GRP fibreglass, tough and tidy

A hard, toughened surface that keeps water out and stands up to foot traffic. A cost-effective way to stop leaks for good.

Overview

GRP, short for glass reinforced plastic and often called fibreglass, gives you a lot of freedom in design. It is a cost-effective way to stop leaks into your home or business.

Once cured, GRP forms a toughened surface. With the right finish it is suitable for walkways, terraces and balconies as well as roofs.

It comes in a range of colours and finishes. As flat roof specialists, we will look at your roof and tell you plainly whether GRP is the best option or whether another system would serve you better.
