What is GeoPoly™

GeoPoly™ is our proprietary geo-polymer injection technology. We have designed it specifically to seek out voids and weakness below walls and structures, for the purpose of stopping subsidence and reversing its effects. It’s unique properties can raise structures and may even close gaps in walls and re-level concrete slabs and floors. GeoPoly™ is a special form of polyurethane, a plastic. Polyurethane is one of the most widely used materials we use in society and can be found in many house hold items – it’s environmentally friendly.

When we’re on site, we combine number of chemicals to create GeoPoly™ to give it’s unique abilities. We inject GeoPoly™ into the ground underneath your home through small holes, which cause minimal disruption. Once it’s in the soil, it follows the path of least restraint expanding as it goes – generating huge forces. The force generated is more than enough to completely fill any voids and counter the compressinal force from the structure above. This will keep your home sitting up nice and straight for years to come.

GeoPoly™ underpins your home’s foundations

GeoPoly™ fills voids and compacts the soil under your home to counter the effects of subsidence fast. If your home is unstable due to eroded soil, moving clays, vibrations in the earth or even poor workmanship, our geo-polymer solution can stop movement in an instant. GeoPoly™ can make your home safer to live in for you and your family. And over time, it can help you save a small fortune. It’s the perfect alternative to expensive traditional underpinning.

GeoPoly™ is safe and doesn’t biodegrade

GeoPoly™ is made primarily from polyurethane, a solid and flexible plastic that can be found in thousands of products — even the clothes you’re wearing right now. GeoPoly™ is environmentally neutral and won’t biodegrade. You can be sure your home’s stable while your family is safe from harm.

GeoPoly™sets within minutes

In minutes, GeoPoly™ can lift your floors, your walls and even large concrete slabs. GeoPoly™ cures quickly, transforming from a liquid into a solid almost instantly to fill voids, consolidate aerated soil and protect your home from sinking quickly.

GeoPoly™ can lift your home

If your home’s been sinking due to unstable foundations, GeoPoly™ can give it a lift. After we inject GeoPoly™ into the ground, it uniquely sets and forms a powerful honeycomb structure at the molecular level. This structure can expand up to 30 times its original volume depending on temperature and moisture variations in the soil under your home. The lift is fully control with precision measuring equipment. As GeoPoly™ expands, it can rejoin walls with roof structures, close wall crack gaps and much, much more.
