Is Hampshire prone to ground movement?

Waterlooville (PO7, PO8, PO9) has around 64,000 residents and sits in Hampshire. Nearby, we also cover Havant (3 miles), Emsworth (5 miles) and Portsmouth (6 miles).

Much of Hampshire sits on clay that shrinks in dry summers and swells in wet winters. Ground movement here is more often linked to soils, drains and trees than to mining. Across Hampshire, most homes are Victorian terraces in Portsmouth and Southampton, 1930s semis, and large post-war and new-build estates.

How we usually approach retaining wall repairs

Drainage and minor repairs

Blocked weep holes are cleared or new ones drilled, and where practical a drainage layer is formed behind the wall with an outlet at its base. Loose copings are rebedded, open joints repointed and a few damaged bricks replaced. For a low wall that has not moved much, this can be enough.

Best for: Low walls that are damp or slightly weathered but still upright

Temporary support and reducing load

While a repair is designed and programmed, a dangerous wall may be propped, or soil and loads near the top removed to reduce the push. Moving parked cars or a shed back from the wall is sometimes the simplest first step.

Best for: Walls that are moving now and need making safe

What happens during retaining wall repairs, step by step?

Engineer’s design
Where the wall needs it, an independent chartered structural engineer is appointed to design the repair or new wall, including footing, thickness, reinforcement and drainage. We can arrange this, and the design forms the basis of the quote.
Written quote
You receive a no-obligation written quote covering demolition, excavation, temporary support, the footing, the new or repaired wall, drainage and spoil removal. It becomes a fixed price in writing once the repair is specified.
Build and drain
The failing section is taken down, the soil supported in short lengths, and the footing cast. The wall is rebuilt with drainage behind it, backfilled with free-draining material, and building control inspects where the work needs it.

Rules for retaining 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.

Why do houses in Hampshire crack?

Central Hampshire is chalk, while the south around Portsmouth, Southampton and the New Forest fringe and the north-east around Farnborough sit on London Clay, Reading Beds and other clays and sands. The clay areas see seasonal movement near trees. Only an investigation can say why a particular building has moved.

Is a leaning retaining wall dangerous?

It can be, especially if the lean is getting worse, the wall is tall, or there is a path, drive or building next to it. A wall that has leaned slightly for decades may be stable, but one that has moved recently should be kept clear and assessed soon.

Does home insurance cover a collapsed garden retaining wall?

Often not, because many policies exclude garden walls unless the house is damaged by the same event, and gradual failure is usually excluded. A collapse caused by landslip or a sudden escape of water may be treated differently. Check your schedule and tell your insurer before permanent repairs start.
