Subfloor moisture presents a number of challenges which could risk the entire flooring installation. Failing to control and manage excess subfloor moisture can result in blistering of the floorcovering or even complete failure of the flooring installation.
It is essential to measure the levels of moisture in the subfloor prior to the installation of the floorcovering and then utilise a proven system and method for managing and controlling the moisture.
The installation of a damp proof membrane in new
Prior to installing a resilient or textile floorcovering, it is essential to ensure that the subfloor incorporates an effective damp proof membrane, in accordance with British Standards BS 8203 and BS 5325, respectively.
Moisture testing is performed by measuring the Relative Humidity (RH) level within a subfloor. Where the relative humidity (RH) is above 75%, (65% where a wood floor is to be installed) the installation should not proceed as the excess moisture in the floor can result in blistering of the floorcovering or complete failure of the flooring installation. This may
result in expensive and lengthy remedial work, including the possibility of an expensive ‘rip out’, to allow the subfloor to dry naturally or apply an appropriate waterproof surface treatment.

buildings only became mandatory in 1965, the ground floor levels of buildings which were constructed before this date should be subjected to a moisture measurement test. Moreover, if a building has been compromised by a leak at some point, the floor should be tested, even if it is above ground floor level.
New buildings will incorporate a damp proof membrane, but they still remain susceptible to moisture as the drying time of a new sand/cement screed is estimated to be 1mm per day up to a thickness of 50mm. A 150mm thick concrete subfloor can take up to a year to dry out naturally. Therefore, to ensure that a concrete subfloor is sufficiently dry to receive a floorcovering, all new build projects should be tested for moisture. It is good practice to always carry out a moisture measurement test prior to any flooring installation.
