Soilfrac® – Compensation Grouting


Where conventional grouting technologies for void filling for foundations or structural remediation works are not suitable or the lifting of structures is required, the Soilfrac®-Method fills this gap within the range of grouting techniques.
Together with newly developed instrumentation and monitoring technologies as well as special sensors it is possible to lift structures by several decimeters in a controlled manner.

Lifting and Protection of Structures

In this process fractures are created in the soil which are filled with hardening grout. Every soil formation can be improved by multiple rounds of grouting and controlled lifting can be induced.
