Newham Hill bridge approach – ground improvement

Challenge

Settlement and loss of support beneath the bridge approach created uneven levels and structural concerns, requiring stabilisation without major excavation or prolonged traffic disruption.

Solution

Geobear used precision geopolymer injection to strengthen weak sub‑soils, fill voids and re‑stabilise the bridge approach quickly with minimal disruption.

Bridge approach stabilised

Targeted ground improvement

Minimal traffic disruption

Rapid installation process

Non‑intrusive method

No large‑scale excavation required

Background

The approach to Newham Hill Bridge experienced settlement due to weakened or poorly compacted sub‑soils. Movement resulted in uneven surfaces and raised concerns regarding long‑term performance and safety.

A fast, low‑impact remediation method was required to avoid extended closures and costly reconstruction.

Challenge

Traditional excavation and reconstruction would have involved traffic management, extended programme durations and significant cost.

The client required a solution that restored load‑bearing capacity and stability while maintaining operational continuity.

Solutions

Geobear delivered a controlled geopolymer injection programme beneath the affected bridge approach.

Through small injection points, expanding geopolymer was introduced into weak and voided zones. The material compacted loose soils, increased bearing capacity and restored support to the structure.

Works were monitored in real time to ensure accurate delivery and controlled ground response.

Results

The bridge approach was successfully stabilised without excavation or prolonged closures.

The solution provided improved ground performance, extended service life and reduced environmental impact compared with traditional reconstruction.
