Foamfit underground drainage pipes are essentially multilayer pipes which have outer and inner layers of conventional PVC and middle layer of foamed PVC. Outer and inner layers are designed to take the load and middle layer of foamed PVC gives firmness and maintains the shape of the pipe under load. This also reduces total weight of pipe and makes it light in weight when compared to solid wall PVC pipes. Foamfit pipes are manufactured as per European and International standards for drainage and sewerage.
