"separating membranes geotextiles"

Koster Aquatecnic were approached by the project architect to assist in a specification to renew the waterproofing to the roof of the large visitor cottages at the base of Ardnamurchan Lighthouse.This lighthouse is situated at the most westerly point in the British Isles and as such is extremely exposed to the elements. A robust material and system had to be produced. This was a very challenging project and a great deal of assistance was provided including bespoke drawings, office and site meetings followed by leak testing services to ensure fully watertight.Please read through the case study and if you have any questions or would like advice on a similar project, please contact technical@kosteruk.com.

A new terminal at the Port of Cork will provide a 360m quay enabling larger ships to berth in Ringaskiddy, accommodating current and future container shipping. Geofabrics HPS6, a needle punched nonwoven geotextile was installed by BAM as a filter preventing displacement and erosion of submarine soils.

The £14m Arnold Hill Academy is part of the Priority School Building Programme (PSBP) and is being constructed adjacent to the existing school in Nottingham. The new Academy’s 3,570m2 flat roof covers 8,200m2 of replacement teaching space, science labs, an indoor sports hall and a drama studio. The project team at Wates Group had already identified potential roofing products. Due to the unconventional roof specification they asked SIG Design & Technology to recommend a product that would work in tandem to deliver the required performances.

When specifying the most appropriate method of waterproofing for a new-build basement it is advisable to follow the recommendations within BS 8102:2009 ‘Code of Practice for Protection of Below Ground Structures Against Water from the Ground’. The standard advises on the types of waterproofing available and confirms the performance grade to be achieved. This project required Grade 3 protection – no dampness or water penetration acceptable.

An innovative and comprehensive waterproofing solution was required to facilitate a £18m state of the art hotel and with a double story basement in Englefield Green, near Windsor. The hotel will offer exceptional overnight breaks, award-winning dining & an exclusive spa facility once completed.

Delta’s Structural Waterproofing Consultant, Paul Green, CSSW alongside Delta’s MD, Kevin Dodds, were appointed to the design team to collaborate with the Architects, Engineers, Main and Sub-Contractors to fulfil the role of Waterproofing Design Specialists in providing a reliable, watertight solution for this substantial project.The large-scale basement project consists of a 4-storey deepbasement located close to the River Thames in Central London.The proposed subterranean space would offer multiple usage. This complex project required a waterproofing design which is, able to cope with intermittent/regular hydrostatic pressures created not just by groundwater, but also geographical tidal impacts from the river Thames and potential stress challenges caused by the surrounding infrastructure such as heavily trafficked railway lines in the development’s vicinity.Structures that experience a high level of vibration fromsurrounding infrastructure can, over time, have a high propensity to suffer cracks, which could lead to failure of some waterproofing solutions, so therefore careful considerations should be incorporated into the overall waterproofing design from those aspects and, the impacts these factors can have on an elected waterproofing system.Delta’s design philosophy rotated around creating a robust and suitable waterproofing design, the structure design, a continuous system, sequencing and installation, future maintenance, and serviceability, whilst able to fulfil requirements set out in BS 8102:2022 Protection of below ground structures against water ingress. Code of practice. The British Standard which governs waterproofing of substructures.

RENOLIT ALKORPLAN scores high on Deltion College! CHALLENGE A sports field on top of the roof. A surprising and exceptional RENOLIT achievement that absolutely draws the attention… Deltion College in Zwolle (NL) really is an exceptional case. This college offers amongst others education courses to prepare for service in the Armed Forces - Navy, Army as well as the Air Forces. No doubt sports are an important part of life on the campus. Then came the inspiration to install an artificial grass sports field on top of the roof of the newly constructed multifunctional building. Space-saving and functional! The choice to specify RENOLIT ALKORPLAN as roofing material was a shrewd decision, as RENOLIT ALKORPLAN offers a solution not only for mechanically fixed roofs but also for ballasted roof systems… SOLUTION The highest rooftop, a steel frame construction, has been installed with a PES-reinforced mechanically fixed RENOLIT ALKORPLAN F roofing membrane. For the lower concrete roof – the sports field to be – a different product was required: RENOLIT ALKORPLAN L! A glass fleece reinforced membrane with an excellent resistance to microorganisms, specifically conceived for ballasted roofs. Before installing the insulation, a bituminous vapour barrier was placed on top of the concrete. Next came a first layer of 70 mm thick aluminium-faced PIR insulation, followed by a second layer of 100 mm thick unfaced polystyrene insulation. To avoid direct contact between the roofing membrane and the PS insulation a glass fleece separation layer was added. Afterwards the RENOLIT ALKORPLAN membrane was loose laid and hot air welded. In accordance with the RENOLIT installation instructions the seams were sealed with RENOLIT ALKORPLAN seam sealer. A little bit of effort for extra security! 

The Wickes Farnbrough DIY store is one in the latest Wickes stores to have been developed by Travis Perkins as part of its ongoing plan to double its UK store network to 400 by 2020.The project used Trimapanel® micro-rib 90mm on the front elevations and Trisomet® 80mm for the rear wall elevations; Trisomet® 120mm was used for the roof; and parapet gutters lined with a Colorcoat Aquatite® PVC membrane. (HR50) site assembled built-up system, which is being used as a feature on a number of the Wickes Stores, ran across the top of the Trimapanel® on the front elevation acting as a separator between the two units. LP1000 liner panels were also used internally.

Geofabrics HPS5 was successfully installed below the rock armour on the River Aire’s flood plain. Geofabrics HPS5 is a thick needle punched nonwoven geotextile manufactured from 100% virgin polypropylene high tenacity fibres containing 1% active carbon black. The main function of HPS5 is to prevent loss of the subsoil from below the rock armour. HPS5 was ideal with its combined filtration and permeability characteristics whilst its high tensile elongation and CBR provided a robust solution capable of withstanding the rock impact during installation.

The client desired a green roof at the back of this beautiful family home. Access was very restricted. The speed and ease of transporting and installing our modular trays meant minimum disruption for the homeowner. Trays were delivered to site on pallets and handballed to the roof. The modules were laid down onto a geotextile fabric. Pebbles were then laid around the perimeter between the trays and any outlets to provide the required firebreak. Vegetation blended quickly creating a seamless green roof and, looking out from the upper floors, a sense of continuity from the house across the garden.

This project involved a brand new Starbucks drive-thru being built in West London where the customer wanted the overlooked rooftop to be green. The customer was able to give the basic dimensions to our team and describe how they wanted the roof laid out. We then calculated the exact quantity of units needed with our inhouse software and gave delivery and installation guidance to the contractor and end client. Wallbarn also supplied the materials for the semi-extensive border including geotextile fleece, drainage board and our specially-developed substrate for a comprehensive green roof solution,

In 2017 permission was granted for the redevelopment of an historic abandoned mill in Holmfirth into a restaurant and cookery school. It was soon clear the ground to be used for parking needed stabilisation. To completely dig out the area would have been costly and there was little time for unplanned work. ABG offered a stabilisation combination. Terrex SNW geotextile layer replaced the 50mm sand binding. Abgrid was used as a basel stiffening layer and Sudsweb tied to the grid with Abfix ties. Stone was then compacted ready for ABG permeable paving (see SuDS permeable paving Sudspave, Devour, Holmfirth)

In 2019/20 works were undertaken to prolong the life of the promenade structure and adjacent shoreline at Aberavon. The implementation of the Shoreline Management Plan has served to protect residential and commercial properties from coastal erosion. Geofabrics HPS11C is a thick needlepunched non-woven geotextile manufactured from 100% virgin polypropylene high tenacity fibres containing 1% active carbon black. The main function of HPS11C is to prevent loss of the sub-soil from below the rock armour. With challenging low particle size subsoils, the HPS11C was ideal with its combined filtration and permeability characteristics.

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.

Another housing refurbishment is set to benefit from the high-performance Roofshield breather membrane. The world-renowned Roofshield membrane from the A. Proctor Group has long been recognised as a first-class roofing membrane solution, providing a pitched roof underlay that is air and vapour permeable.Specialist roofing company S & J Roofing in Bath has been providing roofing services since 1981 and has established a reputation for high-quality roofing work for all kinds of domestic and commercial works, from restoration to complete new re-roofs down to minor repairs.Naomi Richards of S & J Roofing commented, “we have used Roofshield on many of our projects, Roofshield will always be our number one go-to product. Using Roofshield leads to savings in both labour and material costs, keeping the installation team and customers happy. Roofshield was the most cost-effective solution to control the interstitial condensation in a pitched roof. Roofshield is the most reliable product on the market, so it is used on every one of our projects.”Roofshield is a unique, three-layer, nonwoven, spunbonded, polypropylene breather membrane with a patented melt-blown core, and it provides a secondary barrier to the ingress of rain, wind, and snow. Designed with a low vapour resistance, it is air-permeable, with the additional benefit that it eliminates the incidence of interstitial condensation in pitched roofs.The exceptional performance of Roofshield has been successfully incorporated in many of the most demanding locations worldwide. Its characteristics allow pitched roofs to breathe without needing air gaps or secondary venting. Its patented SMS (Spunbond Meltblown Spunbond) structure allows high levels of airflow and the transport of moisture vapour, making the formation of condensation in the roof space virtually impossible. Numerous vapour underlays use an airtight VP film layer to achieve their performance. However, the exceptionally high vapour permeability and air permeability of Roofshield means that it can perform in conditions in which air-tight alternatives will not.The exceptional air permeability performance of Roofshield means that the roof space will result in similar air changes to that of a roof using traditional eaves/ ridge ventilation. Therefore, another advantage of incorporating Roofshield into the roofing design is that it can lead to savings in labour and material costs due to removing the need for these vents as well as a separate VCL at ceiling level.

As a company passionate about UK manufacturing, Aston Martin’s choice to work with Polyroof - the only independent UK manufacturer of cold-applied liquid systems - was a natural one.The new roofing system had to be cold-applied to eliminate the risk of accidental fire during installation. New insulation was also desirable to further improve the thermal performance of the roof. It was essential to reduce disruption to the operations of the facility, meaning any new system must be rapid to install with the existing roof predominantly being kept in place.After leaks were reported, The findings of Polyroof’s survey were presented to Aston Martin in the form of a bespoke specification, where the Protec Warm Roof System was the recommended solution. Core tests taken during the inspection had revealed that despite the leaking through the existing PVC single-ply membrane, the existing build-up of 60mm PIR insulation was found to be dry and in sound enough condition to be retained as the base for the new roofing system, saving the client time on the project.It was also identified that the current insulated roof configuration was missing a Vapour Control Layer, meaning the roof was at risk of condensation issues. This problem was designed out by the installation of 120mm Polyroof RES Insulation above the existing single-ply membrane, which was made good to form an effective vapour control layer.By creating a “hybrid” roof with double the insulation above the vapour barrier than below, the risk of condensation was eliminated and this was demonstrated by analysis conducted on the proposed build-up.To eliminate the standing water issues, sumps were placed around the existing outlets, greatly improving their drainage capacity, and offering a highly cost-effective solution when compared to the need to alter the falls of the roof.Polyroof Technical Services visited site regularly to advise and assist architects, specifiers and contractors in all aspects of the project.The finished roof provided a seamless and extra-tough waterproof membrane that was supported by the trusted Polyroof Accredited System Guarantee, with a separate insurance-backing scheme provided at no cost to the client. Aston Martin Lagonda now have the peace of mind that the roof above this landmark facility will be leak-free for decades to come. 

A £1bn investment will re-instate the Royal Docks as a commercial and trading centre for the 21st century. The Effisus Ecofacade Envelope System and its Effisus Ecofacade Membranes, Effisus Breather+ Membranes, Effisus Vap Membranes and accessories, was chosen to address weatherproofing and air sealing requirements on facade cladding systems.

The newly redeveloped Heatherwood Hospital employs a total of 4,200m² of Sudsgrid 40 cellular pavers, filled with free-draining angular aggregate to provide 450 new parking spaces, delineated by yellow markers. ABG’s sub-base design utilises the unique Abgrid geogrid to reduce the thickness of DoT Type 3 stone required for structural stability, and through the use of the ABG Terrex NW non-woven geotextile layer, an additional stage of treatment was provided for the infiltrating water.ABG’s permeable paving limits surface water run-off and minimises the risk of localised flooding, alongside, providing a shallower construction profile. Resulting in reductions in site excavation, off-site tipping, DoT Type 3 stone deliveries and the associated costs.

To create a Blob... CHALLENGE For the design of a Texaco service station on the highway near Antwerp the architect decided he wanted to create a Blob (Binary large objects) architectural design. The service station consists of three functional lobes that together look like an oil stain. The actual gas stations are covered with 4 lobe-shaped canopies. To accentuate this futuristic design the architect wanted to create liquid formed shapes in a metallic look. As the walls of the main building were planned using a polurea metallic finishing coating the architect sought a suitable compatible material to finish the rest of his Blob roof surfaces. SOLUTION Synthetic roofing membranes are the most flexible materials on the market and are suited to waterproof almost all possible roof shapes. For this particular project the silver coloured RENOLIT ALKORPLAN membrane was the best solution. This silver membrane is produced with a protective coating creating a roofing membrane that is easy to clean. The RENOLIT ALKORPLAN Metallic membranes combine excellent durability with added aesthetical appearance.

Five domed design... CHALLENGE The idea of the architect was to design a building with 5 parabolic roof surfaces or domes. The unique five domed design comprises of pods finished in a range of different materials, each contributing to the development’s remit to blend into the park landscape. The biggest issue for the architect was how to connect these different materials to become a complete watertight building. SOLUTION Each dome is waterproofed using a RENOLIT ALKORPLAN system and whilst the complex is thought to be the UK’s largest timber-built geodesic project, it also demonstrates possibly the most innovative use of single ply membrane ever seen in the UK. By using the RENOLIT ALKORPLAN membrane as the main layer to waterproof the five domes an easy joint could be made by means of hot air. On one dome our RENOLIT ALKORPLAN A membrane was used in combination with PVC profiles providing geometric aesthetic detailing. On another dome a RENOLIT ALKORPLAN L membrane was used under a green roof system. On the other domes the RENOLIT ALKORPLAN F membrane was used in combination with our RENOLIT ALKORSOLAR fixing system supporting respectively glazed aluminium sheeting and cedar shingle tiles.

Fireshield® vapour permeable membrane, which is designed specifically to improve the fire protection behind cladding has been chosen for a new Science Centre at Bevington Primary school in the Royal Borough of Kensington and Chelsea, London.The project includes a brand new Science Studio, plus before and after school club buildings.SIP Build UK was appointed as frame subcontractor for the project and chose the Fireshield membrane as part of the SIPS panelling system. Chris Duckworth from SIP Build UK explains: “We chose Fireshield as it provided the project with a number of really important benefits. Fireshield is a high-performance breather membrane which enables us to achieve the requirements in terms of fire protection without compromising on vapour control.Fireshield was also ideal because it is easy to use and allowed us to achieve the requirements in one process, using just the membrane, rather than the typical approach of two, cement board and a membrane.”Fireshield is the culmination of leading research to produce a vapour permeable membrane with a intumescent coated surface, which has a unique composition that actively reacts to help protect the materials underneath. The intumescent coating helps protect the substrate by reducing the risk of fire taking hold and significantly reduces the formation of droplets and smoke.The BBA Certificate awarded to Fireshield confirms that it has enhanced performance in relation to reaction to fire classification, will reduce the risk of interstitial condensation, and will have a life equal to that of the building in which it is installed.Fireshield complies with BS5250, BS4016 and NHBC requirements for vapour permeable walling underlays. It is installed and fixed to the substrate in the same manner as standard breather membranes using mechanical fixings. Applications include both commercial and residential buildings including apartments and student accommodation, as well as Rainscreen cladding and applications over 18m high (11m in Scotland).

Friesland Campina CHALLENGE An absolute must for refrigerated warehouses or dairy processing facilities is to try to keep the building as cool as possible and to avoid all causes of heat, in order to keep the cooling costs as low as possible. Some decisions can have detrimental effects though. Mechanical fixing of the roofing membrane for example, in case the wrong fastenings are used. Thermal bridging may cause cold – or in this case heat - penetrating through the flat roof fasteners resulting in higher energy bills. And, quite important as well, mechanical fixing will perforate the vapour control layer, which in the case of cool buildings sits uppermost on the insulation. The result being moisture-related damage to the insulation! Furthermore, it has also been proved that the darker the roofing membrane, the less the sunlight will be reflected, the more heat will be absorbed. Again resulting in escalating energy costs. Waterproofing a cool storage warehouse is definitely not easy! In this regard Friesland Campina were looking for a durable and ecological roof solution for their brand new refrigerated distribution centre in Maasdam. SOLUTION RENOLIT came up with the perfect answer: the RENOLIT ALKORBRIGHT cool roof membrane. Here’s why! RENOLIT ALKORBRIGHT is a completely white PVC membrane reflecting the sunlight up to 90%. Absolutely the highest solar reflectance rate ever. Thanks to this membrane, which prevents the interior from warming up, there will be no extra air conditioning expenses. In addition, an extra protective coating makes sure less dirt sticks to the roofing membrane. This layer will in turn help to maintain a durable reflection. 

The Royal Russell School in Croydon demonstrates the vast variety of waterproofing applications with which DANOPOL membranes can be specified. From standard flat roof areas to pitched standing seam roofs, vertical applications and accessible terraces, the flexibility of specification is really showcased on this project. The most noticeable feature is the stunning standing seam roofs, which are also DANOPOL HSF+ membrane, completed with ALPHA PROFILES. These ALPHA PROFILES are raised PVC profiles made from DANOPOL materials which can be retrospectively heat welded to the surface of the completed waterproofing system. The use of Alpha Profiles is rapidly increasing as the design may be highly customised and the installed centres can be changed to suit a clients particular aesthetic preferences and are often installed to obscure any standard membrane overlaps. An advantage of selecting DANOPOL membranes over a traditional metal standing seam roof option is that at less than 3.00kg per m2 for the waterproofing membrane, the system is incredibly lightweight and may be installed onto many lightweight structural substrates. The reduced load, when compared to traditional standing seam roof options, can also translate into savings on the underlying supporting structure. Our DANOPOL+ HSF membrane was also utilised on the terrace areas, which included vertical detailing to clad the internal faces of the parapet walls, providing a fully-encompassing watertight finish to the roof areas. Waterproofing System: DANOPOL+ HSF 1.5mm - Dark GreyConstruction Type: New Build Warm Roof Sector: EducationApprox.

Roof with a message... CHALLENGEFor the renovation of the arena Antwerp Sports Palace the architect wanted to design a roof that gave a message. From the air people should see an “A” appearing. This A would be the A of the county Antwerp and not the A from the city Antwerp. Also with the possibility to have (solar) energy production installed on the roof. SOLUTION Six new colours within the RENOLIT ALKORPLAN roofing range were developed specially for this prestigious project. The existing green coloured synthetic roof was used as substructure. The whole roof received extra insulation (thermal and acoustic) and the new RENOLIT ALKORPLAN roofing membranes were mechanically fastened following an installation plan. All the membranes for the Antwerp Sports Palace not only had a special colour but also a special finish with an invisible protective coating. All membranes have excellent fire resistance for roofs with a higher slope. On the south side of the roof amorphous solar panels were installed upon the RENOLIT ALKORPLAN roofing membranes. 

This 115m² project was a large luxury new-build. The decking required two distinct build-up methods around the house. One section was on a waterproofing membrane, the other on a steel framed walkway. Adjustable support pedestals were loose-laid onto the membrane. iDecking aluminium rail system was set onto the pedestals and EasyClick boards were clicked into place. Pedestals lifted the decking structure off the membrane allowing free drainage and creating a level surface on the falling roof. Aluminium rails were mechanically fixed to the steel structure and the whole terrace was set to one, seamless level wrapping around the house.

A lightweight solution... CHALLENGE A lightweight solution was required for the mounting of the PV installation on a production hall from Opel in Rüsselheim. For some years there existed no smart solutions for PV installations on roofs. Today we start to see the downside of PV roof installations that are not coping well with the weather conditions on top of roof constructions. Common mistakes made on PV roofs: • PV panels flying off the roof due to high winds where the attachments have not been strong enough and not fully tested. • Water leaks due to structural damage from the PV installation itself. Mainly due to the minute movement of the metallic/ aluminium PV-mounting on the roofing membrane. • Water leaks due to perforations through the roofing membrane when fixing the PV installation to the roof. • Roofs collapsing due to an excess of ballast of the ballasted PV installations. • Accelerated ageing of roofing membranes due to the use of incompatible materials on the roofing surface. SOLUTION RENOLIT ALKORSOLAR PV fixing system. This lightweight PV fixing system does not require extra ballast nor perforates the roofing membrane. The main parts of the system are PVC or EVA profiles that are heat welded onto the synthetic roofing membranes. This system is the only system that is fully tested for wind loads up to 200 km/h, has an Avis technique (France) and a DIBT approval (Germany).

Slip-resistant steps for Villa ParkDegafloor were thrilled to be involved in the redevelopment of Aston Villa’s famous Villa Park football stadium. Slip-resistant steps were required for the Holte End of the stadium in addition to new facilities, including a new bar and suite complex.As part of the project, slip-resistant steps were required. The entire 600m² staircases were treated with Degafloor concrete crack seal, followed by a flexible waterproof membrane to deliver a impervious solution to protect the new bar and suite complex. The staircases were then finished with a bespoke Degafloor Quartz Trowelled with Aggregate System, finished in a unique Terracotta Quartz.To comply with current DDA legislation (Disability Discrimination Act) the stairs were finished with a separately formed nosing in White.Due to the tight project timescale and to overcome traditional British weather constraints, Flo-Dek (UK) Ltd recommended a range of fast curing Degafloor resin systems. As well as being fast curing, all Degafloor systems exhibit excellent UV resistance – essential for external environments – whilst the QTA system applied to the treads offers unrivalled slip resistance to ensure spectator safety, whatever the weather conditions.Speaking on behalf of Flo-Dek (UK) Ltd, Sales Director Dave Cope said, “This was a very complex and demanding project. The colours had to match perfectly and the hand formed nosings required a high level of skill and attention to detail”.

Raithwaite Hall is a 5 star, 45 bed boutique hotel set in 85 acres of wooded valleys within the North Yorkshire Moors National Park. The hotel offers terraced views of the landscape and across the Whitby coastline. A new extension was designed that is built against the hillside with stepped landscaped areas around the new building and an intensive green roof terrace to help blend the structure in with the surrounding gardens.The intensive green roof terrace is installed directly above a new function and dining room and required a specialised design to accommodate the additional loading and provide the necessary drainage for the turf lawn.     By utilising a multi-purpose geocomposite roof drainage board, the green roof system could be achieved to meet the project specific requirements. The ABG Deckdrain 2540S-NW20XUV product offers a lightweight option that delivers the equivalent drainage capacity of 300mm of drainage stone in a 25mm layer that weighs over a 100 times less per square metre. The lightweight drainage layer is supplied in rolls and is fast to install and move into position. The Deckdrain layer includes an integrated filter geotextile bonded to the top of the cuspated core. This prevents the growing media layer from intruding into the drainage void and filters the soil to prevent clogging. The Deckdrain is made from a high strength HDPE core that supports the 200mm deep layer of growing media required for the intensive green roof installation with deeper root systems. The underside of the product is impermeable and provides additional protection to the liquid waterproofing membrane. A green roof surface finish further helps to prolong the lifespan of the waterproofing layer and prevent UV degradation. The large grassed area on the podium also reduces surface water run-off and the grass is protected against waterlogging via the efficient drainage board layer. The shallow drainage build-up required also reduces the height of the steps onto the terrace and the associated cost of stone flags. The completed installation encompasses a 20mm Roofdrain drainage & reservoir board to support a secondary smaller sedum roof area, as well as Deckdrain layers installed for structural drainage to the surfaces around the patio slab and retaining wall areas.ABG provided a full green roof project design, installation and maintenance service for the project.

Battersea Reach, an award-winning development consists of 1,350 apartments spread over 14 separate buildings surrounded by beautiful landscaped gardens, shops and cafes. Buzon UK supplied and installed the DPH pedestal range for the composite decking and paving to many of the terraces and balconies across the 14 separate apartment buildings. The DPH pedestal system is perfect for use at roof level as they allow for 5% slope correction and can accommodate a range of services beneath floor level as well as giving excellent drainage.
