Optimised grouting material for geothermal probes

Quality products with high thermal conductivity

The grouting or the backfilling of geothermal probes is an important and necessary step for the secure installation and the efficient operation of geothermal systems. Besides the professional grouting, the characteristics of the material are an essential part of the process. 

Fischer Spezialbaustoffe GmbH offers the geothermal industry with the Fischer GeoSolid products a thermally enhanced and high quality grouting material, which fulfills today´s requirements in regards to safety, processability and durability.

Fischer GeoSolid® 240-HS

For sulphate bearing waters / especially for geothermal probes
Thermal conductivity > 2,40 / frost-thaw-stability according to DIN 12390/9

Fischer GeoSolid 240HS was especially designed for the grouting of geothermal probes in areas with sulphate bearing ground water and incorporates all favourable characteristics in one product. The thermal conductivity of more than 2,40 W/mK ensures an optimum connection of the probe to the ground. The great physical properties and the high mechanical resistance, guarantee a long durability and a high resistance to environmental influences.
