🧱 IGSHPA Grout (Silica Sand / Graphite Bentonite Grout 0.88 to 1.4 BTU/hr-ft-°F)

Thermally Enhanced Bentonite Grout Calculator

Calculate batch mix proportions and thermal conductivity for silica sand and graphite-enhanced bentonite grouts backfilling geothermal U-tube boreholes under IGSHPA: calculate thermal enhancement (increasing conductivity from standard 0.40 up to 1.40 BTU/hr-ft-°F to reduce borehole thermal resistance R_b by 40%), grout pump batch yield, and grouting contractor margins.
