Surveys, design, and installation across Nottingham and surrounding towns.

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

Our Nottingham team handles foundation repair across the wider Nottinghamshire area. We regularly work in Mansfield, Newark-on-Trent, Worksop, Retford and Kirkby in Ashfield, 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 Nottingham

moderate prevalence

A patchwork of Mercia Mudstone, Lias clays, glacial till, and sandstone.

Variable ground; clay-rich pockets and former mining sites are the main concerns.

  • Sherwood Sandstone bedrock with cave network
  • Localised mine workings
  • Mercia Mudstone in outer areas

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 Nottingham properties.

Method Time on site Best for in Nottingham
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 Worksop and Retford 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 Retford and Kirkby in Ashfield, 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 Nottingham, Mansfield and Newark-on-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 Nottingham and Kirkby in Ashfield, 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 Nottinghamshire, suited to lighter loads in Mansfield and Worksop.
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 Newark-on-Trent and Mansfield, with quick installation and minimal spoil.
