Foundations solved.
Properties saved.
Surveyors and chartered engineers diagnosing subsidence and specifying the right repair across England, Scotland, Wales and Northern Ireland.
What we do
Six methods, one right answer
Mass concrete underpinning
Sequential excavation in short bays beneath the existing footing, then filled with concrete to transfer load to firmer ground below.
Read more
Beam and base underpinning
A reinforced beam is cast under or beside the wall, transferring weight to concrete bases founded at depth.
Read more
Mini piled underpinning
Small-diameter piles driven or bored to depths well beyond the reach of hand-dug methods, capped with a reinforced beam.
Read more
Screw pile underpinning
Steel helical piles screwed into the ground to a tested depth, then connected to the structure with brackets or a beam.
Read more
Resin injection underpinning
Structural resin injected through small ports below the foundation. The resin expands, fills voids, and stiffens weak soil.
Read more
Geopolymer foam injection
Expanding geopolymer foam injected at depth to fill voids and re-level slabs and footings.

Diagnosis first
The right call before any digging
Most subsidence does not need full underpinning. We start with a survey and an engineer's design, not a sales pitch, then recommend the lightest intervention that will actually solve the problem.
Diagnostics, design and remedial works stay in-house, so nothing falls between contractors and your insurer.

Plain answers, no jargon
Problems
Common subsidence problems and what causes them
Cracking patterns, sticking doors, sloping floors. The usual suspects and what each one tends to mean.
Costs
What changes the cost of underpinning?
Length of wall is the obvious one. Depth, access, soil, and method matter just as much.
Process
How long does underpinning take?
From first call to reinstatement, with realistic timings for each method.
