Is your Brisbane home

unstable and sinking into the ground?

You may have spoken to engineers and considered their traditional underpinning methods already.

However, traditional methods have drawbacks —


With traditional underpinning techniques, builders and engineers dig out the ground from under your home. After they hollow the soil out, they pour concrete into the gap to stabilise everything. This is a laboured, lengthy process that increases the possibility of further structural problems developing.


While your home’s structural integrity is at risk, you and your family are at risk. This means you can’t be on the premises while they’re at work. Traditional underpinning forces you to find temporary residence elsewhere for at least a few weeks. And if complications occur, you’ll be out of your home for months.


Traditional underpinning can cost between $20,000 to $100,000 because so much manpower, time and effort is required. It can cost even more if your home is larger than the average one. If problems occur and you’re paying for temporary residence, this will eat into your wallet even further.


A lot of builders and engineers offer a warranty on traditional underpinning of no more than 2 years. The reason is more often than not, the traditional method of underpinning fails. The short warranty period is to create an opportunity to dig deeper into your wallet and maximise profits.

underpinning brisbane homes:
a summary of the process

We investigate your Brisbane home

Our underpinning method begins with an investigation. We take the time to learn the ins and outs of your home’s structure. We make note of your home’s levels and we see if there are any specific challenges under your home’s foundations.

The investigation process arms us with a true understanding of your home. This understanding, combined with our extensive engineering experience and technical skills, allows us to apply our underpinning solutions strategically, efficiently and accurately.

We inject GeoPoly™ in strategically chosen spots

Having thoroughly investigated your home, we begin injecting GeoPoly™ in specifically chosen spots under your home.

GeoPoly™ is our proprietary geopolymer resin solution. It seeks out gaps, voids and/or weaknesses in the soil beneath your home. Our expert application of GeoPoly™ is the reason holes don’t need to be dug and you get to save so much money.

Lifting your home

GeoPoly™ solidifies the ground only minutes after injection through chemical expansion pressure. Aerated and weak soils solidify and if the conditions are correct, large gaps may close up.

The ground on which your home was built can now bear a far greater weight. Your home will stand steady and level for decades.
