Keeping New Zealand’s roads operational with minimal disruption
Since 1989 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. We also avoid 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:
- Filling 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.
- Providing targeted ground improvement to weak subgrade soils.
Roads
Raising subsided pavements to re-establish design levels, drainage or camber gradients and to restore a safe and comfortable ride for motorists.
Bridges
Void filling, re-supporting, and raising bridge approach and relieving slabs. To provide targeted ground improvement to weak sub-grade soils.
Culverts
The filling of voids directly beneath pavements to reconfirm support and limit deflection and deterioration.
Slab lifting process for 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.

Non-Invasive
Repairs are performed without the need for excavation, extensive road closures or traffic disruption.
Cost-Effective
Compared to traditional methods, our solutions are more cost-effective.
