Basement Waterproofing

As leading experts in our field, here at Quadrant Damp & Timber Treatments we use high quality equipment to waterproof basements and cellars in domestic and commercial properties throughout North and West London, including the Ealing and Hampstead areas.

Basement waterproofing, also known as tanking, is a process used to stop structures or properties built at ground level or below from leaking as a result of water pressure. Our two main methods of tanking include:

  1. Cementitious structural waterproofing
  2. Cavity drain membrane

With over 40 years’ experience caring for properties, our experts can determine which method would be most suitable for your property with a thorough damp survey. For further information about damp proofing, or to arrange a free, no obligation survey, simply contact our expert team today.

We used Quadrant for damp proofing the ground floor of our home. We found them to work diligently in getting the job done. All questions and concerns were addressed by the team. I wish to express a special "thank you" to Ellie, Paul and Rob. I can also say that both Rob and Paul cleaned up after the job and Ellie always provided a polite, professional and proficient service. I recommend Quadrant to anyone looking for damp treatment. Thank youread more

Very helpful, a professional report was done, the guy who came to see my property was on time and polite. He sent me a very detailed report explaining that the problem was condensation not damp, and how we can prevent this in the future. I contacted many other companies, some wanted to charge me for a survey, some didn't turn up and one was rude to me down the phone. I can't stress enough how pleased i was with this company's attitude, I would recommend them to anyone.read more
