Casing for buried walls: The definitive solution to moisture problems in cellars and basements

Moisture in underground spaces such as cellars and basements is caused by a variety of factors. The most frequent cause is hydrostatic pressure exerted by water in the surrounding soil, which seeks to infiltrate through walls and floors, especially if these are leaky or made of porous materials. Infiltration can also occur as a result of cracks in masonry, poor drainage of rainwater around the building, or the proximity of a water table. Without an effective barrier, water inevitably finds its way in, making the indoor environment constantly damp.

The consequences of uncontrolled humidity in a cellar or basement are far from trivial. Moisture encourages the growth of molds and fungi, such as the dreaded merula, which can not only damage the aesthetic appearance of your home through the appearance of black and white stains or powders, but also cause allergies, respiratory problems and other health problems for occupants. In terms of your home's structure, humidity can lead to wood rot, corrosion of metal reinforcements and degradation of masonry materials, compromising the integrity and structure of the building in the long term. Comfort is also affected by musty odors and an unpleasant sensation of cold and damp.

If you want to eradicatedampness in your cellar or basement over the long term, the best solution is to install a casing. This technique creates a truly watertight shell inside the treated space. At Murprotec, we always start with a precise, free moisture diagnosis. This crucial step, carried out by our qualified professionals, enables us to identify the exact source of the moisture problem and to ascertain the extent of the problem, before proposing a tailor-made solution. Our expertise in basement encapsulation is unrivalled, and our procedures are BCCA and Socotec France certified, guaranteeing long-lasting, effective protection against the risks of damp.

Murprotec' s damp-proofing treatment follows a rigorous process. Once the diagnosis has been made, if the solution is confirmed , the work begins with meticulous cleaning of the surfaces (floor, wall, ceiling) to ensure they are clean and sound. If cracks are visible, they are filled with a special mortar. Next, our technicians apply a special waterproof coating, often cement- and resin-based, in several layers to form an impermeable barrier. This highly waterproof, approved casing plaster adheres perfectly to the substrate and resists water pressure. Once the plaster has been applied, it is sometimes advisable to improve ventilation by installing VMC, air vents or dehumidifiers to ensure optimal drying and maintain a healthy environment. Thanks to this technique,walls are made morewatertight, comfort is improved, and the cellar or basement can be easily converted, enabling you to extend your living space and enhance the value of your property. If the damp comes significantly from outside, a complementary drainage system can be considered.
