Care home ground improvement

Challenge

Weak and variable ground conditions threatened foundation performance on a live care home development, requiring stabilisation without delaying programme or introducing disruptive excavation.

Solution

Geobear delivered engineered geopolymer injection to improve bearing capacity and control settlement, enabling foundation works to proceed with minimal programme impact.

Background

Ground investigations at a UK care home development identified areas of weak and variable soils that posed a risk to foundation performance. Differential settlement could have affected structural integrity and long‑term serviceability if not addressed.

With the project operating to a defined construction programme, a stabilisation method was required that could be delivered efficiently without extensive excavation or redesign of the foundation system.

Challenge

Traditional ground replacement or piling solutions would have increased cost, programme duration and site disruption. Excavation of unsuitable material would also have introduced additional environmental and logistical considerations.

A ground improvement approach was needed that could enhance bearing capacity, reduce settlement risk and integrate within the active construction sequence without affecting neighbouring works.

Solutions

Geobear designed a targeted geopolymer injection programme based on site investigation findings and load requirements. Small‑diameter injection points were installed at predetermined locations within foundation and slab zones.

The two‑component geopolymer was injected at depth, where it expanded to bind loose soils, fill voids and increase stiffness. Injection parameters were controlled to achieve the required ground improvement without inducing detrimental movement.

The compact equipment footprint and rapid curing characteristics enabled works to proceed efficiently alongside other construction activities.

Results

Ground bearing capacity was improved and settlement risk mitigated without the need for large‑scale excavation or foundation redesign.

The intervention supported continued construction progress while delivering a technically robust stabilisation outcome aligned with long‑term asset performance requirements.
