Ground improvement – York Hospital

Challenge

Weak and variable ground conditions at York Hospital required stabilisation to protect structural performance, without disrupting critical healthcare operations.

Solution

Geobear delivered precision geopolymer injection to strengthen soils and increase bearing capacity, enabling ground improvement works with minimal operational impact.

Live healthcare environment

Works delivered within operational hospital site

Targeted in situ strengthening

No bulk excavation required

Rapid curing material

Minimal programme and access impact

Background

Ground investigations at York Hospital identified areas of reduced bearing capacity beneath proposed or existing structures.

Given the critical nature of healthcare facilities, maintaining operational continuity throughout remediation was essential.

A solution was required that would deliver measurable soil improvement while minimising noise, vibration and disruption.

Challenge

Traditional excavation or piling works would have introduced significant disturbance, extended programme duration and potential impact on sensitive hospital operations.

The client required a controlled, low‑impact alternative capable of strengthening the ground efficiently within a constrained environment.

Solutions

Geobear implemented a designed geopolymer injection programme to improve the mechanical properties of the underlying soils.

Small‑diameter injection points were installed at calculated depths to introduce a two‑component geopolymer beneath the affected areas. Upon mixing, the material expanded to fill voids, bind loose soils and increase stiffness.

Injection was monitored in real time to ensure controlled improvement and protection of adjacent structures and services.

Results

Ground bearing capacity was enhanced and settlement risk mitigated without intrusive construction methods.

The works were delivered efficiently within a live hospital setting, providing a durable and lower‑carbon alternative to traditional ground improvement techniques.
