Stabilisation of canal bank

Challenge

Canal bank instability and erosion threatened structural integrity and surrounding infrastructure, requiring remediation without draining the canal or disrupting operations.

Solution

Geobear delivered targeted geopolymer injection to stabilise soils, fill voids and control seepage, strengthening the canal bank with minimal disruption.

Bank stabilised

Ground strength improved

Void filling achieved

Erosion pathways sealed

No major excavation

Minimal environmental impact

Background

Canal banks are vulnerable to erosion, seepage and internal void formation over time.

If left untreated, progressive instability can result in embankment movement, leakage and risk to adjacent assets and infrastructure.

Traditional repair methods often involve significant excavation or temporary closure.

Challenge

The canal bank showed signs of instability and internal erosion, raising concerns about long‑term performance.

A solution was required that could be installed from the surface, without draining the waterway or causing operational disruption.

Solutions

Geobear designed and implemented a controlled geopolymer injection programme to target weak zones within the embankment.

The expanding resin filled voids, improved soil cohesion and increased shear strength.
Works were completed with minimal plant and no need for extensive excavation.

Results

The canal bank was successfully stabilised, reducing erosion risk and restoring long‑term structural integrity.

The solution minimised environmental disturbance and avoided operational downtime.
