Waterproofing is one of the most important decisions in any basement project. It must suit the structure, the site conditions, the intended use of the space and the long-term plan for maintenance and resilience.

Waterproofing Designed Rather Than Assumed

Our waterproofing strategies are designed to BS 8102:2022 by a named CSSW specialist. We assess the project context, groundwater risk, structure type, maintainability requirements and performance expectations before selecting the most appropriate protection approach.

That may include Type A, Type B or Type C measures, or combined protection where the risk profile makes that appropriate.

Sump Pumps, Drainage and System Resilience

Where a cavity drain system is used, sump chambers, pump selection, alarms, backup resilience, maintenance access and drainage routing all need to be planned properly. The wrong decisions here can undermine an otherwise well-built basement.

We therefore coordinate waterproofing closely with MEP and safety systems, service access and future operation, whether the project is shell and core only or a fully finished basement environment.

Waterproofing That Supports the Life of the Basement

Technical design with future maintenance in mind

A waterproofing system is only as good as its integration with the surrounding design and build. We therefore treat it as a core part of the basement package rather than a bolt-on trade item.

That is essential for premium homes and high-value developments where the basement may contain major leisure, living or service spaces below ground.

Basement Waterproofing & Pump FAQs

Because waterproofing strategy needs informed assessment of site risk, structure type, intended use and maintainability rather than a one-size-fits-all specification.

Not all basements do, but many Type C cavity drain systems rely on sump pumps to manage collected water effectively.

Yes. In some cases combined protection provides greater resilience and is the most suitable response to the project risk profile.

Yes. Drainage runs, service access, wall buildup, maintenance considerations and plant locations can all affect the finished design.

Yes. Waterproofing is integrated across structural construction, fit-out and completed basement room delivery.
