Waterproofing & Conversions

Basement and Cellar Waterproofing Conversions

  • Are you missing out on the useful addition of living space beneath your feet due to a lack of waterproofing or best use of your cellar or basement space?
  • Do you have an existing basement or cellar that has flooded or become unusable due to ongoing dampness?
  • Would you like to convert this space into a valuable and beneficial part of your property with a basement conversion?

If you answered yes to any of these questions, Advanced Preservations can help.

Build upHere at Advanced Preservations we have a dedicated basement design and installation team, specialising in both the domestic and commercial waterproofing of below ground buildings and structures.  When waterproofing a retaining structure, a basement, or a cellar space, it is essential to get the fine details correct to ensure a reliable and successful project.  As leading specialists within the industry, we take great pride in the successful cellar tanking and renovation of hundreds of basements and cellars each year.

Our team of qualified structural damp proofing surveyors will be pleased to answer your queries and offer advice on solving your damp/water proofing problems. Where required we can carry out a survey, report our findings and submit our specification of works and costs dependent on your requirements.

Whatever the project may be, if you need us to take care of the full conversion package, work closely with a nominated Builder/Architect/Engineer team, or simply just conduct the waterproofing element for you, we can design and install a bespoke and guaranteed system according to your needs.


Whether you are looking for a basement conversion to turn an unused basement or cellar into essential additional living space, form a usable home office, create a games/media or play room, install a gym or you just need additional dry storage, we have the solution for you.

To ensure this high standard is maintained, we look at each project individually, making sure we consider and install a successful basement waterproofing scheme that will provide reliable and long lasting protection.

We can deal with all manner of specialist structural waterproofing and as no two projects are the same, we tailor each scheme to your specific requirements.
