Basement Flooding: Effective Waterproofing Solutions

While damp proofing a house is complex, waterproofing a basement is a different ball game altogether. Known as basement tanking, there are several ways to keep an underground space dry, with the most common being a cavity drainage system.

What is a cavity drainage system?

A type C cavity drainage system comprises of 3 main components, which are as follows:

  • Cavity drain membrane – Typically made from high density polyethylene, there are studs fitted to create a wall cavity, an essential gap between the interior walls and the substrate. Water that enters this cavity is then channelled into a floor channel, where it is pumped into the drains.
  • Drainage channels – Located at the bottom of the wall cavity membrane, the drainage channels direct water into the sump area.
  • Sump area and pump – The sump area contains water, which is then pumped into designated discharge points.

With the ceiling, walls and floor all protected by cavity membrane, the basement waterproofing system is comprehensive. It takes a few days to install a cavity drainage system and all items in the basement must be removed prior to the commencement of work.

Benefits of cavity drainage system

The benefits include:

  • Reliable and efficient – A cavity drainage system offers a reliable and highly efficient solution that requires very little in the way of maintenance.
  • Minimal surface preparation – Unlike traditional basement tanking, a cavity drainage system does not involve much in terms of surface preparation.
  • Minimal stress on the structure – The system does not resist ground water pressure, which means less stress on the structure long term.

At London Damp Specialists, we are proud of our excellent reputation and to reflect that, we issue a comprehensive 30-year guarantee. There are many advantages with a cavity drainage system, which is not only very effective, but it also requires minimal maintenance. The best time to install a cavity drainage system is during the initial construction, although it can be fitted at any time.
