Depending on the repaired structure type, mode of failure and purpose of activities, hermetic chambers of different shapes and sizes are applied. The problems of chamber sealing on the pile and problems of loads transfer from the chamber to the structure are solved in different ways.

Hermetic chambers have been designed to perform repair works on single, group, vertical, raking piles as well as on piles of different cross-sections and depths of working zone. This special equipment is the intellectual property of GT Corporation and is protected by patents.
