We offer a gravity liner solution which is fully structural, smooth and close fit, perfect for sewer and stormwater pipelines. Our liner is made from a type of modified PVC compound designed and synthesized by ASOE and can structurally rehabilitate brick, concrete, grp, reinforced plastic or corrugated metal. This is a perfect solution for pipeline rehabilitation projects, which involve host pipes that cannot be repaired by the traditional remove-and-replace method.
