Underpinning in Hull

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

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

Our Hull team handles foundation repair across the wider East Riding area. We regularly work in Beverley, Bridlington, Driffield, Goole and Cottingham, 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 Hull

moderate prevalence

Coal Measures, Magnesian Limestone, and glacial till dominate, with alluvium along major rivers.

Mining legacy and made-up ground are bigger factors here than clay shrinkage.

  • Soft estuarine alluvium across much of the city
  • High water table
  • Made-up ground in former dock 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 Hull properties.

Method Time on site Best for in Hull
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 Driffield and Goole 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 Goole and Cottingham, 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 Hull, Beverley and Bridlington 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 Hull and Cottingham, 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 East Riding, suited to lighter loads in Beverley and Driffield.
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 Bridlington and Beverley, with quick installation and minimal spoil.
