Helping to protect your biggest asset
Mainmark has raised, re-levelled and re-supported homes and buildings for over 20 years, delivering successful solutions to thousands of residential homes and hundreds of non-residential projects internationally, including Australia, New Zealand, Japan and Thailand.
Sinking floors, paths and driveways, cracked walls, jamming doors and windows can all be indicators of structural damage. Causes are various and include; building subsidence, bearing on unstable or weak ground, a broken pipe causing erosion, moisture changes in clay soil, and earthquake liquefaction. Our solutions are cutting edge and the modern answer to the traditional way to underpin; it is like keyhole surgery compared to concrete underpinning. Our alternatives to underpinning are not just for concrete slab floors. We can underpin, raise and re-level strip footings and raft slabs, plus we can infill slabs and driveways. We are experienced in a number of ground engineering techniques – including, in the past Uretek, now our proprietary Teretek engineered resin solution and JOG Computer Controlled Grouting – all non-invasive methods that are cost and time efficient.

Residential Resin Injection
Mainmark can use a variety of tested and proven specialised engineered resins to bind weak strata and fill voids, crevices, and large cavities in civil and mining applications.

Cracks in Walls Closed Up
Mainmark’s level correction methods are effective for cracks in walls in buildings of any size, including residential homes. We visit your home, assess damage, and discover the cause. Our experienced engineers and technicians establish the underpinning approach needed, creating a plan specific to the needs of your house.

JOG Computer-Controlled Grouting
JOG Computer-Controlled Grouting is an award-winning grouting technology for re-levelling and strengthening ground beneath large structures using computer-controlled cement grout injection. It is an extremely precise method for stabilising soils, consolidating weak ground and lifting foundations to deliver specific, engineered outcomes, regardless of complexity.
Learn moreUnlike many level correction processes, our methods are very resident-friendly.
We use non-invasive techniques, likened to keyhole-surgery, so we don’t tear up floors and excavate ground (the injection holes can be as small as 6mm). |
|
We are very quick – on many jobs we are done in a day. |
|
More often than not residents can stay in the home and may not even need to move much furniture. |
|
We strengthen the future of the house – the methods we use strengthen weak ground, so your home generally becomes level, crack-free and more stable. |
|
We don’t make mess – there’s no concrete dust, water or anything else to clean up. |
|
We don’t cause further damage; in fact cracks generally close up and windows and doors become usable. |
