Mainmark are experts in building and infrastructure remediation and repair.

Our solutions offer sustainable and responsible outcomes that focus on preservation rather than replacement. This reduces the need for invasive, lengthy traditional underpinning or asset replacement works, that create environmental challenges in the methods used.

For over 25 years we have specialised in advanced, non-invasive soil stabilisation, ground compaction and foundation repair solutions to improve support for homes, buildings, roads, bridges and other structures affected by subsidence. We treat the ground beneath these structures to raise, re-level and re-support them cost-effectively. We are Licenced Builders and certified to ISO Quality, Environment and O&HS standards.

The use of geophysical testing for Mainmark technologies

When it comes to the use of Mainmark’s technologies, a common question we encounter is “how do you validate your work?”. As ground engineering solutions do not always have visible results, validation testing is an integral part of any project. Geophysical testing provides a suite of tools used in geotechnical engineering to identify the soil

Challenging conventional underpinning

Conventional underpinning using steel and concrete has long been the go-to solution for supporting or strengthening the foundation of an existing house, building or structure for engineering and construction professionals. However, alternative more innovative solutions are challenging the status quo. These methods of stabilising and lifting structures have been in use for more than a

How climate change may affect your property’s foundations

Climate change is often associated with cataclysmic weather events and temperature changes but it can also have more subtle, long-term effects on our homes. Scientific research over the decades has revealed that the earth’s average temperature has gradually increased due to the greenhouse gases that are trapped in the atmosphere. This is particularly noticeable in

“I’m a Sales Director for a publicly listed US software company so I know a thing or two about good customer experience. I was incredibly impressed by R__ today. He essentially walked in my door and said that from reading the engineering report I’d provided and his initial look at the building, he didn’t believe that we needed your services. He then spent nearly 40 minutes looking at the various issues we are facing and gave us his practical, honest advice about how we should approach things.

I won’t bother you with the details, but I was seriously grateful for his time and everything he said makes total sense. Although we won’t need your services in the near term, I will have no hesitation in coming back to Mainmark if things change. As someone who has spent 30 years selling a variety of services, it’s always great to meet someone who knows their stuff and is just focussed on helping the customer.”

“I just wanted to let you know how extremely happy we are with the outstanding service provided by Mainmark from beginning to end. It was such a pleasure to have a friendly and professional person such as yourself attend for a quote and then to experience how receptive you were to our need to get the job done before Christmas. You could not have two happier customers. We would recommend Mainmark to anyone.”

“What a professional job! The staff were so nice! They arrived on time, were organized, excellent with Boston the pug, clearly took a lot of care with their work, totally recommend! The house is soooo level, and the doors all shut.”

Valerie, Lower Hutt, Lower North Island, NZ. November 2021.

“I am a chairperson at a complex in Aspley and was referred to Mainmark. The person that came and saw us was knowledgeable, explained that the job probably wasn’t for them due to the cost of having to bring the truck and the equipment for a very small job. He spent 1.5 hrs taking measurements and readings to help us get a better picture of the small amount of movement in the dwelling, then sent us a drawing of the particular dwelling floor plan with the level readings for future monitoring. Gave us some great advice and there was no charge for his time. We were suitable impressed and will certainly engage their services if we have any further movement issues to advise us what the next step would be. Thank you, it was refreshing (a) not to receive an invoice (b) the amount of time he spent there at no cost to us as initially it was to obtain a quote if we had decided to proceed with any work.”

Vicki, Aspley, QLD. November 2021.

“Please pass on my thanks to all concerned. I can not express enough my satisfaction with all concerned.The results exceeded my expectations and Steven and the crew were thoughtful, respectful and professional. I will be recommending your service widely.”

Rob, Newstead, TAS. Oct 2021.
