Mainmark : Leaders in Advanced Ground Engineering and Asset Preservation Technologies

Mainmark offers unique, innovative solutions for rectifying ground engineering problems like sunken foundations in residential, industrial, commercial, civil engineering and mining situations.

For more than 20 years, Mainmark has built our reputation by providing cost effective and efficient solutions, great products, and excellent service. We have continuously challenged the traditional underpinning industry by offering some of the most advanced, accurate and non-invasive solutions for structure re-levelling, including resin injection techniques such as Uretek^®, as an alternative to concrete underpinning.

Mainmark is now proud to launch Teretek^®, a proprietary engineered resin solution that utilises an injection delivery method perfected by Mainmark after many years experience in fixing foundation ground issues and our knowledge of the unique local conditions. Teretek is a unique two-in-one solution that delivers both ground improvement and re-levelling. It increases ground bearing capacity, fills voids, and can mitigate soil liquefaction. This alternative method of underpinning is cost effective, time efficient, non-invasive, and reduces disruption. As part of post-earthquake remediation works in both Japan and Christchurch, we developed expertise in other technologies such as JOG Computer-Controlled Grouting and Jet Grouting. 

More recently, our expanded capabilities include: void filling and pipe abandonment with our Terefil lightweight cementitious fill; revitalising ageing infrastructure by sealing, protecting and reinforcing steel or concrete assets with ENCAP6; and rehabilitation of high pressure hoses and pipelines with the use of PrimusLine trenchless technology. Measuring the unique dynamic signature of any structure to determine the cause of damage, risk of further damage and overall structural stability is achieved with our world-leading STRAAM technology.  Read More >>
