How to tank a cellar

Tanking a cellar

Cellar tanking is the process of stopping water ingress and dampness affecting  underground cellars. Often old coal stores are present making use of below ground spaces.

Originally dampness to these locations was considered acceptable, however the increasing need and cost of space in homes has resulted in the requirement to make these areas dry, either for dry storage or to upgrade the use of the area, often making bathrooms, utility rooms and studies etc.,

To tank a cellar, firstly the existing walls needs to be prepared to remove loose material, old plasters and generally the walls and floors need making good to provide a solid surface ready to receive the chosen method of waterproofing.

Sheet membranes are relatively easy to apply however do not prevent water entry into the cellar and therefore drains, sumps and pumps will be required to discharge the water from behind the membrane.

Following the damp treatment, walls can be replastered, however consideration must be given to the correct specifications for replastering depending on the selected method of the cellar tanking.
