In the rehabilitation of sewage systems is a water-resistant integration and a
flush lining of the newly drawn short pipe strand in the junction area of the shaft construction required. In any case, the shaft inlets should be freed up to a greater extent before the beginning of the refurbishment, so that the lips of the wall collar
can be bricked up easily.
Upon request, we also supply manhole inlets for pouring or excavating into manholes in the length 150 - 240 mm.
With the EPDM masonry collar, pipes can be groundwater tight through or connected to shaft walls. The collar collar is pulled onto the pipe by hand and fastened with the corresponding clamping system according to the assembly instructions.
The mounting takes place up to DA 500 mm with a screwdriver. From DA 560 mm, installation is carried out with a clamping tool.
