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 around the world and now in the UK. It offers a unique method for addressing bearing capacity issues and voiding that is common in aged infrastructure foundation systems. We can raise, re-level and re-support public roads and bridges with little interference to traffic and operations.

Bridge subsidence can be remediated using our  Teretek® engineered resin injection solution, correcting concrete roads and pavements, bridge approach slabs, bridge abutments, motorways and road culverts.

Our advanced technologies are time-efficient, cost-effective and non-invasive and full use of the road or bridge can be maintained during stabilisation. Work can be carried out one lane at a time, overnight and in between rush hour traffic if required. Vehicles are also able to drive over the remediated area almost straight away.

Mainmark’s stabilisation methods require no excavation and work can be successfully completed in just a few days. We have achieved a complete bridge lift of a maximum of 1300mm.

Some of the more common applications for bridge subsidence remediation with resin injection are:

• 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.
• Providing targeted ground improvement to weak subgrade soils.
