Regular maintenance and replacement of aged infrastructure is essential for roads to sustain heavy traffic and avoid significant disruptions and safety hazards caused by land subsidence and surface cracks. Our Teretek® Resin Injection has been qualified, tested, and adopted by road authorities in Australia and across the world. It offers a unique method for addressing bearing capacity issues and voiding common in aged infrastructure foundation systems while avoiding high costs and road closures associated with sub-grade and pavement removal and replacement.

Since 1989, Mainmark has provided its well-established Teretek® Resin Injection technique as a fast, non-disruptive, and economical solution for re-levelling subsided pavements and structures and strengthening subgrade soils associated with pavement failures.

Some of the more common applications for the remediation of roadways with Resin Injection are:

• The filling of voids directly beneath pavements to reconfirm support and limit deflection and deterioration.
• Raising subsided pavements to re establish design levels, drainage, or camber gradients to restore a safe and comfortable ride for motorists.
• Void filling, re-supporting, and raising bridge approach and relieving slabs.
• To provide targeted ground improvement to weak subgrade soils.
