TIP OF THE MONTH: STOPGAP ISOLATOR MEMBRANE
Stephen Boulton, Technical Service Manager for F. Ball and Co. Ltd., shares tips about using a damp-proof membrane over contaminated subfloors or to preserve flooring, such as in listed buildings.
One of the most common challenges faced by flooring contractors is the need to install a damp-proof membrane in areas where subfloors are contaminated or need protecting.
It is essential that a subfloor is dry and smooth before a new floorcovering is laid. Should a moisture measurement test find relative humidity (RH) levels of 75% or above, a waterproof surface membrane must be installed.
“Ordinarily, contamination including oil
and grease could potentially damage the integrity of a new flooring project and could make the flooring installation a complicated and lengthy process.”
Stopgap Isolator Membrane is ideally suited for heritage projects where removal of the existing floor is not possible or in areas where the subfloor is contaminated with oil, grease or chemicals. The membrane has nodules on the underside to create an airspace allowing ventilation of water vapour from a damp subfloor into a dry wall or ventilated skirting, thereby allowing impervious floorcoverings to be bonded quickly and easily.
Stopgap Isolator Membrane can be used prior to the installation of a wide range of sheet vinyl, linoleum, rubber floorcoverings and bitumen backed carpet tiles.

PROVIDING A BARRIER TO
CONTAMINATION Ordinarily, contamination including oil and grease could potentially damage the integrity of a new flooring project and could make the flooring installation a complicated and lengthy process.
Stopgap Isolator Membrane can be installed over subfloor contaminants and allows contractors to create a subfloor ready for the installation of floorcoverings, without having to take time to remove contaminants including paint, oil or grease, making it particularly suited for use in refurbishments of areas such as kitchens and garages.
PROTECTING SUBFLOORS THAT
NEED TO BE PRESERVED Stopgap Isolator Membrane is also ideal for use in heritage projects where removal of the existing floor is not possible or where the floor needs to be returned to its original state, for example in a listed building such as a church. As the membrane is loose lay, the floor beneath it will not be damaged and can be restored when the new floorcoverings are removed at a later date.
Stopgap Isolator Membrane is ideally suited for fast-track projects where time required for traditional subfloor preparation is not available and provides the perfect solution for solving subfloor moisture in heritage projects or areas of contamination.
