GRP is a composite material which is made of resin and glass. It’s extremely lightweight and strong, which makes it extremely desirable in the field of architecture, construction etc. GRP Lining is the process of applying GRP/FRP on different surfaces, which primarily prevents leakage and absorption both inward and outward in RCC Tanks. As a result, it protects the stored liquid from fungal and algae contamination ensuring the intended quality for a long time.
