Loosened or deformed mine workings can be restored to a safe operating condition with the help of injection technology.
The focus is on the stability of roadways, roadway branches, and manholes.

To achieve this, the loosened and no longer load-bearing rock is hardened and consolidated using (micro)cement-containing suspensions, polyurethanes, or silicates.
The application varies depending on the requirement. This can be done in one, two, or three series with different distance levels near the cavity and different pressures.
Injection work can be carried out either as a planned operation or because of sudden critical situations.

Anyway – however you decide to solve any underground problems – the experience and reliability of the F.Willich products will be your guarantee of success.
