The Process 

The steps of the process are as follows:

Consultation Survey

The process would begin with an initial consultation survey at your property to discuss the project. The aim of this is to meet the people who will be completing the project and discuss your options to gain a quote report and specification.

Structural Waterproofing

It is essential to completely waterproof your basement before the project begins, as well as ensuring the conversion remains water-resistant one completed. The type of structural waterproofing can depend on the project itself. 5 of the main categories we offer are:
  • Cementitious Tanking
  • Cavity Drainage
  • Sprayed Membranes
  • Bonded Sheet Membranes
  • Sprayed Concrete
The initial consultation survey will gauge which Structural Waterproofing is appropriate for your project. Our sister company Watertight Homes also offer a range of other Waterproofing services, including:
