Treating Rising Damp through damp floors
Damp rising through concrete floors or tiles is fairly common. 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.
We offer two solutions to the problem of damp rising through existing concrete floors:
Firstly, our liquid membrane coating can be applied directly to damp floors. This method has the advantage of being extremely easy to apply and only fractionally raising the floor-level. However, it is extremely important to ensure that the floor to be treated is free from contamination.
For this reason, our most popular solution is to use our rigid damp-proofing membrane. The membrane can be laid directly onto contaminated floors with minimal preparation.
The membrane is a tough, polypropylene membrane that can be laid on top of damp concrete floors. A wide choice of flooring types can then be laid on top, e.g. screeds, particle board, laminated wooden flooring, and tiles.
Our membrane is much thicker than conventional damp-proof membranes, and is manufactured from polypropylene, making it extremely resistant to on-site damage. It’s 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 our membrane can allow new finishes to be applied to existing floors without the need to resort to expensive excavation and relaying of damp floors. The 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.
