Across the sector, asset owners within the public works sector face similar challenges: maintenance costs are rising, but funding isn’t. Whether it's roads, pavements, slabs, or retaining structures, the gap between what’s needed and affordable continues to widen. This situation is causing stress, with public works authorities having to balance making the right decisions for the asset, meeting the expectations of multiple stakeholders and working to tightening budgets.
This presentation explores how non-invasive ground improvement and void-filling technologies offer a smarter, more cost-effective alternative to traditional remediation methods. Mainmark’s polymer injection solutions are being used to address a wide range of surface and subsurface issues, including road settlement, concrete slab deflection, retaining wall movement, and subgrade failure.
These methods are non-invasive, fast to deploy, and require no excavation, which means minimal disruption to road users, commuters, or nearby operations. Projects are typically completed in hours or days, not weeks, with significantly lower cost and far fewer safety risks. Importantly, they meet the strictest engineering and regulatory standards.
Our technology is trusted in some of the world's most safety-critical environments, including international airports, major freight and passenger rail networks, and essential infrastructure such as water and wastewater treatment facilities.
We will present recent case studies from across Australia and New Zealand covering a range of assets, including pavements, transport corridors, bridge abutments, and aging concrete infrastructure. Each example will highlight the commercial, technical, and operational benefits compared to traditional approaches.
As infrastructure networks continue to age and funding pressures grow, there is a critical opportunity to adopt modern, engineered alternatives that deliver better performance at a lower whole-of-life cost. This presentation provides practical insight into a proven method that helps asset owners extend the life of existing infrastructure more safely, faster, and without compromising the asset's long-term sustainability.
