A concrete floor can take in a lot of water and give it back very slowly. Lay new flooring on a slab that is still wet and the floor lifts, smells or grows mould underneath.
Water in a slab dries upwards and out through the surface. If that surface is covered by vinyl, laminate, tiles or carpet, it can't escape. As a rough guide, a screed dries at about a millimetre a day in good conditions, so a thick screed soaked right through can take weeks. Underfloor heating pipes and insulation below the screed complicate it further.
Floor fitters and insurers both want the job finished, but new vinyl or engineered wood on a wet slab often fails within months. A final reading on record protects you if the new floor lifts later. For tiled floors, see tiled floors. For timber floors, see timber floors.
For what drying and the repairs after it usually cost, and what insurance tends to pay, see our water damage cost guide.
Mould starts growing within 24 to 48 hours of a leak. The sooner drying starts, the less damage and the lower the cost.
Call 01482 736003From several days for a surface soaking to several weeks for a deep screed. The floor covering has to come up for it to dry at all.
Not until readings confirm the slab is dry. Flooring laid on a damp slab often lifts or grows mould underneath.
Rarely. Most slabs dry in place with the right equipment and time.
It can help drying once checked and working, but the pipes and insulation under the screed need care. We check them before using heat.
