About GSI
GeoStabilization International is a global ground-engineering group delivering stabilisation solutions for critical infrastructure, transport networks, slopes, and high-risk assets.
Backed by more than 20 years’ experience working within the residential house design and build market, the same engineering discipline, technology, and quality systems are now applied to homes through GSI Residential.
What we do
GSI Residential provides engineered solutions for ground movement, subsidence, foundation instability, and re-levelling. Every project begins with investigation and design. We then apply the most appropriate method (or combination of methods) to address the cause of movement, not just the visible symptoms.
How we do it
Our approach is design-led and precision-controlled. We use advanced ground-engineering technologies, including polyurethane injection and engineered piling, as tools within a tailored solution. Installation is measured, monitored, and verified, ensuring accuracy, minimal disruption, and long-term performance.
Why it matters for your home
Homes are some of our biggest assets. Ground behaviour is complex and site-specific. By applying infrastructure-grade engineering to residential properties, GSI Residential delivers clear diagnosis, precise execution, and accountable outcomes—bringing confidence, stability, and protection to your home.
