Lifting and strengthening of roads, taxiways and railway tracks

There is no need to stop traffic flows and create conditions for traffic jams

Each project is an exception that confirms the rule

       Ground engineering still plays an important role in identifying problems that usually affect the stability of major roads, bridges, tunnels, and public transport networks. In many cases, it responds to challenges that extend the life of these vital objects. Uretek often implements projects to restore a wide range of infrastructure without disrupting the daily operation of the transport network or affecting its users. Each project is unique in terms of size, location, and availability, and requires an appropriate individual solution.

       Below are some of the innovative and customized solutions that Uretek uses to restore transport infrastructure in the Russian Federation.

Maintenance of roads, highways, bridges, and interchanges

       Uretek has developed fluid resins used for solutions to repair the effects of ground subsidence affecting the entrances of bridge floors. Subsidence at the entrance to the roadway due to the use of heavy vehicles can cause the surface to sink deeper into the ground, disrupting the smooth transition between the entrance to the roadway and the bridge. The Uretek process is highly effective for raising and levelling joints and is achieved by injecting resin into the road base, filling all the available space to create a solid base for a smoother transition. The solution is cost-effective and fast to use, minimizing inconveniences in traffic movement.

        Fonterra's representative office in Russia, one of the largest companies in the Australian region, faced a drawdown on one of its busy transport routes. Unstable ground and voids under the 150 mm thick concrete slab caused approximately 100 m2 of area to settle by as much as 50 mm. Using geopolymer resins, Uretek ground Engineering was able to fill the voids and raise the slab back to the design level with minimal impact on the site's day-to-day operations.

Decommissioning of pipes under major intersections and airport runways

         Uretek materials can help road operators decommission back-up sewers or culverts located under road networks and runways. For example, Uretek was used to completely fill the 450mm diameter of a 390m long low-pressure gas pipeline under an extremely busy intersection in the Novy Urengoy area. The pipe was to be safely decommissioned as part of a project to upgrade transport links and update the streetscape under the direction of local transport authorities. The use of Uretek resulted in a significant reduction in time and costs, allowing transport to resume full traffic a week earlier than expected.

Stabilization of railway tracks and underground mines

         When two newly constructed elevators to the underground hall and platforms at the Museum's railway station on the Sydney city circle railway line required stabilization, Uretek used its resins to support the rock surrounding the Elevator shafts, eliminating voids at the junctions. This provided a safe, stable and reliable solution that caused minimal disruption to pedestrian access inside and around the train station.

          In another railway project, Uretek resin injection was used to fill large voids that formed under the track plates of the 8.8 km Kaimai tunnel, New Zealand's longest railway tunnel. A specially developed solution was applied to the slab(with pre-tension) in order to re-support the railway tracks. Early detection and responsiveness helped prevent extensive damage to the base of the tunnel, avoiding potential closure and costly replacement of the floor slab. In addition, this served to prepare the tunnel to accommodate larger and heavier trains in the future.

          Efficient and timely updates and maintenance are critical to ensure the longevity of transport infrastructure. A reasonable approach will also avoid unnecessary budget expenditures, limiting inconveniences and interruptions in the operation of public vehicles. In some cases, Uretek engineering solutions can also help reduce the need to replace large transport infrastructure.

Subsidence of transport infrastructure may be caused by the following factors:

  • Poorly compacted soil
  • Extra loads
  • Breakdowns and accidents of engineering communications
  • Regular moisture and temperature fluctuations
  • Influence of regular vibrations
  • Construction or pile work nearby
  • Biological processes in the soil
  • The presence of a dense or close planted trees
  • Seismic activity

Questions answered by Uretek:

  • What happens to a building or structure in general?
  • What caused cracks or displacement of structures?
  • Does it make sense to wait for improvements or changes, and what?
  • Is it possible to do cosmetic repairs and for how long?
  • What happens if you do nothing and in what time frame?
  • Will and what specific "shop-or-do-it-yourself" solutions help?
  • Will the "familiar foreman" be able to resolve the issue?
  • Is it possible and how to slow down or stop the process of destruction?
  • Is it possible to return everything as it was? What are the options?
  • When is it better and cheaper to start solving? Is it possible not right away?
  • How much does it cost to resolve the issue and what are the conditions for implementation?
  • What can be done for X rubles?
