Before moisture sensitive flooring is laid on a concrete base it is necessary to ensure any excess water from construction is dissipated.
The concrete is tested to measure whether the moisture level of the concrete has reduced to a value where flooring can be safely laid. The relative humidity of a concrete floor can be checked in accordance with BS8203:2001 (box method) or using the Protimeter humidity sleeve method.
The basis of the test is to use a hygrometer or probe to measure the relative humidity of a pocket of air entrapped between an impervious thermally insulated housing and the surface of the screed or concrete base. Sufficient time is allowed for the moisture equilibrium to become established between the pocket of air and the base.

We can carry out relative humidity tests to see if the screed is dry enough to receive resilient floor coverings.
