Compaction grouting has been used for the successful rehabilitation of sinkholes for many years. We specialise in this grouting method, specifically to complement land rehabilitation via dynamic compaction.
Compaction grouting entails drilling a small diameter hole into the cavity, and then injecting a low strength grout under pressure in order to displace the wad and fill the cavity with grout. We have successfully rehabilitated over 80 cavities using this method.
Our services extend to any type of grouting or void filling, and, together with our design team, we establish appropriate solutions for our clients project-specific geotechnical requirements.
