Is Bedfordshire prone to ground movement?

Postcode districts SG18 cover Biggleswade, a Bedfordshire town of about 17,000 people. We also take enquiries from nearby Letchworth Garden City (8 miles), St Neots (9 miles) and Bedford (9 miles).

Shrinkable clay is widespread in Bedfordshire. Ground movement here is more often linked to soils, drains and trees than to mining. What you mostly find across Bedfordshire: Victorian terraces in Bedford and Luton, large inter-war and post-war estates, and newer estates on former clay pits and brickfields.

Methods for bowing wall repairs

Stitching a delaminating wall

Where the layers of a solid wall have separated, long stainless ties are drilled in from the face and bonded into the inner layer to bind the wall together again. This is often combined with restraint ties, so the wall is both reconnected through its thickness and tied back to the structure.

Best for: Solid walls where the outer layer has pulled away

Restraint ties into the floor

Stainless restraint ties are drilled through the wall and fixed into the floor joists or into blocking between them. Where joists run parallel, noggins are fitted across several joists so the tie has something solid to hold. A neat plate or a buried fixing is left on the outside face.

Best for: Walls bowing at floor level where joists run alongside

From first photo to finished repair

Assess the bow
We look at where the wall bows, how far it is out of plumb and how the floors and roof meet it. Photographs from your phone held flat against the wall often show the shape clearly before anyone visits.
Decide restrain or rebuild
If the wall is badly out of plumb, has bricks crushing or follows removed internal walls, we recommend an engineer, and can arrange one. Their view sets whether restraint is enough or a section needs rebuilding.
Open up inside
Floorboards or a ceiling strip are lifted along the affected wall to expose the joists. We fit noggins where joists run alongside, and plan furniture moves with you, since this is the most disruptive part of the job.

Rules for bowing wall repairs 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 bowing wall repairs cost in Biggleswade?

Is the ground in Bedfordshire prone to subsidence?

Much of Bedfordshire sits on Oxford Clay and Gault Clay, with chalk rising towards the Chilterns in the south. The clay vales shrink in dry summers and swell in wet winters, which is why seasonal cracking is common around Bedford. Only an investigation can say why a particular building has moved.

Is a bowing wall dangerous?

A bowing wall is not always dangerous, but it should never be ignored. Many have been slightly out of line for decades. A bow that is growing, crushing bricks or appeared after building work is more serious, and an engineer should look at it promptly. Your engineer will confirm.

What is lateral restraint?

Lateral restraint is the connection that stops a wall moving sideways, provided by tying it to the floors and roof. Older houses often have little or none, especially where joists run parallel to the wall. Remedial ties and straps add that connection after the event.
