How we usually approach underpinning

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 happens during underpinning, step by step?

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.

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.

Questions about underpinning in Halifax

How much will underpinning cost in Halifax?

Guide prices for underpinning in Halifax 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 Halifax?

Yes, Halifax is covered, along with postcode districts HD6, HX1, HX2, HX3. We also cover nearby Elland and Brighouse.

Is the ground in West Yorkshire prone to subsidence?

West Yorkshire lies largely on the Coal Measures, with shallow historic workings around Leeds, Wakefield and Kirklees, and gritstone hills to the west. Steep sites mean retaining walls are common. 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 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.
