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?

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.
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 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 Hull

How much should I budget for underpinning in Hull?

Guide prices for underpinning in Hull 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.

Can you survey a property in Hull?

We do. Hull and the surrounding area are covered, including nearby Beverley and Goole. A free initial assessment from your photos is the first step.

Why do houses in East Riding of Yorkshire crack?

The Yorkshire Wolds are chalk, while Holderness and Hull sit on glacial till and estuarine clays and silts. Soft alluvial ground near the Humber can settle, and the Holderness coast is one of the fastest-eroding in Europe. Only an investigation can say why a particular building has moved.

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.

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.
