How we waterproof basements
Basement waterproofing (also known as cellar tanking) can be done in a number of ways.
Most commonly tanking membranes for basements are used to create the barrier. Whilst this method of waterproofing does not remove water, it creates a barrier, stopping the water and moisture from seeping in. It is important that the brickwork is in a stable condition, as remember cellar & basement tanking just creates a barrier to the stop the water penetrating the basement, poor brickwork won’t be able to handle the water pressure that builds up.
It is often necessary to add a sump pump to remove water that collects beneath the cellar (see also basement pump servicing).
It can be sometimes be done through the application of a waterproof coating directly to the walls, floors and sometimes the ceiling of the basement.
Where use is appropriate, we may cure leaks by the use of resin injection, creating a ‘curtain wall’ on the outside of the structure to keep water out. We will assess and implement the best technique to stop water entering/exiting the structure using pressure injected materials.
