A high-quality grouting material prevents the leaching of harmful substances and their entry into the groundwater or the soil through good environmental compatibility.

Due to its good long-term stability (against frost effects from the geothermal probe or cementitious materials in the groundwater), it ensures a good connection of the probe pipes to the surrounding soil. The incursion of surface water is prevented, thus ensuring the protection of groundwater. The use of thermally improved grouting materials increases system efficiency by reducing the resistance between the borehole wall and the probe pipes. This ensures a better heat transfer.
