Underpinning in Solihull
The ground under Solihull and the wider West Midlands decides how deep an underpinning scheme has to go. Where firm ground lies close to the surface, mass concrete is usually the practical choice, while deeper soft ground often points to mini-piles.

Why does the ground in West Midlands matter for underpinning?
We cover Solihull and its postcode districts B90, B91, B92, part of West Midlands, with a population of roughly 130,000. We also take enquiries from nearby Birmingham (7 miles), Kenilworth (9 miles) and Smethwick (10 miles).
Parts of West Midlands have clay that can shrink near trees in dry spells. Parts of West Midlands lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. What you mostly find across West Midlands: Victorian terraces, inter-war semis, Black Country industrial housing and large post-war estates.

Repair options we may recommend
Mini-piled underpinning
Small-diameter piles are driven or bored down to firm ground and linked by a reinforced beam or needles that pick up the wall. Compact rigs fit through narrow access, and the method reaches depths that would be impractical to excavate by hand.
Best for: Deep soft ground, tree roots, or restricted access
Mass concrete underpinning
The traditional method. Short sections under the wall are dug out in a set sequence, usually about a metre at a time, and filled with concrete before the next section is opened. It suits moderate depths and good access, and it needs little specialist plant.
Best for: Shallow failures on firm ground found at moderate depth
What to expect when we carry out underpinning
Engineer’s investigation
An independent chartered structural engineer studies the monitoring results, trial pits and soil tests, then decides whether underpinning is needed and which method suits. We can arrange the engineer if you do not already have one.
Excavation and concrete
Work runs in the sequence the engineer sets so the wall is never left unsupported over a long length. Building control inspects the excavations before concrete goes in, and each section is dry-packed tight to the footing above.
Crack repairs and handover
Once the new foundation has cured, cracks are stitched and repointed, inside walls are made good, and paths or patios disturbed by the dig are reinstated. You receive the building control completion paperwork for your records.
Rules for underpinning in England
In England, underpinning and other work that alters or strengthens a wall or foundation is building work under the Building Regulations (Part A, structure), so building control approves and inspects it. Like-for-like repairs often are not, and we tell you which applies before a price is agreed. Work to a party wall, or excavation close to a neighbour’s foundations, can also need a notice under the Party Wall etc. Act 1996.
Your underpinning questions
How much should I budget for underpinning in Solihull?
Guide prices for underpinning in Solihull start from about £1,000 per metre of wall, including VAT, on West Midlands rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Can you survey a property in Solihull?
Yes. We take enquiries from across Solihull, including B90, B91, B92, and from nearby places such as Birmingham and Kenilworth. Send photos for a free initial view and we will tell you what happens next.
Why do houses in West Midlands crack?
The West Midlands is mostly Mercia Mudstone and glacial till, with the South Staffordshire coalfield under much of the Black Country, where shallow coal and limestone workings are recorded around Dudley, Tipton and Walsall. Only an investigation can say why a particular building has moved.
Which underpinning method is best?
The right method depends on how deep firm ground lies, the load on the wall and the access. Mass concrete suits moderate depths, beam-and-base spreads heavier loads, and mini-piles reach deep soft ground or work through tight access. The engineer chooses the method from the site investigation.
Can you underpin only part of a house?
Yes, partial underpinning of one corner or one wall is common, though the engineer must think about the junction with the unstrengthened part. A sudden change in foundation depth can cause new cracking, so the scheme may step down gradually or include a movement joint.
