Thermal backfill

Our thermal backfill mix dissipates heat generated by underground high voltage cables.

Buried electrical cables require thermal backfill to surround the cable within the trench This dissipates the heat from high voltage underground cabling

Our thermal backfill meets thermal resistivity, thermal stability strength and flow criteria.

Does not require compaction, reducing the risk of damaging the cable jacket. Can be pumped or poured, flows readily to fill all spaces.


Backfilling underground high voltage power cables.
