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

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

From first photo to finished repair

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.
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

Rules for underpinning in England

In England, underpinning and other work that alters or strengthens a wall or foundation is building work under the Building Regulations (Part A, structure), so building control approves and inspects it. Like-for-like repairs often are not, and we tell you which applies before a price is agreed. Work to a party wall, or excavation close to a neighbour’s foundations, can also need a notice under the Party Wall etc. Act 1996.

Frequently asked questions

How much will underpinning cost in Thornaby-on-Tees?

Guide prices for underpinning in Thornaby-on-Tees start from about £950 per metre of wall, including VAT, on Yorkshire and the Humber rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.

Do you cover Thornaby-on-Tees?

Yes. We take enquiries from across Thornaby-on-Tees, including TS16, TS17, TS18, and from nearby places such as Stockton-on-Tees and Yarm. Send photos for a free initial view and we will tell you what happens next.

Is the ground in North Yorkshire prone to subsidence?

North Yorkshire ranges from limestone dales and moors to clays and glacial deposits in the Vale of York, with the Selby coalfield in the south and ironstone workings in Cleveland. Teesside has areas of soft and made ground. 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.

Does underpinning need building control approval?

Yes, underpinning is building work and needs approval and inspections in England and Wales, a building warrant in Scotland, and council building control in Northern Ireland. Inspectors usually check the excavations before concrete is poured. We deal with building control as part of the job.
