Company History

Geotherm was founded in 1978 by Deepak Parmar in the Greater Toronto area of Canada.  While at Ontario Hydro Research, Deepak worked on a research project sponsored by EPRI to help design a fully automated and portable test instrument for the measurement of thermal properties of native soils, rock, high strength & low strength fluidized thermal backfills (FTBtm) and thermal grout.  Over the years, in house research and development has resulted in designing state of the art test instrument (TPA2000) and accessories (lab, field and marine thermal probes) that have long been accepted as the "industry standard".
