GEOTECHNICAL BOREHOLES AND
Some boreholes require the use of a pumpable bentonite-based sealant. These will typically be geotechnical boreholes with a very small diameter.
In this case, you can use the DantoCon Cem products to plug or renovate new or existing boreholes.
These powder products are easy to handle and easy to pump. After pumping, they cure slowly, forming a dense material that is resistant to erosion and environmental impacts.
SEALING GEOTHERMAL BOREHOLES
When a geothermal borehole is to be sealed, the sealing material is usually required to have high thermal conductivity.
DantoCon Thermal C2L is a new, specially developed material that has an increased capacity to conduct heat from the soil to the geothermal installation. This bentonite-based material comes in powder form, ready for mixing with water so it can be pumped.
During development, we focused a great deal on the actual pumping, and on all the handling involved in the mixing and pumping process. The result is a material that is easy to work with. Proper mixing gives you a liquid material with a homogeneous consistency and no aqueous phase – ready for pumping.
