Andover based MDH Roofing & Son are specialists in GRP Waterproofing Systems. It is one of our most requested services.

GRP Waterproofing Systems – The most effective, durable and aesthetic generation of Flat Roofing – applied without the use of heat.

GRP flat roofing system has the potential to outlast the structure it is protecting (studies show 50+ years). It is the proven solution to all roofing problems.

It is formed on a new roof deck to create a solid, waterproof membrane which is fully bonded to the decking that covers the whole roof with no joins or welds. You can apply this product to any sized structure from 0.1m2 to 100m2 and beyond (providing it has an expansion joint which we can provide) this product is truly versatile and extremely hard wearing – it cannot be cut with a knife or damaged by falling debris. The product will also withstand UV exposure and extreme heat.

This is an ideal solution for balconies or roof terraces as we can offer an anti-slip finish or can offer a watertight foundation for decking or patio slabs (subject to non-cement based adhesive being used).

This product is also brilliant for lining ponds, and we have lined a couple during our time of using it. Where they have previously been unusable due to damaged or cracked base, GRP has given them a new lease of life making them fit for purpose providing a durable waterproofed liner.

GRP is also eco-friendly and fire retardant to (BS476-3:2004EXT.F.AB) and is also perfect for green roofs as it does not give off any substances that can harm the environment or create any toxic by-products.

The system comes standard in graphite grey but additional colours can be requested.

GRP is not limited to just flat roofs, it can be used and applied to pitch roofs, dormers, valleys and bay windows.

The best part about its application is that it doesn’t require a flame, which provides reassurance to the customer and results in a much safer application.
