Thermal Resistivity Sand

Used for underground power cable installation or Thermal Resistivity Sand (TR SAND) is a quality assured, industry leading, engineered backfill material.

Benedict Thermal Resistivity Sand (TR SAND) is a quartz based, well graded sand that offers an extremely low thermal resistivity rating of approximately 0.7Km/W, at 97% compaction of MDD and 0.0% percent moisture.

The highly compactable nature of our Thermal Resistivity Sand (TR SAND) allows our material to be tightly packed around the power cable, minimising air space, and reducing resistance of heat flow between the cable and the ambient environment. This allows the heat to easily dissipate from the cable, and gives engineers the option to potentially use a lower rating of cable when used in conjunction with Thermal Resistivity Sand (TR SAND), and benefit from the resulting cost savings to the project.

We have a proven track record in major projects including; Bango Wind Farm, Flyers Creek Wind Farm, Rye Park Windfarm & The Wellington Solar Windfarm.  Read more
