Basement Waterproofing


Whether you are concerned about damp problems or are working on a project that requires a below ground waterproofing or tanking system, read on for more information on how we can help.




Basement Conversion


Converting a basement into a living space or building below ground is becoming a more and more popular and cost effective way of extending a home and working with a team of specialists is essential to the success of your basement conversion project.


Where a design team for a basement conversion will usually include an architect, engineer and builder or basement conversion specialist, a revision to BS8102 now recommends a basement waterproofing specialist be included as part of that core design team.


This change signifies the importance of waterproofing contractors and the expertise we bring. We not only specify, design and install the behind the scenes waterproofing system that will keep the basement dry, we also fulfill the role of the waterproofing specialist and will form an essential part of the design team. As the waterproofing specialist, we also take on the full liability of the design and implementation of the basement waterproofing system, meaning that the property owner is better protected.


BS8102:2009 guidance advises that the waterproofing design specialist involved with the basement conversion should have:


  • An in-depth understanding of the requirements of BS 8102:2009
  • Knowledge of the waterproofing systems available and how to apply these to the situation
  • The skills to determine sources of water, how it flows through the soil and interacts with the structure
  • Sufficient structural knowledge to be able to discourse meaningfully with the Structural Engineer
  • Sufficient geotechnical knowledge to be able to understand the implications of a soil report, and to discourse meaningfully with the Geotechnical Engineer

Basement Damp


Below ground spaces are particularly susceptible to damp problems due to walls below ground being earth retaining. Often any damp proof course will have been installed above ground level, meaning cellar floors are rarely protected by the presence of any waterproof membrane.


As a result, basement and cellar walls and floors have little resistance to the buildup of water and are susceptible to penetrating damp. Unprotected basements will therefore, usually be damp to some degree and often only suitable for storage.


Other reasons for a damp basement:

  • An already installed waterproofing system failure
  • Flooding and changes to the water table
  • Sump & pump system failure


If a basement is showing signs of damp problems we advise you to get it checked.

If you are concerned about a damp basement, please contact us to discuss the potential causes and to arrange a survey inspection.
