Thermal Moisture Barrier

Excellent Moisture Barrier Under Concrete.

Tuff-Stuff provides an absolute moisture barrier and effective insulation under concrete slabs. This insulation is made up of two layers of high-strength polyethylene bubble film, giving it superior puncture-resistance; it's tough enough to walk on. Tuff-Stuff is not only easy to install, it also offers labor and material savings because it is an all-in-one radon vapor barrier and insulation product. Perfect for resisting moisture and minimizing heat loss through slabs.
