Sub Slab

Sub Slab Depressurization

Any concrete basement area is considered a sub-slab depressurization area. The sump pump and nearly all cracks need to be sealed with the proper sealants to achieve the lowest radon level. In any unfinished basement, all lose items against the exterior walls need to be away from the wall so that a technician can seal the concrete gap between the floor and concrete/ block wall.
