Installing Damp Proof Membrane Floor
Damp rising through concrete floor slabs is fairly common, causing damp issues on carpets and floor coverings, warping wooden floors and increasing the likelihood of low-level mould growth. The damp-proof membranes used during construction of concrete floors are often thin, and can easily become torn before they are laid, rendering them ineffective.
Apr 17, 2013 Darren explains what a damp proof membrane is. Waterproof and damp proof a concrete floor by laying a. Installing a Damp Proof. How can the answer be improved? How to Pour a Concrete Floor. Next, the damp-proof membrane (DPM). In most cases, your builder will install your floor.
In newbuild situations, it may be necessary to install a damp-proof membrane on top of a concrete slab to enable moisture sensitive floor finishes (e.g. Wooden floors) to be laid on top of the slab - enabling works to be completed more quickly than would otherwise be the case. F1 Challenge 99 02 Setups Gaming. Safeguard offer two options for the treatment of damp rising through existing concrete floors. We also offer solutions for. Drybase Liquid-Applied Damp-Proof Membranes The Drybase range of liquid-applied coatings including and can be applied directly to damp floors to create a damp-proof barrier without raising the floor level. Drybase products have the advantage of being extremely easy to apply. Should be used in situations where the cured surface needs to be trafficable.
The hard wearing nature of epoxy coatings enables the surface to be walked on without any other floor coverings being put on top, making them ideal for garages and light industrial areas. When using liquid-applied coatings such as Drybase Liquid-Applied DPM, it is very important to make sure that the surface to which they’re being applied is properly prepared.
Any significant amounts of dust, laitance or oily / greasy deposits can affect the longevity and effectiveness of the coating. The preparation can include power cleaning, grit blasting and / or acid etching. Because liquid-applied damp-proof coatings are so versatile, they can sometimes be used for other purposes such as isolating timber from masonry, or as a bonding agent for plasters and bund lining. Oldroyd Cavity Drainage Membranes.
Where a solution requiring minimal surface preparation is required, should be considered. Oldroyd Xs Slimline Membrane is a tough, polypropylene membrane that can be laid on top of damp concrete floors with minimal surface preparation. A wide choice of flooring types can then be laid on top, e.g.screeds, particle board, laminated wooden flooring. Oldroyd Xs Slimline Membrane is much thicker than conventional damp-proof membranes, and is manufactured from polypropylene, making it extremely resistant to on-site damage.
Its patented ‘X’ pattern makes it easy to cut and fold. It also allows moisture to move behind the membrane, and allows for shrinkage movement when screeds are laid on top. In refurbishment projects, the use of Oldroyd Xs Slimline Membrane can allow new finishes to be applied to existing floors without the need to resort to expensive excavation and relaying of damp floors. Oldroyd Xs Slimline Membrane protects the flooring finish from dampness as well as contaminants such as oil, gas, and acids, making it an excellent choice for factory and warehouse conversions.
Suppressing residual moisture in subfloors In subfloors with readings in excess of 75% relative humidity (RH), the use of surface membranes will suppress residual moisture, which can dramatically shorten project schedules. Bostik's damp proof membranes provide essential moisture mitigation and suppression for subfloors, helping to protect your installation for years to come. Fast-tracking floor preparation Bostik understands that flooring installers need to suppress moisture as quickly as possible before applying primers, self-levelling compounds, adhesives and floor coverings. This is especially true with commercial project work in retail outlets, hospitals and schools, where installation deadlines are critical. That is why our damp proof membranes have fast cure rates that accelerate the process, allowing the application of a full flooring preparation system faster than ever before. Smart benefits Bostik's surface membrane solutions offer many benefits, saving you time and providing flexibility across a wide range of installation projects: • Faster cure rate: enabling floor coverings to be installed earlier in construction projects • Moisture mitigation: extremely good resistance to residual moisture vapour • Versatility: suitable for all kinds of project work, from hospitals and schools to commercial and residential buildings • Professional grade: special additives provide excellent adhesion properties and one-coat systems.
