Sealing device for sewer walls

摘要

The device uses shuttering sections made of elastically expandable material, which are placed next to wall section to be repaired. The shuttering supports and forms a hardening sealant, which is applied to the space between it and the wall. The sealant forms sealed wall sections, after the shuttering has been removed. At least one of the shuttering sections consists partially of a multilaterally elastically deformable electrically conductive material. This is supplied with electrical energy to heat the shuttering.
