What is G.R.P.?

G.R.P. Glass Reinforced Plastic (Fibreglass) a composition of resin and chopped strand matting.

G.R.P. has been around for many years, used in the construction of boats, garden ponds and adventure water slides.

Over the past thirty years, G.R.P. has been used in the building industry as an alternative to lead and bitumen felt for flat/pitched roofs, valleys and gutters.

BEFORE		AFTER

Above a typical tin/zinc lined valley, used over many years in agriculture, commercial and industrial buildings. Over the years the metal surface has badly rusted and delaminated, causing weakness to it’s structure and then allowing water to penetrate the structure within causing untold damage to the contents within the building.

Luckily this was noticed in time. The existing surface was cleaned to remove any lose materials, cracks and holes were taped and patched, before a 3 layer (1800 grams) lay up of G.R.P. lined over the existing surface, achieving new strength and making the valley watertight once again.

G.R.P. is available in a wide choice of colours and various finishes, including non-slip covering, which makes it ideal for waterproofing balconies and roof terraces.

The advantage of G.R.P. over traditional materials is that you have a product, which is flexible in application, being able to cover awkward returns and steps. It leaves a seamless, watertight joint, offering you a maintenance free finish, with peace of mind against leaks for years to come.

Fire Retardant Systems to BS476 part 3 F A.B. are also available, approved by Building Control, used where adjacent buildings are within 9 metres of the structure.

Leaking Wet Rooms are no longer a problem with G.R.P.

Unfortunately bathroom, toilets and wet rooms are often prone to leaking . The water leaks are concealed within the fabric of building; in the floors, walls and ceilings, which offen goes un-noticed, causing wet rot, leading to structural defects to supporting floor joists if not rectified.

We offer a GRP Wet Room System, which is ideally suited to waterproof sub floors prior to tiling.
