Foundation and subsidence services

Each problem needs its own approach. A specialist firm carries out the investigation and repair, working from the survey findings to choose the right method for the ground beneath your home.

  • Worker in hi-vis using injection equipment on a cracked, stained house wall by bins and cars.

    Subsidence Survey

    The specialist inspects the building, measures movement and identifies the cause so the correct repair method can be chosen for your home.

  • Worker beside a red brick terrace house with an exposed foundation trench.

    Resin Injection

    A specialist injects structural resin into the ground to stabilise loose soil and lift settled foundations without large excavations.

  • Workers applying resin injection to a low brick garden wall beside a parked car.

    Mass Concrete Underpinning

    The specialist excavates sections below the existing footing and pours concrete to transfer the load of the wall to firmer ground.

  • Workers underpin a semi-detached brick house using steel beams along its base.

    Mini Piled Underpinning

    Where shallow ground is weak, the specialist drives piles deep into stable strata and builds a reinforced beam to carry the house.

  • Close-up of workers underpinning a brick house wall with new blockwork visible.

    Structural Monitoring

    The specialist fits gauges to track crack width and wall level over months, proving whether movement has stopped or is still active.

  • Workers in high-vis excavate around a pebble-dashed house corner for underpinning.

    Crack Repair

    Once the cause is fixed, the specialist stitches masonry cracks with helical bars and resin to restore the strength of the wall.

Questions about underpinning in Chilworth

Owners of larger detached houses near mature oaks often ask these questions before arranging a survey.

Could oak roots cause our cracking?
Mature deciduous trees on sandy Bagshot Beds extract moisture rapidly in summer. The specialist checks root proximity and soil shrinkage to confirm if oak tree cracking walls is the cause at your Chilworth home.
Will removing a tree make it worse?
Felling a mature oak can trigger heave as the dry soil reabsorbs water and swells. The specialist advises on phased crown reduction instead, managing moisture recovery safely.
Roots or a broken drain?
Both cause similar cracks. The specialist runs CCTV drain surveys alongside trial holes to distinguish root-related movement from a leaking pipe washing out the sand beneath the footing.
Underpinning a large detached house?
The specialist sequences excavation in short bays around the perimeter, pouring concrete or driving piles while the rest of the structure remains supported. Each bay cures before the next opens.
Part of the house or the whole wall?
Only the moving section needs support. The specialist pins the affected corner or elevation, tying the new depth back into the sound existing foundation.
How long until we know the repair?
Monitoring usually takes several months to capture seasonal movement. The specialist reviews the data before recommending a specific method, so early visits focus on gathering evidence.
