Our process

How does it work?

In 1980 Geobear invented a solution that uses geopolymer injection to act as an alternative to underpinning.

We will design a solution based on the ground conditions beneath your home and develop an engineered treatment plan for your property. This will be implemented by our site teams to improve the ground beneath your foundations. 

This result is the equivalent to underpinning, which strengthens the foundations. However, where concrete underpinning a house requires weeks of excavation, the Geobear solution can usually be completed within a day. 

With Geobear's resin underpinning solution you will receive a certificate of structural adequacy and insurance-backed guarantee.

1

The treatment plan

Engineered solution

Each treatment plan is designed to the specific conditions of your soil, foundation, and issues.

2

Drilling

Site prep and drilling

Our technicians will scan for utilities, mark the drilling points, and drill to the required treatment depth.

3

Injection

Geopolymer treatment

We insert tubes into the drilled holes, this allows us to precisely inject the geopolymer at the required levels according to the plan.

4

Precision control

Laser monitoring

During the injection process we monitor the foundation movement down to fractions of an inch using laser level monitoring.

5

Job done

Easy site cleanup

With no heavy machinery involved like underpinning, our crew will clean up their gear and equipment and leave your home looking undisturbed.

Specialist engineered solution.

Non-disruptive; uses small diameter holes.
Most insurance policies require action once a defect is known. Ignoring it may complicate future claims or selling. Factor in "hidden costs" like alternative accommodation, storage, and replanting and landscaping, or fixing floors afterwards. Ideal if your priority is minimising stress and protecting asset value without turning your home into a building site.

Frequently asked questions

Common signs include new diagonal cracks (often wider at the top), sticking doors or windows, and rippling wallpaper.

While these are strong indicators, the only way to know for certain is with a professional assessment. We can help with an initial, no-obligation video assessment to evaluate the signs.

Traditional underpinning requires major excavation, concrete, and weeks of disruption.

We inject material through small tubes drilled into the ground, with no need to dig up your yard or have you move out.

It’s faster, cleaner, and can be completed in as little as one day.

The cost varies depending on the scale of the problem and your property type. However, because our process avoids major excavation and is completed much faster than traditional methods, it is often a more cost-effective solution overall.
