The Material Store, Hayes
3 May 2017
The Material Store development is part of the £250 million regeneration of The Old Vinyl Factory in Hayes, West London, where thousands of people worked for EMI, pressing and packaging vinyl records and making everything from radio sets to bicycles.
The slabs were constructed approximately 1.5m below ground level and although the new concrete incorporated a watertight concrete admixture would have remained gas and vapour permeable. Two coats of Triton’s TWS- Fastcoat, (which can be applied effectively in ambient temperatures even when substrate temperatures are as low as 0o), therefore provided an impervious barrier which will also lower the potential risks of corrosion of the steelwork in the slabs as well as protecting the outer surfaces.
TWS-Fastcoat is a single pack, moisture curing, elastomeric resin. The membrane cures in a continuous and elastic form, as a totally adhered layer. It guarantees total water tightness and withstands minor building movements and vibrations. TWS-Fastcoat can be used as a base coat, a reinforcing layer or a top-coat. Other typical applications include podium decks, low pitch and flat roof areas with pedestrian traffic, wet rooms, lightly trafficked flooring, water channels and ponds. In green roof applications, the addition of Triton’s geotextile fleece between the two coats of TWS-Fastcoat provides an effective root barrier and waterproofing layer.
At the Material Store development, as part of the preparation for the application of TWS-Fastcoat, Triton’s Fillet Seal was applied in 25mm beads to all internal angles that eliminates 90o angles at wall/floor transitions and minimises the risk of leaving gaps or holes unsealed. It was also important to ensure that the concrete surface was clean and dust free. On porous or friable surfaces, Triton’s TWS-PU Primer should be applied before the application of TWS-Fastcoat.
The slabs will receive raised access floors over the TWS-Fastcoat layer, allowing any potential water/rain ingress to enter the drainage systems of the individual dwellings beneath the raised floor.
