Basement Waterproofing

Structural Waterproofing or Tanking as it is otherwise known is essentially water management for areas such as basements, cellars and solums.  An area in a property under ground level is susceptible to water damage due to gravity forcing water to flow down to the lowest part.

Most basements have experienced water ingress problems at some point in time. A basement is by its very nature surrounded by earth on at least one side and results in the space becoming susceptible to water pressure from below and from the earth facing side.

In these circumstances you must consider a “Tanking or Water Management” solution to stop or block the water migrating into the structure.
