Basement pool structures introduce higher loads and tighter movement tolerances than typical residential basements. Piling can be used to transfer loads to suitable strata, reduce settlement risk, and provide a stable foundation platform for the reinforced concrete pool and basement shell—particularly where ground conditions, nearby structures, or site constraints demand controlled performance.

Temporary works are planned and controlled through defined procedures, design checks, and sequencing. For high-risk phases such as excavation support and propping, we operate with appointed Temporary Works Coordinator (TWC) and Temporary Works Supervisor (TWS) oversight in line with BS 5975-1:2024, helping ensure changes are controlled and the works remain stable as the excavation progresses.

BS 8102:2022 sets out how below-ground structures should be assessed and designed to manage groundwater and damp risk. For a basement pool-ready shell, waterproofing design considers the environment, intended use, maintainability and risk. On our projects, waterproofing is designed by a named CSSW specialist, with detailing coordinated around joints, penetrations and construction sequencing.

The steel frame and reinforced concrete (RC) basement shell are coordinated through connection detailing, interface tolerances and load paths. This helps ensure the superstructure loads, pool loads and lateral pressures are properly transferred into the foundation and RC elements, while keeping the build sequence safe and buildable.

We specialise in basement engineering and construction—typically delivering shell & core, enabling works, structural excavation, piling/groundworks, structural concrete, and waterproofing design coordination. Where required, we also manage key compliance and site logistics so the project is ready for follow-on trades without compromising structural integrity or waterproofing strategy.
