I have been specifying and installing Delta products as waterproofing solutions for many years. In my experience only a small number of suppliers are true waterproofing experts, Delta being there at the top. As a waterproofing expert myself, I specify and install a wide range of solutions as I deal with a broad spectrum of problems and find that Delta’s approach of working with me ensures that my clients have a logical, economical solution to their problems.

I would like to let you know how fantastic one of your team was today. Georgia explained to me in detail which system I need to use to waterproof my basement, she explained how it works and then followed up with an email explaining it all to me with product details and prices as well. She could not have made it any easier. I now understand what needs to be done and fill armed with the correct information to be able to do this. Thank you Georgia and Delta Membranes.

We have been very impressed by Delta Membranes. They have a huge range of basement waterproofing products. Their technical staff are very knowledgeable and helpful. Their technical documents are clear and easy to use. Also they are very consistent with their costs, this means we can quote on a project safe in the knowledge that prices for their materials haven't risen from an initial discounted rate when we are awarded the work a few months later. Very happy.

I have been dealing with Delta Membranes now for a number of years. Their expertise and knowledge is second to none, they really can't help you enough and their advice and on all projects has put me and my company in a great position with my clients.
Delta membranes will even come to site and give a detailed technical specification to hand to the… client.
They have a great delivery service and if required you can even collect from their warehouse for the urgent jobs.
I really cannot praise the team at Delta membranes enough.
Keep up the good work Delta Membranes.

Excellent waterproofing products including specialist pump systems. Preferred by out client's. The Koster range is just as good and delta offer good training and onsite backup. Our installers have been trained in installing the MaxxConnect range at the HQ.

Detla's customer service is great, they answered all the questions i asked them and gave me facts that i did not know about my basement refurbishment. Mark Davison is always a great help with any technical assistance we require
I would definitely use this company again and i have recommended them to several of my friends.

My wife and I want to share the terrible experiences we have had with the Damp Proofing Industry and a PCA Member so that others can become aware and avoid such misery and the potential loss of £5000 + VAT and destroying our lovely house in the process. Last year, we purchase our lovely Victorian house built of beautiful yellow stock bricks in… Wimbledon South West London for a very considerable sum that required our entire life’s savings to be invested to meet the deposit requirements of the lender. The buying process required us to conduct a “Timber and Damp” Survey

Their membranes are the best in the market along with the drainage & sump pumps.
The Koster products they sell are good too, especially the KB Flex 200.
The technical team are very helpful and are always available. They not only give me advice but they get involved in the design and attend meetings to support when needed.
