Platon Stop

Platon Stop provides an effective, single application damp proof underlay for wood and laminate floors laid on concrete. It’s equally effective for renovation or new build projects and the tough polypropylene membrane can be laid directly onto a new concrete slab as soon as it is dry enough to walk on. With three times the water vapour resistance than film membranes, it eliminates the need to install a foam underlay. Construction height is only 2.5mm.

Depending upon the moisture content of the floor, Platon Stop is either fixed with damp resistant adhesive tape or a butyl rubber strip. The wooden flooring material can then be installed immediately.
