Circum - Innovative rehabilitation sleeve for trenchless sewer rehabilitation. The special feature: Damaged cracks and pipe connections are reliably and permanently sealed from the inside, without the need for earthworks. The high-quality and corrosion-free stainless steel rehabilitation collars can be installed quickly and easily within a very short time. The system is suitable for large and small diameters, as the inner sleeve adapts perfectly to the contour of the inner pipe wall. The patented external closure of the rehabilitation collar prevents any debris flowing past it from sticking to it. Installation without environmentally harmful lubricants!
