Luxury basement construction demands more than completion — it requires long-term assurance. Our warranties and aftercare services protect your investment well beyond handover.

Comprehensive Basement Warranties

Every Basement Structures North project is delivered with clear, robust warranties covering structure, waterproofing and design responsibility. We operate to BS 8102:2022 waterproofing standards with systems designed by a named CSSW specialist, providing assurance against water ingress in the most demanding ground conditions.

Our warranties reflect the quality of our engineering-led approach — from reinforced concrete structures and temporary works design under BS 5975-1:2024, through to certified installation and documented commissioning.
