Many London homes have a basement or cellar and with such a wet climate we have here in the UK, damp proofing is an essential service to keep moisture at bay. Underground living space is at high risk of moisture penetration, as all sides are under threat from damp in the ground, which demands cutting-edge waterproofing solutions that keep the space dry and well ventilated.
Basement tanking
This is a term that refers to using water-resistant cement that is applied to the walls, ceilings and floors to completely waterproof an underground space. Damaged plaster is removed and the substrate is prepared for the special cement, which is applied in several layers, with a final 5mm skim. Floor screed is also water-resistant, as well as ceilings; a popular solution to keep basements and cellars dry, we at London Damp Surveys offer the best basement surveys in London by experienced damp inspectors who have seen it all.
Preparing the substrate
This is the key to successful basement tanking; once the walls have been prepared, water-resistant cement can be applied; a total of 3 coats ensures an impenetrable barrier. Of course, each basement is unique and if the ground contains clay, water retention might be an issue. The best time to waterproof a below-ground space is during construction, although it can be done at any time; we regularly inspect properties where water damage has already occurred, which means a lot of waste has to be removed. Things have to be dried out and that might require industrial dehumidifiers; we offer an accurate assessment regardless of condition.
Cavity drainage system
This is a state-of-the-art system that waterproofs basements and cellars completely, trapping water and directing it to designated drainage points. The cavity membrane is fitted to the walls using studs to create a space between the substrate and the interior walls, this cavity collects water, which is directed into the floor channels, into a sump area and ready to be pumped away to designated drainage points. Installing such as system is a complex project; careful planning is essential and that starts with a basement survey to establish the source of moisture and the natural drainage. A basement must be completely cleared prior to waterproofing and a large area might take as long as a week to complete; a multi-stage process that results in a waterproofed space that is adequately ventilated.
