Repair methods used across Hampshire

Each method suits different ground conditions. The right choice depends on what lies beneath your foundations and how far movement has progressed.

  • a house with a tower in the background

    Underpinning

    The specialist excavates below existing footings and pours concrete in controlled stages to deepen support where shallow soils have failed.

  • Three construction vehicles parked in a field

    Resin injection

    The specialist pumps expanding resin into voids beneath the slab, compacting loose material and lifting settled sections back toward level.

  • A village destroyed by an earthquake, showcasing damaged buildings and debris.

    Concrete cracking

    The specialist examines cracked slabs and drives, determines whether settlement caused the damage, and stabilises the ground before repair.

    Screw piling

    The specialist drives steel piles through soft fill or brickearth down to a load-bearing stratum, bypassing weak upper layers entirely.

Local geology

Why Havant ground moves

Brickearth foundation problems Havant residents face stem from the same local geology that defines the town.

  • Spring lines and ground water Springs rising from the chalk interface saturate superficial clay layers. If there is a spring line near your road, ground water under house cracks is a likely cause rather than simple drying.
  • What brickearth is Brickearth is a wind-blown silty clay deposited over gravel. It shrinks when dry and softens when wet, so shallow foundations built directly on it move with every season.
  • Cracked and tilted floor slabs A cracked floor slab repair Havant homeowners request often follows differential settlement. The specialist distinguishes between a slab settling on its own and the whole footing dropping.
  • Blocked drains washing soil away A leaking or blocked drain can wash fine particles from beneath footings. A drain survey subsidence Havant specialists recommend will show whether water is eroding the supporting ground.
  • Is it just my house? Movement along a spring line ground movement path rarely stops at one boundary. A havant soil investigation house by house reveals whether neighbours share the same risk.

Subsidence services available in Havant

Havant sits on brickearth and gravel above chalk, with springs creating shifting moisture. These five approaches address that specific mix.

  • Subsidence help in Havant

    The specialist visits the home, maps crack widths and directions, and checks for drainage faults. Because springs rising from the chalk interface affect moisture levels locally, they record how close the property sits to known water paths before recommending next steps.

  • Underpinning in Havant

    Where brickearth has softened or washed away, the specialist digs beneath the existing footings in short bays and fills them with concrete. This transfers the load past the unstable surface layer to deeper gravel or chalk, halting further downward movement.

  • Resin injection in Havant

    The specialist drills small holes through the slab or alongside strip footings and injects structural resin. In soft brickearth the resin compacts loose silt and fills voids left by escaping water, providing support without the excavation that traditional methods require.

  • Concrete cracking in Havant

    Post-war housing in Havant often has unreinforced floor slabs poured directly onto brickearth. The specialist determines whether the cracking stems from ground loss or simple thermal movement, then stabilises the subsoil before repairing or replacing the damaged concrete.

  • Screw piling in Havant

    When brickearth is too soft for resin or too deep for conventional underpinning, the specialist drives helical steel piles through it to the underlying gravel or chalk. This bypasses the problematic layer entirely and gives the home a fixed bearing point.
