Shallow and Ultra Poylok L.Uni:Gem★Marsh Industries, the leading UK manufacturer of package sewage treatment plants, produces over 3000 units per year. However the company’s range of Uni:Gem★ septic conversion units is the only product available on the market which can treat wastewater from an existing septic tank without the need for a complete replacement product or drainage field upgrade.To comply with the GBRs and current EN standards, the entire Uni:Gem range was redeveloped from the ground up and tested, not only to meet, but to exceed UK and International standards. The Uni:Gem★ was born – creating an ‘industry first’ 2020 compliant septic conversion unit with outstanding processing performance.The Uni:Gem★ range was tested in accordance with BSEN12566-3/A1:2009 and EN12566-6 standards at the PIA GmbH test facility in Aachen, Germany, over the course of 38 weeks with a daily loading of:Flow: 900 litres/day BOD: 360g NH4: 48gTesting occurred between November 2018 and August 2019 to ensure all seasons were covered whilst minimum/maximum temperatures were tested to assure Ammonia and BOD process reduction for the UK climate. Holiday periods were also simulated during the test procedure. Final test results yielded an output of 12.5:16:4mg/ltr (BOD:Suspended solids:Ammonia) that is well within national discharge consent requirements.The Uni:Gem★ is an extremely cost effective solution for converting any polluting septic tank into a fully compliant sewage treatment plant ensuring homeowners, estate managers, water companies/amenities have an effective way to keep the environment clean whilst providing a quick and efficient installation process.

The modernisation programme of the multimillion pound project involves significant remediation of previously abandoned land, followed by construction of six circular primary settlement tanks (PST) and a large activated sludge plant (ASP) with 10 circular final settlement tanks (FST). This work will lead to significant environmental benefits for the site, improving the outflow, and subsequently the quality, of water entering the Manchester Ship Canal.

The design in this project was to have a Green Roof and warm roof system The aim was to place standard green roofs which retains water but allows most of the rainfall to run into buried SuDS tanks. Following consultation with ABG the design was changed to the ABG Blueroof system. The primary advantage of the system is that utilising the roof construction for water storage reduced the need for underground attenuation tanks. The simplicity of the design allowed for attenuation capacity and green roof installation at the same time saving the client time and money.

A residential dwelling with a failing septic tank located very far from the property, no longer fit for use required a new sewage treatment plant.

Moreland Primary School is a purpose built school, nursery and Children's Centre requiring a multipurpose usable outdoor space. Due to lack of space, the ground attenuation tanks planned would reduce site storage and limit access to other trades, therefore delaying the project, The challenge was to develop a storage/discharge system which wouldn't impact the project and be sensitive to the local biodiversity action plan. ABG designed a versatile Blue Roof System removing the need for attenuation tanks and allowing the roof finishes required. ABG bio-diverse roof system helped maximise the BREEAM credits laid out in the action plan

JACKOBOARD® by BEWI offers many benefits for installers of wetrooms and bathrooms. JACKOBOARD® is a waterproof, weight-loading and thermally insulating construction board for use in all types of tiling jobs.Critically, because it is manufactured from 100% waterproof XPS, there is no need to tank wetrooms constructed using JACKOBOARD®, either with a waterproof membrane or a paint-on solution. This saves the installer both time and money, since a separate tanking system is not required and only the joints where the boards meet need to be taped.The NHBC Standard states that “backing surfaces may require protection from a suitable tanking system”.“This guidance is completely correct,” says Martin Harragan from JACKON by BEWI, “but it should not be interpreted to mean that if you are using an XPS backerboard, such as JACKOBOARD®, you have to tank the entire substrate of your wetroom. The closed structure of an XPS board means that it is totally impossible for water to pass through it, in the way that it would through a fibre cement board for instance.”JACKOBOARD® is keen to communicate this message to the many different trades who get involved in the installation of wetroom systems, from the shower tray upwards. Although there are wetroom specialists, this job is often down to plumbers, M&E contractors, tilers, dryliners and flooring contractors. So, as wetrooms continue to increase in popularity, there are different trades who need to be aware of the benefits of XPS backerboards.While offering the benefits of XPS, JACKOBOARD® can also offer a price advantage in the marketplace, due to the fact that the company manufactures its own foam, giving it complete control over cost, product quality and sustainability of manufacturing processes. These factors have enabled JACKOBOARD® to become the UK market leader in XPS construction boards.

In looking for a full tanking solution for the ensuite bathrooms of renowned chef Michael Caines’ dream project, stone specialists Devon Stone elected to use various forms of the multi-functional tile backerboard Schlüter®-KERDI-BOARD.

Gowriehill Distribution Service Reservoir is located in Dundee City and managed by Scottish Water. In late 2021, part of the reservoir tank construction was discovered to have a brittle asphalt waterproofing layer over the top of a beam and block roof. Fosroc proposed a solution that was easy to apply and provided a robust watertight finish and a 20 year warranty.

Eco conscious barn conversion Landscape Design company Gardens Sorted specialise in renovation and bespoke garden installations. This project is a former farmyard and threshing barn conversion, the brief was to follow sustainable principles, the artifacts used around the garden are largely reclaimed, reused or recycled agricultural items.The client gardens by organic principles therefore the need for non-PVC galvanised rainwater goods was paramount. Chris Bligh, designer and installer at Gardens Sorted describes the installation: ”The rainwater solution required the high roof gutters to be deep profile, maintenance free, non-blocking outlets, and a long elegant downpipe into the storn water drain accross the yard. The addition of a rainwater diverter at the lower section afforded connection to a pressure water hose under grounded to two bends emptying into a reclaimed galvanised water tank. The hose is always full of water to the height of the tank. The important value of this is that the client can then dunk a large watering can into the deep water at waist height.” Chris adds that Lindab’s Rainline products are very good and he was grateful for a high standard of customer service.

The Faculty of Humanities and Arts is the third largest faculty in the Macau University of Science and Technology, The construction of the Complex Academic Building of College of Humanities and Arts – Block “R” includes a 2-storey basement and 7-storey above the ground floor. The height of the building is 30.75m. Caltite System has been applied in the basement slab, (B1 to B2), basement wall and water tank for long-term reliable waterproofing.

On the outskirts of Bristol in a busy residential area Wessex Water were tasked with providing a solution to a historic surface water flooding problem which could provide storage during heavy storm conditions. Several options were considered during the design stage but with the restrictive location a solution had to be developed that could provide the necessary storage volume within the existing carriageway as there were no available plots of land to locate a large storage tank.

With LivePicture GO you can add a splash of vertical greenery in a playful way to your living, learning or working environment. You don’t even have to have “green fingers” for the care of the plants; the water detector indicates when the reservoir needs refilling. The water supply within the tank is sufficient to provide the plants with water for ± 4 weeks. The capillary action within the plant cassette provides the plants with just the right amount of water they need.

Mapei systems have been used in the construction of a swimming pool at the American School in London, St John’s Wood. Complete waterproofing and ceramic tiling solutions were installed over a nine month period to areas in the pool tank and changing room interiors and exteriors. The project was completed whilst the school remained open, which meant materials had to be installed quickly and with as little disruption as possible, without compromising on quality.

In 2017 permission was granted for the re-devlopment of an abandoned mill in Holmfirth into a cookery school and restaurant. The design required the car park to look as natural as possible but to withstand the manoeuvring of large delivery vehicles. ABG offered a re-engineered solution showing that a porous type 3 attenuation stone over the whole car park removed the need for expensive attenuation tanks. The main car park was covered in Sudspave interlocking pavers coloured to match the gravel. Truckcell was used for the turning area and filled with the same gravel for a natural finish.

The former Royal Mail owned building at 160 Old Street, London, utilises 'blue roof' SuDS attenuation and biodiverse roofs and/or composite decking, retrofitted on 16 out of 29 different roof zones across multiple levels.The ABG blueroof system was specified to slow surface water run-off during key extreme rainfall events, in line with planning consent requirements for the provision of SuDS. The roof level storm water attenuation system was deemed the most cost-effective solution for the restricted urban site and avoided the need for an expensive and carbon intensive basement attenuation tank. 

The challenge was to incorporate a green roof finish both flat and curved to the roof areas. The roof pitch being as steep as 45 degrees in places, a pitch not conducive with a green roof system. ABG used their expertise in green roof and slope stabilisation to make the curved green roof possible. The system incorporated a series of anchor points, reinforcement geogrid (Trigrid), and geocellular technology (Erosaweb) to retain growing medium on each roof. The Green Roof system incorporates a SMART rain sensor and automated irrigation pipe system with each finger haveving its own dedicated mains operated tank

Quarry Bank MIll is an old cotton mill. Now operated by the National Trust it attracts large numbers of visitors daily to its attrections. The overflow car park quickly turns to mud currently being fit for purpose fields. A permeable surface was required however to allow for a permeable surface large tanks would be needed to store rain water infiltration. ABG Sudspave was chosen to provide a permeable surface and allow water to infiltrate. Sudspave can be quickly and easily installed and cut to size on site. Sudspave can be finished with either gravel or grass for a natural finish.

As part of a major Heritage Lottery funded refurbishment project to transform Hull’s Grade II* listed Maritime Museum, Limelite Whitewall One Coat Plaster was chosen as part of a damp proofing system for the converted basement. The moisture resisting properties of the plaster makes it ideal for use with cavity drain membrane systems and tanking systems in underground and humid environments. By helping to control humidity it would protect museum artifacts while in storage . The tough, impact resistant finish would also help protect the walls from accidental damage when items were moved in and out of storage.

Ceramic tiling contractors P.Plunkett recommended Howe Green Medium Duty 7500 Series 316 Grade Stainless Steel Floor Access Covers as a reliable and safe solution for accessing the pool sumps and pool balance tanks located beneath the tiling in the pool areas at East Riding Leisure Centre. Nine 7500 Series access covers were fitted into the ceramic tiled floor around the pool surround and infilled with antislip porcelain floor tiles to provide a flush finish, that is functional and aesthetically pleasing. The 316 grade stainless steel cover is non-corrosive and will not rust, even in a swimming pool environment.

The Tate Modern’s Switch House is a new pyramid-shaped tower is built above the former power station’s subterranean oil tanks. The extension, which can be seen as you approach from the north, comprises ten floors that become incrementally smaller towards the top of the tower and culminates in a spectacular public roof terrace. Visitors to the roof are rewarded with 360-degree views of the river Thames, St Paul’s Cathedral and the London skyline, and you can see as far as Tower Bridge, the Old Bailey and Wembley Stadium.Radmat Building Products supplied a waterproofing solution to roof and viewing platform on the newly opened extension.

The 2014 Commonwealth Games’ swimming competition was played out at Tollcross International Swimming Centre. In anticipation of the games, the centre’s facilities underwent a complete refurbishment. Some of the screed below the tiles on the main competition pool floor had separated from the concrete pool tank. The entire floor needed to be re-laid. Glasgow City Council Scott hired, Tilecraft, a specialist tiling works company that delivers high quality tiles, to lay the tiles and specified products from ARDEX UK. A fast track solution which would produce high quality results was needed, and ARDEX UK seemed the logical choice.

The designer obtained consent under the latest SuDS regulations in the densely build area of London. Restriction on outflow rates to sewers demanded high attenuation. The original design for stormwater attenuation involved discharging tanks under the ground. This was expensive and took up valuable space, an alternative was required. ABG proposed their Blueroof system which could be installed directly on to the hot melt waterproofing system allowing various surface finishes. Due to height limitations a cascade system was used. Various roof finishes included paved access, landscaped areas and bio diverse to attract wildlife. This increased the potential for BREEAM points.

Kings Cross Package 4. The tanking material had to succeed where the specified competiton fell short : all weather installation; self-healing/sealing capabilities; one product application ; mechanical not chemical bond to concrete. It also had to meet the specified requirements of BS8102 1990 Grade 4. The solution was 8000m2 of Voltex, containing zero VOC, installed in almost any weather conditions to green concrete, and proven effective on both new and remedial waterproofing projects worldwide. Aided by CETCO holding both ISO 14001 & 9001, and the properties of Voltex, the project achieved its CEEQUAL award, scoring above 75%, and rating Excellent.

Providing a complete abP-approved, CE marked and BBA accredited waterproof system, removing the need for labour intensive tanking because no further sealing is required.

Abode was the tap designer of choice to inject eco-luxe convenience to a unique water tower restoration project in Castle Acre, Norfolk with Pronteau: a high-specification range of steaming hot water taps. Paul Illingworth, Design Manager at Abode says, “We were delighted to be a part of this project alongside property owner Dennis Pedersen and Tonkin Liu Architects, as they meticulously came together to reimagine a derelict industrial water tank into a contemporary, family home. Dennis purchased the water tower at auction for £20,000 in 2015, and then project-managed all the building work himself to save money and realize Tonkin Liu’s architectural vision with the help of a local builder. Following the addition of a new CLT timber tower and careful infilling, the original water tank is now an open-plan kitchen living space complete with Pronteau Propure 4 IN 1 steaming hot water tap in ultra-fashionable Urban Copper finish. As the property needs to cater to a family of four, the additional breakfast room on the second floor, is also designed with a Pronteau Propure 4 IN 1, to ensure the height of convenience, design continuity and eco luxury in the modern home and living space.”  The 160 sqm Water Tower project, is testament to the increasing demand and complexity in personalised building projects across the UK. As the trend for flexible kitchen living is a key focus for today’s multi-generational homes, homeowners want to make sustainable choices wherever possible. Pronteau by Abode is the ideal way to combine high function design with a superior style, heightened level of safety and sustainable consideration in reducing the consumption of plastic bottled mineral water.  “We believe that safety goes hand in hand in interior design and construction, which is why we continually invest in new product development to ensure our designs are fit for purpose. As a practical example, our exclusive Filter Recycle Scheme enables end users to return redundant filters directly to us for recycling.”

This project involves the partners Fremek AB, Totech AB and PCP A/S.Fremek is a workshop company in Dals-Långed that is certified according to EN-1090, EXC1, EXC2 and EXC3. Fremek specializes in welding, cutting, painting and assembly of large projects throughout Sweden.PcP’s solution includes CUBE® gratings and treads for a modern design and ladder systems for worker safety. Fremek and Totech chose PcP’s solution to install a new fuel station for Air BP, one of the world’s largest aviation suppliers.Project criteria - Slip-resistant steel platformFor this project, Air BP required an anti-slip platform due to the use of oil during maintenance.Although the platform is new construction, it was erected on an existing outdoor structure with nothing but a roof and fuel tanks. Thus, there were specific dimensions required.Therefore, PcP provided a more efficient fuel station platform and a safe working environment for personnel carrying out aircraft maintenance.The project had a strict timeline of 10 weeks as the construction had to be finalised before winter.Fremek was responsible for designing the air-plane fuel station and for sourcing the correct materials. Fremek contracted Totech for the works. Totech has more than 25 years of experience managing complex projects for a range of industries and, therefore, extensive knowledge of industrial construction and of which materials to use.PcP has delivered gratings to Fremek in several previous projects. Totech, therefore, approached PcP to showcase gratings with high slip-resistance for the platform. Totech seeked to use standard sizes to meet customer requirements of lead time and budget. At this point, Totech discovered that PCP also could provide handrail and ladder systems.Project solution - CUBE gratingsThe PcP CUBE® gratings, treads and toe-plate were provided for the platform in standard sizes. For easy access to the platform, PcP provided fire escape ladders and safety handrails. PcP CUBE® gratings and treads benefit from outstanding high PTV slip-resistance reducing trip and fall risk, lightweight but strong and fitted perfectly into the existing construction from the ground to roof.Fremek installed the platform, and the workers on-site made cut-outs to suit various plant equipment. Additionally, PcP provided escape ladders to mount on fuel tanks. In case of fire incidents/emergencies, enabling workers to escape rapidly.

St James Quarter is an impressive new galleria retail shopping centre and residential development that rejuvenates a large area of the New Town in Edinburgh city centre. The site was formerly occupied by a dated 1960s era shopping precinct, and with the exception of the John Lewis store, all of these old buildings have now been demolished to make way for the new development. The £1 bn project creates 850,000 sq. feet of new retail space, with a capacity for 80 units focussed on high-end retail alongside the Bonnie & Wild’s Scottish Marketplace and Food Hall.Such a large city centre development is subject to strict planning conditions for the management of surface water. The Water Environment Regulations3 (CAR regulations, Scotland) require all surface water from new developments to be attenuated and treated by a Sustainable Drainage System (SuDS) before it is discharged into the water network. The aim of SuDS is to mimic natural drainage, encourage infiltration and attenuate hydraulic impacts to minimise downstream flood risk. Excavating underground storm water storage tanks to control surface water run-off was not possible since three levels of basement parking are incorporated beneath the retail centre. Even where possible, basement tanks are comparatively expensive compared to roof level attenuation systems, with high spoil disposal costs, increased safety risks arising from the excavation activities and a large carbon footprint incurred as a result of the number of additional site vehicle movements.The proposals for drainage and SuDS at the St James Quarter development were mainly focussed on the large 15,000m2 catchment area on roof level 5, with 4,734m2 of 80mm deep attenuation void capacity installed by ABG’s installation division ABG Installs. The blueroof system treats and restricts storm water that deluges onto the roof before it is gradually released over a number of hours via outlet control and filtration chambers to the underground drainage system.The attenuation and restrictor chambers on level 5 (east and west of the soon to open central circular W hotel building) and onto balcony areas 1 and 2 at the front and back of the upper apartment buildings, are supplemented with an additional of 2,280m2 of ABG Roofdrain geocomposite, installed at the base of rooftop planters to provide a connected drainage and irrigation / reservoir layer as part of the landscaping design.ABG calculated and designed the required attenuation capacity, including a new diffuser chamber solution to control water outflow at downpipes.
