GRP Flat Roofs

GRP is a modified single ply laminate, which is cold applied in situ, to create a joint and weld free continuous high performance covering to any flat roof. A covering which can be provided in a choice of colours and which when cured is virtually maintenance fee. It can be used for domestic or commercial flat roofs, for balconies and walkways, for gutters and valleys, or to simulate lead or other traditional finishes. The versatility of GRP is demonstrated by its use in flooring applications, tanking applications and as an inert hygienic surface in food preparation areas.
GRP more commonly referred to as “glassfibre” is formed in situ by reinforcing polyester resin, which has been cured or hardened with a peroxide based catalyst with an emulsion bound chop strand mat. Once cured this forms a joint free laminate that will outlast virtually any other traditional flat roof material

GRP is a cold applied system that is ideally suited to both simple and complex structural designs and can be rapidly applied and cured to prevent water ingress, giving total protection.

High performance is achieved as GRP is made up of a combination of modified polyester base resin, emulsion bound chop strand mat and a finishing coat of pre-pigmented topcoat. When cured GRP is guaranteed to provide performance beyond that of more traditional bitumen or polymer based waterproofing coatings.

Bitumen based waterproofing systems have been used for almost 2000 years. Unfortunately the only thing that all bitumen based products have in common is how little time will they take to fail. With GRP you now have a cost effective alternative that if installed to the correct specification should easily outlast the performance of the overall flat roof structure. GRP is designed to perform.

GRP systems have been used successfully for over 20-years. They are fast becoming the preferred choice of Architects, Specifiers and Local Authorities. Only installed by highly skilled and suitably trained installers clients can be assured that GRP will continue to perform long after more traditional flat roof coatings have failed. GRP is a permanent solution for your flat roof.
