Water damaged vinyl flooring a problem on concrete and wood substrate. Generally speaking vinyl flooring won t be damaged by normal amounts of water on its surface and it shouldn t be damaged by occasional dampness on the concrete slab below. So it does happen. So moisture came up through the cracks in the slab and caused the vinyl flooring to mildew.

The result was water damaged vinyl flooring. Vinyl flooring can either be glued to the subfloor or it can float on top of it and either way moisture underneath it causes problems. For installation of vinyl flooring you need a smooth even surface for the underside of the flooring to achieve the best contact for adhesion. However allowing excess moisture to leave the slab after it s poured is crucial to a successful flooring installation.

Installations in wet rooms should also include measures to ensure that the seams and perimeter of the floor are well sealed to prevent moisture getting under the luxury vinyl onto subfloor below.

Once the slab is poured the excess moisture must leave the slab in order to strengthen the concrete bond. A concrete floor with a too high moisture content can wreak havoc on a vinyl floor.
