Platon is a strong, double dimpled, 24 mil HDPE membrane. By using Platon over the concrete, an impermeable vapor barrier and air gap is created. This allows the concrete to breathe while keeping the floor dry. The finished floor is isolated from the cold concrete and becomes room temperature, not slab temperature. This keeps you warm and minimizes surface condensation and musty odors.

Don't Forget Flood ControlProducts to protect your basement!
A beautiful floor may hide an ugly reality. Even though it may look good on the surface, the reality underneath may be entirely different. Concrete floors always contain moisture. Floor coverings laid on concrete without an adequate damp-proof barrier will be affected and damaged. The results are unpleasant odors, mold, mildew and an unhealthy internal environment. A moisture barrier that does not provide air flow may trap moisture and cause problems.
Platon Flooring Protector gives you a new freedom of choice in floor covering materials. Carpet, vinyl, laminate or hardwood can be installed over Platon and OSB or plywood subfloor. On fresh concrete you can install flooring as soon as you can walk on the slab. Platon can also be installed on floors with radiant heat. If your basement is unfinished, install Platon and plywood or OSB subfloor, and frame the walls right on top of the subfloor. If the walls are damp, cover them with Platon!
