We deliver a rigorous testing, commissioning and handover process to ensure every basement performs exactly as designed, with full compliance, clarity and confidence for our clients.

Why testing and commissioning matter in basement construction

Luxury basements incorporate complex structural systems, waterproofing strategies and mechanical and electrical installations that must work together flawlessly. Testing and commissioning is the final technical safeguard, verifying that every system performs safely, efficiently and in line with the approved design.

At Basement Structures North, testing and commissioning is not an afterthought. It is an integral stage of our design and build delivery, ensuring compliance with BS 8102 waterproofing standards, relevant British Standards and building control requirements.
