Underpinning in Dungannon
Underpinning a house in Dungannon starts with proof that it is needed, not with a digger. An independent engineer looks at the monitoring and ground investigation, then chooses between mass concrete, beam-and-base or mini-piles for that particular wall and soil.

Why does the ground in County Tyrone matter for underpinning?
With roughly 12,000 people, Dungannon spans postcode districts BT71 in County Tyrone. If you are just outside Dungannon, we also cover Cookstown (10 miles), Armagh (11 miles) and Portadown (14 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. Typical buildings in County Tyrone: Market-town terraces, rural houses and 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
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.
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.
Your underpinning questions
How much will underpinning cost in Dungannon?
Guide prices for underpinning in Dungannon 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 cover Dungannon?
We do. Dungannon and the surrounding area are covered, including nearby Cookstown and Armagh. A free initial assessment from your photos is the first step.
Is the ground in County Tyrone prone to subsidence?
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.
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.
