Tanking / Waterproofing

Toucan Property Maintenance specialise in tanking and waterproofing – we use a cement based tanking slurry coating that seals walls or floors.

Basement Waterproofing

Basement waterproofing or tanking as it can be known, can be used to prevent rising damp above ground or to prevent water ingress below ground level. Tanking is a traditional form of cellar or basement waterproofing which would typically be found on older properties.

The method Toucan use for tanking work is to apply a waterproof coating directly to the inside of porous cellar walls to prevent moisture from seeping in. This coating does not remove the water, it simply creates a barrier.

For a tanking system to work well, the walls that the tanking product is being applied to must be well prepared.

Tanking systems also require the brickwork of the house to be stable due to the fact that tanked walls need to resist the water pressure that will build up. In older homes, preparing walls to take whatever coating is being used can be quite time-consuming, involving careful removal off old plaster, raking out old mortar, re-pointing and applying salt-neutralising products.

Waterproof coatings can be applied using a trowel or are sometimes sprayed on, with the aim of forming a bond with the masonry substrate, to create a completely waterproof barrier. Plaster can then be applied on top of these coatings.
