Structural sealing

Manhole rehabilitation
Sealing tears, shaft ring joints, pipe connections

Leaks in manholes are more likely to occur in shaft ring joints. Tears often form in a vertical direction due to ground movements. Leaks can also occur in the connection area of the shaft. Schwalm Kanalsanierung repairs these leaks with two-component resin based on PU (Spesan). A corresponding special vehicle, an injection trailer, is available to our specialist technicians for carrying out this work.
