How can new floors be safely installed over damp or contaminated surfaces?

With UZIN RR185.

Substrates that have, for example, high residual moisture content or contamination from oil and grease usually require laborious and expensive surface preparation. This work can be avoided by using the reinforcement underlay UZIN RR 185. The underlay has slip-resistant foam studs on the underside that separate the top covering from the substrate. Between the underlay and the substrate, there is a thin air-layer and traffic over it creates a pump-effect so that moisture can escape at the edges. High residual moisture no longer has a damaging effect on the flooring construction. As the reinforcement underlay is loose-laid, the flooring can be easily removed, leaving no residue, at a later date.
