Fischer GeoCompact

The grouting material Fischer GeoCompact was especially developed for the grouting of borehole heat exchangers. 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.

The great processability of Fischer GeoCompact faciliates the grouting on site. The grout can be mixed in all commercially available mixers with the addition of clean water to a pumpable suspension. Fischer Spezialbaustoffe GmbH recommends for the mixing of grouting material for geothermal probes the mixer and injection plant MAT IEC 40.

Fischer GeoCompact complies with the current recommendations VDI Guidelines (VDI 4640, Part 2)

  • Accordance to VDI 4640
