Underpinning in Omagh
Before any underpinning goes ahead on a Omagh property, building control has to approve the design and inspect the excavations. Where the wall is shared, party wall notices may be needed too in England and Wales, so allow time for paperwork before the dig.

How do local ground conditions affect underpinning in Omagh?
Postcode districts BT78 cover Omagh, a County Tyrone town of about 21,000 people. Nearby, we also cover Strabane (17 miles), Enniskillen (22 miles) and Cookstown (22 miles).
Shrinkable clay is less common in County Tyrone than in south-east England. 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.
Guide prices for underpinning in Omagh

| 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 |
Methods for underpinning
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
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

Design and approvals
The engineer produces drawings and calculations. We make the building control or building warrant application, and party wall notices are served where the law requires them, before any digging starts.
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.
Symptoms that point to underpinning
- A large tree nearby that cannot be removed or reduced
- Movement continuing through more than one winter of monitoring
- One corner of the house visibly lower than the others
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.
Frequently asked questions
What is the price of underpinning in Omagh?
Guide prices for underpinning in Omagh 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.
Do you carry out underpinning in Omagh?
We do. Omagh and the surrounding area are covered, including nearby Strabane and Enniskillen. A free initial assessment from your photos is the first step.
Does the ground around Omagh cause cracking?
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.
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.
Can I stay in my house during underpinning?
Most people stay at home during external underpinning, because the digging happens outside along the wall. Expect noise, restricted access to that side of the house and some dust. If the work has to be done from inside, through the floor, moving out for part of the job is sometimes advised.
