Designed and delivered for safe, dry, long-lasting basement spaces under existing properties or new builds.
Basement construction is the full job: excavation, retaining structures, drainage, steel fixing, structural concrete and waterproofing. We handle the sequence in-house so nothing falls between trades.
Every site is different. Tight London plots, listed buildings, sloping gardens, party-wall conditions. We plan the dig, the access and the sequencing before any digger turns up. The site visit is the first step.
Outputs at completion: a structurally sound, waterproofed, drainage-tested basement shell ready for fit-out. Warranty paperwork and as-built drawings are part of the handover.
