Keeping Australia’s roads operational with minimal disruption
Keeping transport infrastructure functional
Since 1995 Mainmark has been providing fast, non-disruptive & cost effective solutions to remediate subsidence beneath road surfaces and bridge approaches.
Our technologies offer distinct benefits in addressing issues like bearing capacity failures, voiding, and loss of support often found in aging infrastructure, all while avoiding the expensive costs and road closures typically associated with sub-grade and pavement removal and replacement.
Some of the more common applications for the remediation of roadways 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.
Raising Subsided Pavements
Our Teretek® Resin Injection technology can raise, re-level and re-support subsided pavements.
Watch how our non-invasive, cost-effective technology raises and re-levels a roadway with minimal disruption.
The roadway can be re-opened to traffic as soon as the repair is completed.
Slab Lifting Process
For Rigid & Flexible Pavements
Small holes are drilled through the slab.
Multi-component structural resin is injected. It expands immediately, filling any voids and compacting the substrate.
After re-supporting the slab, continued injection raises it, guided by the laser level.
The treated pavement sections are returned to full operation immediately after the repair work, and no curing time is required.
Features & Benefits
Mainmark’s Solutions & Technologies
Our technologies have fast curing times and treated areas can be used immediately or without the delays compared to traditional repair methods.
As soon as the repair is completed, the roadway can be re-opened to traffic and full use.
Repairs are performed without the need for excavation, extensive road closures or traffic disruption.
Compared to traditional methods, our solutions are more cost-effective.
