The KAWO – Cap technology is a progressive trenchless technique, which aids in connecting sewer service pipes into the sewer mains. This method is based on pulling a special packer wrapped in a fabric which is soaked with quick setting resin through the sewer service pipe. After curing, a sleeve is formed in the area of the connection, ensuring leak tightness and therefore properly conducting sewage into the sewer main. The work is done with the assistance of a camera after proper washout of the piping. The KAWO – Cap technology is used to rehabilitate and repair sewer service connections of DN 150 to 250 in less than manhole-sized profiles of DN 250 to 600.
