Stabilisation of a road in Reading

Challenge

Road settlement created uneven carriageway levels, affecting ride quality and requiring stabilisation works with minimal traffic disruption on a live route.

Solution

Geobear delivered targeted geopolymer injection beneath the carriageway to stabilise weak subgrade and re‑level affected areas quickly, avoiding excavation and extended road closures.

Carriageway stabilised

Targeted ground improvement beneath live road

Minimal traffic disruption

Works completed under controlled access

No excavation required

Non‑intrusive treatment method

Background

Ground movement and loss of support beneath road structures can lead to surface deformation, cracking and reduced ride quality.


Traditional repairs often require excavation and reconstruction, leading to traffic delays and higher costs.

Challenge

The project required a rapid, non‑disruptive stabilisation solution that could be delivered safely on a live road network while restoring structural support and surface performance.

Solutions

Geobear implemented a precision geopolymer injection programme through small drilled access points in the carriageway.

The expanding geopolymer resin filled voids and strengthened the underlying soils, improving bearing capacity and stabilising the affected section.

Real‑time monitoring ensured controlled injection and accurate treatment of target areas.

Results

The carriageway was stabilised efficiently without full reconstruction, significantly reducing disruption and programme time.

The solution extended the service life of the road while minimising cost and environmental impact.
