It is essential when using below ground rooms to engage the services of a specialist to avoid issues with water penetration into your basement. Our specialist basement surveyors hold the CSSW qualification and can advise you on design, layout, building control issues and are available to answer all your basement waterproofing questions. We also have an ‘in house’ PCA Registered Waterproofing Design Specialist.

Basement Conversion

For property owners looking to improve an existing basement or convert an unconverted space, BAR Preservation can offer two separate services.  The first option is to appoint BAR to undertake the design, installation and commissioning of waterproofing systems only.  The second option is to appoint BAR Preservation to take full control of your project from inception through to design, onto construction and finishing details.

In the event a client has a builder already appointed or the builder themselves wishes to use a specialist for the waterproofing element of a conversion, we will happily work alongside the builder and other trades.

Not only will BAR Preservation undertake all the waterproofing and tanking required for a basement conversion they will also undertake all associated general building work including:

  • New flooring, wall and floor insulation.
  • Plastering.
  • Staircases leading down the basement.
  • Installing fitted kitchen units.
  • All plumbing work.
  • All electrical work.
  • Installing heating systems.
  • Installing Ventilation.
  • Providing and installing windows for natural light.

In choosing BAR Preservation, you can be assured of excellent service and a very high level of workmanship from qualified surveyors and installers. We are regularly appointed by insurance loss adjusters to retrofit waterproofing systems into properties which have experienced failure of tanking systems, some of which are often only a few years old!

BAR Preservation have undertaken basement waterproofing projects ranging from small single rooms to larger projects including swimming pools, cinema rooms and gymnasiums. Whatever your needs, we can accommodate your requirements, regardless of project size.
