Non-toxic and non-shrink with a high solids content and a low-permeability factor making it ideal for ground source heat loops and safe for contact with potable ground water. A blend of thermally-conductive sand with Portland cement for a range of thermal conductivities depending on design requirements. Thermaseal Geothermal Grout also offers low-absorption with a rigid seal to prevent integration of aquifers and is made in three versions, MN Mix (BOM #121014), and 0.75 HF (high-flow) (BOM 129569).
