Cymcap Hot Crack [portable]

Replace erratic native trench soil with Fluidized Thermal Backfill (FTB). FTB maintains a low, predictable thermal resistivity even when completely dried out by hot cables.

: As moisture recedes, a completely dry pocket of soil forms around the cable or duct bank. cymcap hot crack

Maintain a slightly convex cap with a reinforcement of 1/16 to 1/8 inch. A convex bead has compressive residual stresses on the surface, resisting crack propagation. Replace erratic native trench soil with Fluidized Thermal
