Waterproofing Surveys

The cost of basement construction depends on several factors, including the size of the basement, the ground conditions, the intended use of the space, and the waterproofing system required. Every project is unique, so we recommend arranging a professional survey, where one of our experienced surveyors can assess your property and provide a detailed, no-obligation quotation tailored to your requirements.

In many cases, basement waterproofing alone does not require planning permission. However, basement construction, excavation, or significant structural alterations may require planning approval and Building Regulations compliance, particularly in certain London boroughs or conservation areas. We can advise you during your survey and help you understand any permissions your project may require.

The duration of a basement waterproofing project depends on the size and complexity of the work. Smaller waterproofing installations can often be completed within a few days, while larger basement construction or full structural waterproofing projects may take several weeks. Following your survey, we’ll provide a clear project schedule so you know exactly what to expect.

There is no single waterproofing system that is suitable for every property. The most effective solution depends on factors such as the construction of the building, ground conditions, water ingress risk, and how you intend to use the basement. Our experienced surveyors will assess your property and recommend the most appropriate BS8102-compliant waterproofing system, whether that’s a Type A (barrier protection), Type C (cavity drain membrane), or a combined system for maximum protection. We only install proven products from leading manufacturers, including Delta, KÖSTER, and Sika.
