Underpinning Sydney

Sydney homeowner trying to stop your home from sinking?
You’re in the right place

Traditional underpinning can stabilise your Sydney home if it’s suffering from subsidence. This old-fashioned method works and is still being used today. However, traditional underpinning causes massive disruptions to —

Your home's structure

For traditional underpinning methods to work, builders and engineers need to hollow out all of the soil from beneath your Sydney home. This physically messy operation can put the structural integrity of your home at risk.

Your life

Because builders and engineers are digging out the ground from underneath your home, you’re forced to move elsewhere for weeks and deal with the inconvenience. If something happens to go wrong, you could be out of your home for months.

Your wallet

Traditional underpinning can get extremely expensive. It requires a ton of manpower and time. As a result, traditional underpinning can cost between $20,000 to $100,000 for all the effort. It may cost even more time and money if your home is on the larger side.

Last but not least, there are no guarantees with traditional underpinning. 

After all the physical work, inconvenience and money spent, the likelihood of your home staying level and stable is still relatively low.

A modern method of underpinning for Sydney homeowners

At Buildfix, we offer Sydney homeowners a completely modern method of underpinning. Our method is the direct opposite of the traditional one in every way.

The process of underpinning Sydney home from top level

We investigate your Sydney home

Our underpinning process always starts with an investigation phase. With our extensive engineering experience and technical skills we get to know your home from top to bottom and inside and out. 

The aim of investigating is to measure the levels of your home as well as to pinpoint specific problems under your home’s foundations. By doing this, we apply strategic solutions with efficiency and accuracy.

We inject GeoPoly™ in all the right places

Once we’ve come to know your home well, we bring in GeoPoly™, our proprietary geopolymer resin. When injected at strategic points under your home, GeoPoly™ finds all voids, gaps and weaknesses in the ground. 

Being completely safe and controllable, GeoPoly™ negates the need to dig monstrous holes under your Sydney home. And the need to disrupt your life and your wallet.

Lifting your home

Once injection of GeoPoly™ is completed, weak and/or aerated ground under your home will become solid within minutes
