Infrastructure

Road subsidence

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.

Bridge approaches

Void filling, re-supporting, and raising bridge approach and relieving slabs. To provide targeted ground improvement to weak subgrade soils.

Pavements

Raising subsided pavements to re-establish design levels, drainage or camber gradients and to restore a safe and comfortable ride for motorists.

Culverts

The filling of voids directly beneath pavements to reconfirm support and limit deflection and deterioration.

Keeping the UK’s roads operating with minimal disruption

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
