What is Geopolymer Injection?
Geopolymer injection is an advanced ground improvement method used to stabilise soil, fill underground voids and restore structural integrity without excavation.
The process involves injecting expanding resin into the ground through small holes. As the material expands, it compacts the surrounding soil, increases load-bearing capacity and can precisely lift structures.
This technology is widely used in construction and infrastructure projects where fast and minimally invasive solutions are required.

Soil stabilisation is required when ground conditions compromise structural stability, load-bearing capacity or long-term performance of infrastructure and foundations.

How Geopolymer Injection Works
Site inspection
Assessment of soil conditions and structural issues.
Drilling Injection Points
Small diameter holes are drilled in targeted locations.
Resin Injection

Frequently Asked Questions
Geopolymer resin injection is an advanced ground engineering method used for soil stabilisation, foundation repair, and subsidence treatment. The expanding resin is injected into weak or loose soils to improve bearing capacity, stabilise foundations, and in some cases lift settled structures.
Compared with traditional underpinning methods such as concrete underpinning, geopolymer injection can provide a faster and less disruptive solution because extensive excavation is typically not required. Depending on ground conditions, structural loads and project requirements, the work can often be completed with minimal downtime while the facility remains operational.
During geopolymer resin injection, the material is injected through small-diameter holes into targeted zones beneath or around the structure. As the resin expands, it fills voids and compacts the surrounding soil. Injection parameters and structural movement are monitored to achieve controlled ground improvement and, where required, precise lifting.
Yes. Geopolymer injection can be used for commercial and industrial facilities, warehouses, logistics hubs and infrastructure where excavation and prolonged downtime are undesirable. The solution is designed according to site conditions, structural loads and the required engineering outcome.
Geopolymer injection can be used for subsidence treatment where settlement is associated with weak or loose soils, voids, or insufficient ground bearing capacity. The suitability of the method depends on the cause of settlement, soil conditions and structural requirements, which should be assessed before the injection solution is designed.
