...basement can be constructed by beginning with an insulated raft slab, followed by an ICF foundation wall. This provides a continuous layer of insulation separating the concrete from the ground. The result is a very comfortable and energy efficient basement, with no thermal bridging and reduced risk of mold. Basemen...
