Excessively damp structures are the perfect breeding ground for moulds which are responsible for various illnesses and are major allergens. Damp walls are also produce aesthetic defects, which degrade the structure itself.
Damp walls increase the energy demands of the overall structure of a new construction or existing house by 25 to 30%. Dry walls save energy, regardless of if electricity or gas is used.
Remediation of damp masonry structures and waterproofing are integral and important parts of the construction industry. Incorrectly installed waterproofing on existing and new construction houses alike results in damp masonry structures, and these structures need help.
our customer undercut their walls or use an injection process to break the capillary structures that connect the foundation to the walls of the damp structure. Excavation under a house or other building employs a studded mat that rests against the wall and the insertion of a drainage pipe at the bottom of the excavated trench. We do not recommend this method for our customers as it does not interrupt the capillary action along the entire length and width of the foundation. The effectiveness of this method at removing moisture is only around 10%. Another option is to insulate walls with remediation plasters or other special plasters, as recommended in building supply stores. We do not recommend this method as the water in the masonry structures contains salts and minerals that plug the pores in these remediation plasters over time, degrading their ability to perform their intended task and the moisture then reappears. Our company prefers the undercutting method thanks to its lower price, 100% effectiveness for all types of masonry structures and the very high durability and long service life of the materials that are used.
The first step to waterproofing your home is to understand the hydro geological properties of the land itself, and specifically the level of the water table, including during rainy periods. After all, the house needs to be insulated from this moisture to avoid damp walls and mould in your home.
