Underpinning in Strabane
The ground under Strabane and the wider County Tyrone 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.

What is the ground like in County Tyrone?
We cover Strabane and its postcode districts BT82, part of County Tyrone, with a population of roughly 14,000. Neighbouring towns we cover: Derry (14 miles) and Omagh (17 miles).
Clay shrinkage is less of a concern in County Tyrone, so other causes such as drains, poor footings or older walls are checked first. Parts of County Tyrone lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. What you mostly find across County Tyrone: market-town terraces, rural houses and post-war estates.
Signs you may need underpinning
- Cracks that keep widening after the drains have been repaired
- Movement continuing through more than one winter of monitoring
- Footings found to be very shallow during a trial pit
How much will underpinning cost in Strabane?

| Beam-and-base underpinning | £1,300 – £2,200 | per metre of wall |
| Mini-piled underpinning | £1,750 – £3,100 | per metre of wall |
| Engineer's design and building control feesest. | £705 – £2,200 | per scheme |
Which repair method suits a home in Strabane?
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
Beam-and-base underpinning
A reinforced concrete beam is cast beneath or alongside the existing footing and carries the wall onto mass concrete bases at intervals. It spreads load well across variable ground and can mean less digging than continuous underpinning along the whole wall.
Best for: Longer runs of wall or heavier loads over variable ground
What happens when we carry out underpinning in Strabane?
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 Northern Ireland
In Northern Ireland, the Building Regulations (Northern Ireland) 2012 apply and the council’s building control service approves structural work such as underpinning; minor like-for-like repairs usually need no approval. The Party Wall Act does not apply in Northern Ireland, so work to shared walls depends on deeds and agreement with neighbours.
Underpinning in Strabane: questions and answers
How much should I budget for underpinning in Strabane?
Guide prices for underpinning in Strabane start from about £880 per metre of wall, including VAT, on Northern Ireland 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 Strabane?
Yes. We take enquiries from across Strabane, including BT82, and from nearby places such as Derry and Omagh. Send photos for a free initial view and we will tell you what happens next.
Why do houses in County Tyrone crack?
Tyrone has glacial till over varied rock, with a small historic coalfield around Coalisland near Dungannon. Only an investigation can say why a particular building has moved.
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.
Does my house really need underpinning?
Often not, because most subsidence is fixed by repairing drains or managing trees and then repairing the cracks. Underpinning is justified when monitoring shows movement continuing after the cause has been dealt with, or when the ground itself is unsuitable. An independent engineer should make that call.
