Raise, re-level and re-support your home with Mainmark’s cost effective, non-invasive solutions

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, raft slabs and ‘Waffle-Pod’ 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.

When I found we had to re-level our house I did alot of research.
Mainmark allowed us to stay in the house, which was great.
Our gardens weren’t dug up and the driveway was left alone.
Mainmark really made a difference.

Bob Foster Tai Tapu, Christchurch

We are so pleased with Mainmark’s efforts in levelling our garage.
There was little disruption and your methods saved me from having
to completely clean out the garage. The team were good to work with
and show a commitment to ‘sorting out problems’. Well done.

Marlene and Don, Christchurch

The work done was superb. It finished so well
that my wife thought you hadn’t been there that day.
Excellent work and a relief for us.
