Damp Proofing London South tanking systems for Basement or Cellar
In the photos above you can see the basement tanking process from start to finish.
Damp Proofing London South cellar and basement tanking systems are installed to either the positive pressure side or the negative pressure side of a substrate. Positive tanking pressure is when the hydrostatic water pressure is pushing tanking application onto the substrate. Negative tanking pressure is where the cellar and basement tanking system is installed to the oposite side of the wall and the hydrostatic water pressure will try to push the tanking application of the substrate. It is very difficult to achieve successful cellar or basement tanking on the oposite side as it demands more comprehensive specification.
During tanking process of basements and cellars internally, products such as asphalt, self adhesive membranes or liquid applied membranes all require a supporting vertical brick or blockwork lining wall, which is normally backfilled with sand & cement mix and sand & cement screed. Damp Proofing London South Cellar and Basement Tanking Systems can be applied to both walls and floors.
Cellar and basement tanking systems are like a watertight envelope. If there is hydrostatic water pressure present or possibility of high water table in the future, then floor must also be tanked to achieve the watertight integrity. If continuity is not completed, or where different systems cannot be tied effectively together, then the system will stay vulnerable to water ingress. Where continuity has not been completed, for commercial reasons at the clients request, then this should be identified for future reference. Damp Proofing London South would recommend identifying such areas as sectional tanking with liability restricted to the areas which were actually tanked.
Cementitious tanking and epoxy systems are the most traditional method of waterproofing and can be used as an alternative to cavity drain membranes in certain installations. Cementitious systems are the best for contracts where limited areas are to be treated or where drainage is very hard to achieve. These cellar and basement tanking systems can also be used with cavity drain membranes in cases where there is a flat soffit with no drainage falls or where headroom is limited.
-Single component, polymer modified cement "tanking" system for walls and floors.
-Highly effective damp proof membrane for brickwork, concrete or any cementitious substrate.
Surfaces to be treated should be correctly prepared, free from all loose materials and contaminants and be in a sound and solid condition. For application to floors products should be applied directly to the structural slab. For wall applications products should be sandwiched between sand/cement render coats. For all applications, special attention should be given to wall/floor junctions.
Fillet Seal is a pre-packed, cement based and polymer modified product for use as a floor to wall junction seal during waterproofing works when using cementitious slurry coatings and renders. Fillet Seal helps to ensure a smooth transition between horizontal and vertical surfaces which minimises the risk of leaving gaps or holes unsealed during the waterproofing works.
