Type A basement waterproofing also known as tanking, it is an externally or internally applied barrier system applied to the walls and floors of the structure that can withstand ground water from entering the building under pressure. There are numerous products and methods for applying Type A waterproofing systems including sheet membranes, multi-coat renders, crystalline slurries and bitumen based coatings. A thorough assessment of the structure must be carefully assessed at design stage to ensure its suitability. This system requires the structural elements of the building to be strong enough to withstand ground water pressure.

Being below ground, basements and cellars are susceptible to groundwater being forced into the structure under pressure. Factors such as type of structure, depth of the structure, the makeup of surrounding soil and location of the structure all play a part in how much dampness or water ingress is experienced by the basement or cellar during the course of its lifetime. The types and levels of basement waterproofing are just as numerous as the causes of dampness and it is essential that all factors are taken into consideration when designing the waterproofing system.
