From older properties with persistent damp problems to new basement conversions, our experienced team delivers reliable waterproofing solutions built to last.


What Is Basement Proofing?

Basement proofing, also known as basement waterproofing or tanking, is the process of preventing groundwater and moisture from entering below-ground structures.

Every property is different, which is why we carry out a detailed survey before recommending the most suitable waterproofing system. Depending on the construction of your property, this may include cementitious tanking, cavity drain membrane systems or waterproof floor and wall protection.

Our aim is to create a dry, healthy and usable space while protecting your property from future water damage.

Signs Your Basement Needs Waterproofing

If you’ve noticed any of the following, your basement could benefit from professional waterproofing:

  • Damp walls or floors
  • Water ingress after heavy rainfall
  • Musty or damp odours
