Underpinning in Stoke-on-Trent

Surveys, design, and installation across Stoke-on-Trent and surrounding towns.

  • UK-wide coverage and local knowledge
  • 20 year remedial warranty
  • Diagnostics to remedial work

Our Stoke-on-Trent team handles foundation repair across the wider Staffordshire area. We regularly work in Stafford, Burton upon Trent, Lichfield, Tamworth and Cannock, on Victorian terraces, semi-detached houses, modern builds, and commercial properties.

Local coverage

Every job starts with a free site survey. A chartered structural engineer signs off the design before any work begins, and the installation is backed by a 10-year workmanship guarantee.

Ground conditions in Stoke-on-Trent

moderate prevalence

Mercia Mudstone underlies most of the region, with bands of Coal Measures and glacial till.

Mercia Mudstone shrinks less than London Clay but former mining can leave voids.

  • Mercia Mudstone bedrock
  • Historic coal-mining ground in places
  • Glacial till on higher ground

Methods we use locally

The right method depends on soil conditions, depth of failure, and access on site. The engineer's design decides, these are the options on the table for Stoke-on-Trent properties.

Method Time on site Best for in Stoke-on-Trent
Beam and base

Reinforced concrete beams that spread the load.

2 to 6 weeks Variable ground, bay windows, redistributing loads. Common on bay windows and settled extensions through Lichfield and Tamworth where loads need redistributing along a single elevation.
Foam injection

Lightweight stabilisation that works to depth.

1 day for most jobs Slab re-levelling, void fill, conservatory bases. Useful for re-levelling slabs and floors in Tamworth and Cannock, where access for excavation is tight and disruption must be kept low.
Mass concrete

The traditional method, done properly.

2 to 6 weeks per elevation Shallow failures on traditional ground, insurance claims. Well-suited to traditional brick properties across Stoke-on-Trent, Stafford and Burton upon Trent where shallow bays can reach competent ground by hand.
Mini piled

When the good ground is a long way down.

1 to 3 weeks on site Deep bearing layers, made-up ground, restricted access. The usual answer for deep clay or made-up ground around Stoke-on-Trent and Cannock, and for rear-only access through the property.
Resin injection

Targeted ground improvement, no excavation.

1 day for most jobs Granular soils, intact foundations, voids and density loss. Quick non-disruptive fix for shallow void filling and ground stabilisation across Staffordshire, suited to lighter loads in Stafford and Lichfield.
Screw pile

Helical piles, no concrete cure time.

2 to 5 days Lighter loads, time-critical jobs, conservatories. Low-vibration option for terraces close to neighbours in Burton upon Trent and Stafford, with quick installation and minimal spoil.
