We design and manufacture GRP manholes and manhole covers as per project needs. The manholes are primarily used in sewerage projects and can be manufactured in diameters up to 4000mm. GRP manholes are produced using the same filament winding technology guaranteeing sufficient mechanical strength to bear both external (hoop) and internal (axial) loads and are fully corrosion proof. They have excellent durability and can be safely serviced and maintained.
