On-site consultation
The aim of our free on-site consultation throughout Switzerland is to assess the settlement damage to your house, recommend measures to repair the damage, and, if you wish, provide you with a competitive quote for PUR injection into the building ground.

Stopping building subsidence
The most efficient method for stopping building settlement is to stabilize the ground using PUR injections. This involves injecting foaming polyurethane into the foundation subsoil at several different depths, thereby restoring the settlement-free load-bearing capacity of the ground.

Get your house back on track
Pressing polyurethane into the ground beneath the concrete floor slab increases its volume, allowing the house to be lifted at specific points once a certain ground pressure is reached.

Increase ground bearing capacity
Increasing the load on the structure increases the soil pressure under the foundation, which can lead to settlement. PUR injection into the subsoil increases the load-bearing capacity to such an extent that the additional load on the structure is borne by the subsoil without settlement.

Seal leak in excavation pit wall
PUR injections are used to seal gaps and unwanted leaks in building foundation walls against pressing groundwater. The process is also suitable for creating sealing walls and floors, so that, for example, in existing buildings, pits for new elevator shafts below the groundwater level can be excavated and concreted without a special excavation wall and only with open water drainage.

Sealing Arteser during geothermal drilling
When sinking geothermal boreholes, there is a risk of an artesian well, in which pressurized groundwater rises from the depths of the borehole. By injecting foaming polyurethane at three different depths around the geothermal probe borehole, a three-stage sealing collar is formed around the geothermal probe in the injection area, which prevents water from flowing around the seal in the borehole and permanently stops the flow of water rising from the depths.
