Frequently Asked QuestionsBasement Waterproofing FAQs --------------------------- ### What waterproofing system do you use for basements? The correct system depends on the structure, condition, and intended use of the space. We recommend the method that fits the property rather than forcing one standard treatment onto every basement. ### Can you waterproof a basement before conversion? Yes. Waterproofing is commonly carried out ahead of a conversion so the space is protected before finishes and joinery are installed. ### Do you deal with existing leaks as well as prevention? Yes. We handle both active ingress problems and preventative waterproofing where clients want a dry, dependable basement long term.
