DantoPlug is a pure bentonite pellet used in sealing boreholes and fallow wells. The use of this DantoPlug creates complete separation of the permeable layers. It can also be applied in (un)saturated soils. The DantoPlug barely sticks to your drill wall or pipes, minimizing the chance of bridging and further, the moisture content is very low, allowing it to flow easily out of the skirtbag. The DantoPlug comes in several varieties. Magnetite has been added to the super M, making it detectable in already finished boreholes, even when no borehole measurement has been performed. The Thermal is used in thermal optimization for geothermal heating systems. We recommend the DantoPlug super (8mm) for brackish/salt water. Furthermore, we also have the DantoPlug super in a smaller (6mm) version.
