Frequently Asked Questions

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.

Yes. We install high-quality waterproofing systems from leading manufacturers such as Delta, KÖSTER, and Sika, following BS8102 standards for below-ground waterproofing. Our waterproofing systems are fully guaranteed, giving you confidence that your basement will remain dry and protected for years to come. We’ll explain the guarantees available during your survey.

We provide basement construction and structural waterproofing services throughout London, Kent, Surrey, Essex, Sussex, and the surrounding areas. If you’re unsure whether we cover your location, simply get in touch and our team will be happy to help.

Yes. We regularly waterproof existing basements, cellars, and vaults, whether they’re affected by damp, water ingress, or you’re planning to convert the space into a dry, usable room. Every property is different, so we carry out a professional survey to identify the cause of the problem before recommending the most suitable waterproofing solution. Our systems are designed to provide long-term protection while complying with BS8102 standards for below-ground structures.

With over 50 years of experience, Universal Basement Waterproofing has designed and installed waterproofing systems for properties across London and the South East. Our experienced surveyors design BS8102-compliant waterproofing solutions using trusted systems from Delta, KÖSTER, and Sika. From initial survey through to installation, we focus on delivering long-lasting, fully guaranteed waterproofing solutions tailored to every property.

We aim to arrange surveys as quickly as possible, subject to availability. During your survey, one of our experienced waterproofing specialists will assess your basement, discuss your requirements, identify any issues with damp or water ingress, and recommend the most suitable waterproofing solution. You’ll then receive a detailed, no-obligation quotation for the work required.
