Measures for ground improvement are carried out prior to the start of construction work to increase the load-bearing capacity of the ground locally or for larger areas. The aim is to improve the soil's mechanical properties, which must then be verified by the geotechnical expert. The soil's mechanical properties form the basis for further planning and execution of the construction project.

There is a wide range of measures and techniques available for ground improvement: soil removal and replacement, compaction and deep compaction, vibro-replacement, soil mixing, high-pressure injections, local improvement through supporting or drainage elements and others.

Regulatory framework

Improved ground is still ground and is not considered a construction product or structure within the meaning of the Building Codes of the federal states. Regulatory verification of the fitness for use and application, such as an approval, therefore does not come into play.
