Why Thermaflow™ Thermal Fill?

Efficiently dissipates heat generated by buried cables providing constant electrical power.
Predictable thermal performance enables contractors to optimize conduit capacity, trench depth, and reduce construction costs.
Allows for shallower trenches and potentially fewer conduit runs, potentially reducing excavation and materials costs.
Local mixes are pre-tested, ensuring confidence in material performance when and where you need it.

The Challenge

Underground transmission lines require a stable thermal environment. Excessive heat can cause:

derating of cable ampacity and hot spots
reduction in cable lifespan
premature cable failure to conduit

Backfill material selection needs to consider:

thermal stability
low (and accurate) thermal resistivity
self consolidation
precise spread, viscosity and flowability
local availability

To Ensure Power That Never Stops:

Think Beyond Concrete

Thermaflow minimizes the depth of burial and cost of backfill and maximizes the number of conduits and size of ducts.
