As the population of Australia continues to grow, increasing pressure is placed on existing infrastructure assets. This is why employing non-invasive, economical asset repair and preservation solutions is critically important.
Mainmark’s ground improvement, re-levelling, void filling and slab lifting solutions remediate buildings and structures impacted by subsidence across the infrastructure sector.
Our innovative Teretek®, Terefil® and JOG technologies offer advanced site-specific solutions for revitalising ageing or damaged buildings, assets and infrastructure.
