IET Forums - Soil Resistivity?

2007-6-6 · First point - we are talking soil thermal resistivity here - not soil resistivity which is a different thing. Thermal resistance is a measure of how good (or bad) a material is at being an insulator (thermal as opposed to electrical) - ie how well it resists the passage of heat - the higher the value the more it resists heat flow.
