London Basement Construction Specialists
Who Are Making Space Below Ground?
Making Space Below Ground specialises exclusively in basement construction, underpinning, waterproofing and structural groundworks for domestic and commercial clients across London and the South East.
Unlike general builders, our expertise is focused on creating new space below existing properties. From excavation and underpinning to reinforced concrete structures and waterproofing systems, we deliver carefully planned basement solutions built to last.
As Delta Membrane Approved Contractors, we install proven waterproofing systems designed to keep below-ground structures dry and protected for years to come. Our reputation is built on quality workmanship, attention to detail and reliable delivery.
