Thermally enhanced grouting/ backfilling material for geothermal probes
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.
Especially for borehole heat exchangers
Thermal conductivity ≥ 1,40 / also for sulphate bearing ground waters
Fischer GeoCompact was especially designed for the grouting of borehole heat exchangers. The material is also suitable for areas with sulphate bearing ground waters. All further sealing and backfilling work for well construction and civil enigeering can be done safely.
