Underpinning in Crieff
Before any underpinning goes ahead on a Crieff 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.

Why does the ground in Perth and Kinross matter for underpinning?
Postcode districts PH7 cover Crieff, a Perth and Kinross town of about 7,500 people. Neighbouring towns we cover: Perth (16 miles), Alloa (18 miles) and Stirling (18 miles).
Shrinkable clay is less common in Perth and Kinross than in south-east England. Ground movement here is more often linked to soils, drains and trees than to mining. Typical buildings in Perth and Kinross: Sandstone town houses and tenements, rural cottages and post-war estates.

How we usually approach 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
What happens during underpinning, step by step?
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.
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.
What to look for before calling about underpinning
- Cracks that keep widening after the drains have been repaired
- Footings found to be very shallow during a trial pit
- Movement continuing through more than one winter of monitoring
Rules for underpinning in Scotland
In Scotland, underpinning and other structural alterations generally need a building warrant from the council’s building standards service before work starts, and a completion certificate at the end; small like-for-like repairs often do not. There is no Party Wall Act in Scotland; shared walls are covered by title deeds and, for flats, the Tenements (Scotland) Act 2004.
Questions about underpinning in Crieff
What is the price of underpinning in Crieff?
Guide prices for underpinning in Crieff start from about £950 per metre of wall, including VAT, on Scotland 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 Crieff?
Yes, Crieff is covered, along with postcode districts PH7. We also cover nearby Perth and Alloa.
Does the ground around Crieff cause cracking?
Perth and Kinross is largely Old Red Sandstone and Highland rock with glacial deposits and river alluvium along the Tay, which can be soft and flood-prone. Only an investigation can say why a particular building has moved.
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.
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.
