Effective basement waterproofing is fundamental to creating safe, dry and long-lasting underground spaces. Basement Structures North designs and installs engineered waterproofing and pump systems as part of high-end basement construction projects across Northern England.

BS 8102:2022 Compliant Basement Waterproofing

We deliver fully engineered basement waterproofing systems designed in accordance with BS 8102:2022, the British Standard for protection of below-ground structures against water ingress. Every waterproofing strategy is designed by a named CSSW (Certificated Surveyor in Structural Waterproofing) specialist, ensuring suitability for ground conditions, hydrostatic pressure and intended basement use.

Our approach typically incorporates maintainable cavity drain membrane systems, often combined with structural waterproofing measures where appropriate. This dual-layered methodology provides resilience, redundancy and long-term performance for luxury residential basements, listed buildings and complex new-build projects.

Sump Pumps, Drainage & Ongoing Protection

Sump and pump systems form a critical part of modern basement waterproofing design. We specify and install high-performance pump systems, including dual pumps, battery backups and alarmed controls, ensuring reliability even during power outages or extreme weather conditions.

All systems are designed for accessibility and long-term maintenance, safeguarding the basement structure and internal environment for decades to come. This is particularly important for high-value properties across Cheshire, Yorkshire, the North East and the wider North of England.
