Many problems which occur with floorcoverings are a result of moisture in the sub-floor, so it is essential that the floorcovering is protected from the passage of moisture from below. Moisture in sub-floors normally results from either rising damp, due to the absence or breakdown of the structural damp proof membrane, or from residual construction moisture. Advice in the Contract Flooring Associations ‘Guide to Contract Flooring’ states that types of surface damp proof membranes are available to deal with both situations, but some are only suitable for residual construction moisture. ARDEX Damp Proof Membranes protect the final floorcovering from both residual construction moisture and rising damp, and can be applied with confidence regardless of the presence of a functioning or effective structural damp proof membrane. This is likely to be the case in any building constructed before 1970, where the installation of a damp proof membrane was not a requirement of the building regulations.

F. Ball’s range of damp proof membranes provide easy and effective solutions to overcome the problem of excess subfloor moisture, allowing for early installation of moisture sensitive floorcoverings. Stopgap F76 is a one coat waterproof surface membrane which suppresses residual construction moisture in areas with relative humidity (RH) levels of up to 92%. Where RH levels exceed 92%, Stopgap F75 two-coat waterproof surface membrane can be used to suppress residual construction moisture and rising dampness. On fast track projects Stopgap Accelerator can be added to both these systems to reduce the cure time to just 3 hours. Alternatively, Stopgap Isolator Membrane can be used to provide a physical barrier to moisture. This loose lay membrane has nodules on the underside allowing ventilation of water vapour from damp subfloors into walls or ventilated skirting. Quick and easy to install, it provides the ideal solution where traditional waterproof surface membranes cannot be used due to surface contamination.

Flowcrete’s range of surface damp proof membranes, bonding agents and penetrating hardening systems can be used to solve excessive relative humidity (RH) and to restore the surface of defective screeds. Hydraseal DPM allows the immediate installation of moisture sensitive floor finishes onto concrete and cementitious screeds with a moisture content of up to 100% RH. The solvent and water free epoxy resin formulation is designed for use with the full Isocrete Floor Screed range. Flowcem is a three component, self smoothing screed which acts as a surface DPM and underlayment allowing the early installation of moisture sensitive floor finishes onto concrete and cementitious screeds which have a moisture content of up to 100% RH. Other systems include Isocrete M-Bond, a solvent-free, epoxy bonding agent for screed as a single-coat bonding agent (two-coat M-Bond Extra also provides a DPM) and PHS, a penetrating hardening system to re-strengthen and refurbish failed cement.
