GRP (Glass Reinforced Plastic) is widely used throughout industry due to it being cost effective, highly durable and flexible and has numerous uses. GRP is an excellent lining system compared to coatings such as epoxies and urethanes, due to the way the system is applied and the thickness in which it is applied.

Our GRP lining system is applied in sheets rather like wallpapering and is strong enough to bridge cracks and even large holes. Epoxies (which are generally applied at 0.5mm) are not able to provide such coverage. Simplistically have you ever tried to paint over a hole in the wall at home? It cannot be done, you have to fill the hole first.

Our 3mm thick GRP system is used for bund linings as standard but normally applied to tank linings at 6mm thick. This can be increased to any thickness to try and create an inner tank that can be completely autonomous of the original. 

This level of reinforcement is not possible with coatings such as epoxies etc. We specify GRP for 99% of our bund linings for the reasons above and it will also remain flexible enough to move with the general expansion and contraction of the bund or the tank.

The standard application process of our GRP lining system is as follows:

1. Grit blasting is normally carried out to the standard required for the application.

2. All prepared areas will be primed with the specified resin.

3. CSM (Chopped Strand Mat) is applied in layers to the thickness required.

4. A chemical resisting tissue veil is applied to improve chemical resistance and also prevent pin holes.

5. A resin wash which is a combination of resins, is applied to all areas. The resin wash is pigmented to the required colour, once cured it leaves a smooth gloss finish. It is sanded to remove any irregularities and any dust is removed.

6. A top coat is then applied to finish the lining system. The lining system is strong, durable, flexible chemical resistant and has a seamless, ceramic like finish. Implementing the correct resins for the
application, the GRP lining system is the long-term, cost effective answer for a wide range of industrial containment processes.
