Underpinning in County Tyrone
We carry out underpinning across County Tyrone, from the larger towns to smaller places nearby. Clay shrinkage is less of a concern in County Tyrone, so other causes such as drains, poor footings or older walls are checked first. Every job starts with the cause, then the repair is specified to match it.

What should you know about the ground under County Tyrone?
Tyrone has glacial till over varied rock, with a small historic coalfield around Coalisland near Dungannon.
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.
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
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 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.
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.
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.
Is it time for underpinning? Common signs
- Cracks that keep widening after the drains have been repaired
- A large tree nearby that cannot be removed or reduced
- Floors sloping noticeably towards one external wall
- Movement continuing through more than one winter of monitoring

Do you need approval 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
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. Parts of County Tyrone lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Only an investigation on site can say why a particular building has moved.
How much will underpinning cost in County Tyrone?
On Northern Ireland rates, underpinning starts from about £880 per metre of wall, including VAT. The written price depends on the extent of the damage, access and whether an engineer or building control is needed.
Will underpinning affect selling my house?
It needs explaining to buyers, but a properly documented scheme is far better than unresolved movement. Keep the engineer’s design, the building control completion certificate and any insurance paperwork. Lenders and surveyors will usually ask for these before agreeing a sale.
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.
