Mainmark offers unique, innovative solutions for rectifying ground engineering and asset preservation problems 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 as an alternative to concrete underpinning.


In 2017 Mainmark launched Teretek®, a proprietary engineered resin solution that utilises an injection delivery method perfected by Mainmark 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.
