CABLE GUARDS (ANGLE IRONS) AND SILICONE

Some snow melting installations require a heating cable to transition across a stress relief cut in a slab. In these locations, TRM recommends the installation of an angle iron cable guard, backfilled with silicone, to prevent the heating cable from shifting and sheering when slabs crack and shift. The cable guard (angle irons) structural strength minimizes the differential movement of the concrete across the control joint, while the silicone rubber conducts the heat away from the heating cable, preventing cable damage.

Our team of experts can help you assess the existing site conditions and intended installation to determine if extra cable protection is required for your application.
