Remediating road subsidence and keeping transport infrastructure functional
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 the UK 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.

Slab lifting process for roads
Small holes are drilled through the slab.
Multi-component strcutural 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 level correction methods for highway infrastructure
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 road 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.
