City street with Utilities

Overview

The ground surrounding utilities infrastructure is constantly at risk from water ingress, soil erosion, and changing ground conditions. This can lead to voiding around pipes, manholes, and cable trenches, causing settlement and structural instability.

The traditional method to this repair involves excavating roads and land, leading to significant disruption to services and the public.Geobear offers a different approach. We design a solution that involves the injection of a self-expanding, specially engineered resin directly into the ground through small, 12-16mm holes. This process fills voids, compacts the surrounding soil, and helps to re-level structures. Our methods are up to 70% faster and have a 75% lower carbon impact than traditional alternatives, allowing you to maintain operations while we work

Challenges Geobear can solve

Sewer ground strengthening

Remediate structural movement affecting water, gas, and sewer pipes.

Water sealing

We provide a rapid solution to reduce permeability and help seal against water ingress, which can lead to further erosion and voiding.

Void filling around pipes and conduits

We fill washouts and voids in the subgrade, restoring the integrity of the ground supporting buried pipes and cables.

Sub-station ground improvement

We improve the ground to provide a stable foundation, protecting assets from movement and damage.

Manhole stabilisation and re-levelling

We strengthen the ground beneath and surrounding manholes, and can lift them back to their correct level, preventing further settlement.
