When is underpinning required?

Underpinning is required when a building’s foundations are not strong enough or have been compromised. Common reasons include subsidence, new basement construction, extension works, or nearby excavation.

What underpinning methods do you use?

We carry out a range of methods, including mass concrete underpinning, beam and base systems, and mini-piled underpinning. The best method is chosen after a site survey and the engineer’s design.

Is underpinning disruptive to my property?

No. Underpinning is completed in carefully planned stages called bays. This allows the structure to remain stable throughout the works while keeping disruption to a minimum.

Do you provide engineer’s drawings and method statements?

Yes. All underpinning projects are supported with full structural engineer’s drawings, calculations, and method statements, ensuring compliance with building control and safety standards.
