What is the ground like in Merseyside?
With roughly 25,000 people, Newton-le-Willows spans postcode districts WA2, WA3, WA12 in Merseyside. Nearby, we also cover Ashton-in-Makerfield (3 miles), Leigh (5 miles) and St Helens (5 miles).
Merseyside has a mix of ground, with clay in some places and firmer rock in others. Parts of Merseyside lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Typical buildings in Merseyside: Victorian terraces and villas, inter-war council estates and post-war semis.

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.
Fixed written price
With the design in hand we confirm a fixed price in writing, setting out the method, the length of wall, access arrangements and the making good. For insurance work we can price to the loss adjuster’s or engineer’s schedule.
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.
Symptoms that point to underpinning
- Footings found to be very shallow during a trial pit
- One corner of the house visibly lower than the others
- Floors sloping noticeably towards one external wall

Methods for underpinning
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
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
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.
Frequently asked questions
How much will underpinning cost in Newton-le-Willows?
Guide prices for underpinning in Newton-le-Willows start from about £960 per metre of wall, including VAT, on North West rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you cover Newton-le-Willows?
We do. Newton-le-Willows and the surrounding area are covered, including nearby Ashton-in-Makerfield and Leigh. A free initial assessment from your photos is the first step.
Is the ground in Merseyside prone to subsidence?
Merseyside is mostly sandstone with glacial till on top, with soft coastal deposits in Sefton and the Lancashire coalfield extending under St Helens and parts of Knowsley. Old docks and industry left made ground in places. Only an investigation can say why a particular building has moved.
Do I need to tell my neighbours about underpinning?
In England and Wales you usually do. Underpinning a party wall normally needs two months’ notice, and excavating near a neighbour’s foundations needs one month’s notice under the Party Wall etc. Act 1996. Scotland and Northern Ireland have no equivalent Act, but agreeing the work in writing still helps.
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.
