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.
Problems Solved by Geopolymer Injection
-
Foundation settlement and structural cracks -
Voids beneath slabs and foundations -
Weak or loose soil conditions
-
Uneven floors, pavements and industrial slabs -
Soil instability around structures
Applications
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
Expanding geopolymer resin is injected into the ground.
Soil Compaction and Lifting
The material expands, compacting soil and lifting structures where required.
Control and Monitoring
Process is monitored to ensure precision and stability.
Advantages of Geopolymer 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.
During the geopolymer resin injection process, the material expands within the soil to fill voids, compact weak ground, and strengthen the foundation zone. This technique provides fast and precise ground improvement without excavation.
When compared with traditional underpinning methods such as concrete underpinning, geopolymer injections are faster, less disruptive, and often more cost-effective. They can usually be completed within hours rather than days or weeks.
Yes, geopolymer injections are widely used for commercial property, industrial facilities, warehouses, and infrastructure projects where downtime must be minimised and immediate structural support is required.
Yes, geopolymer injections are highly effective for subsidence treatment because they stabilise weak soils, restore load-bearing capacity, and help prevent further settlement.
