Basement waterproofing?

The call for converting basements continues to grow in popularity as homeowners seek a cost-effective and reliable method of creating extra living space within the home. Basement waterproofing plays an essential part of any cellar conversion project as it is the key factor in eliminating all possibility of water ingress in order to protect the basement and maintain a dry, warm and healthy area. 

Being underground, a basement is more susceptible to the possibility of unwanted water ingress. The type of basement system to use is therefore an important consideration as a variety of methods are available.

Cement tanking slurry are one option for a basement tanking solution; it works by blocking water from entering a building under hydrostatic pressure. It is is vital the walls are prepared thoroughly before applying two coats the slurry onto the masonry. Once the final coating has hardened, a coat of plaster is applied to protect the tanking layer from damage in service.

One of the most effective and commonly used system is the installation of waterproofing membrane on the walls and floors of the cellar. This cavity drain membrane effectively seals the area and, behind the scenes, manages the flow of water to an exit drain; providing consistent protection against the damaging consequences of unwanted water entering the home.
