The Concrete Mat Xpress for strength and reliability

By pairing the sturdiness and performance of the Green Cable Concrete and the simplicity of a self-adhesive backing, the Concrete Mat Xpress is the ideal choice for any installation embedded in concrete. Simply unroll over the insulation under the concrete slab or over plywood under a concrete topping and you’re done.
