Cracks above the windows in my Eastleigh terrace

Railway-era terraces here sit on shallow foundations over river terrace gravels and London Clay. When that clay dries or compresses, the walls move. Cracks appear where the brickwork is weakest, often around window openings.

    Diagonal cracks near windows

    A crack running at an angle from a window corner can mean the wall is dropping on one side. It might also be seasonal drying.

    Doors catching on frames

    A door that sticks in summer but swings free in winter suggests the frame has shifted slightly with the ground below.

    Gaps at skirting boards

    A visible gap between the floor and the skirting board can indicate the floor slab has dropped away from the wall.

    Cracks wider than 2mm

    Hairline cracks are common in old brickwork. A gap you can fit a coin into usually means something has moved recently.

Eastleigh ground conditions

Why houses near the railway works move

The town grew fast around the carriage works, so builders used whatever ground was available, including filled land and variable gravel beds.

  • River terrace gravels over clay Many streets rest on gravel sitting directly on London Clay. The clay shrinks in dry summers, pulling support away from shallow footings.
  • Made ground and old fill Pockets of housing were built on old railway fill. This made ground compacts unevenly over decades, causing floors to dip and walls to split.
  • Train vibration versus ground loss Vibration from passing trains shakes loose mortar, but it rarely causes structural cracks on its own. Persistent widening points to the soil moving.
  • Shallow foundations in terraces Victorian and Edwardian builders dug trenches barely two feet deep. Shallow foundations leave terrace movement far more likely when the subsoil changes moisture.

  • Underpinning in Eastleigh

    Where shallow foundations terrace movement has left a wall unsupported, a contractor excavates beneath the existing footing in short bays and pours new concrete to reach stable strata. Underpinning in Eastleigh suits detached or end-of-terrace homes where access allows digging alongside the party wall safely.

  • Resin injection in Eastleigh

    A technician pumps expanding geopolymer resin through small holes drilled in the floor slab or beneath strip footings. Resin injection in Eastleigh fills voids in compacted fill and lifts settled concrete without heavy excavation, which suits narrow terraced plots where machinery cannot easily reach.

  • Concrete cracking in Eastleigh

    Slab floors in garages and extensions often split when the ground beneath them settles. A specialist addresses concrete cracking in Eastleigh by stabilising the sub-base first, then either stitching the slab or replacing sections where the damage has gone beyond simple repair.

  • Screw piling in Eastleigh

    On streets built over old railway fill, driven steel piles bypass the loose material entirely to bear on deeper gravel or clay. Screw piling for a terraced property in Eastleigh uses compact rigs that fit down narrow side passages, avoiding the need for large concrete pours.
