Weak ground conditions beneath historic structures required strengthening to prevent settlement, while protecting sensitive heritage fabric and avoiding intrusive excavation works.
Solution
Geobear delivered precision geopolymer injection to strengthen underlying soils and fill voids, providing controlled ground improvement with minimal disturbance to the historic building.
Ground strengthened
Improved bearing capacity achieved
Heritage structure protected
Non‑intrusive methodology used
Minimal disruption
No large‑scale excavation required
Background
Historic buildings are particularly vulnerable to ground movement, and traditional stabilisation methods can pose risks to fragile masonry and original features.
Ground improvement solutions must therefore be carefully controlled and minimally invasive.
Challenge
Settlement risk beneath the structure required intervention to improve soil strength and long‑term stability.
Conventional underpinning or excavation would have introduced unnecessary disturbance to the heritage asset.
Solutions
Geobear implemented a targeted geopolymer injection programme through small, discreet access points.
The expanding resin filled voids and densified weak soils beneath the foundations, increasing bearing capacity and reducing future settlement risk.
Continuous monitoring ensured precise control throughout the process.
Results
The ground was successfully strengthened, safeguarding the historic structure against further movement.
The solution provided long‑term stability while preserving the integrity and character of this important heritage building.
