URETEK® RESIN INJECTIONS OFFER THE BEST SOLUTION FOR THE RAILWAY SECTOR, WITH A MINIMALLY INVASIVE, FAST AND WASTE-FREE TECHNIQUE.
The high-speed line linking Paris Austerlitz with Bordeaux Saint Jean suffered a deterioration at the base of the railway following the construction of an underpass. There had been instabilities manifested on the surface by a sinkhole.
To solve this problem used our innovative Deep Injections® technology that allowed us to reinforce the decompressed soils of the subplatform with injections of expansive resin. This solution allows us, thanks to our resin injections, to consolidate the foundation ground, improve its mechanical and hydraulic characteristics, eliminate differential seats and recover the bearing capacity.
In this intervention, an area of 120 m² was covered, injecting the resin up to 3 m deep under the railway. It was carried out in a total of 15 hours, divided into 3 nights of work, adapting to the railway traffic schedule. The flatness checks carried out by SNCF confirmed the effectiveness of the intervention carried out.
All our interventions are controlled in every moment with a laser monitoring system that allows us not to suffer any incidence in the altimetry of the tracks.
With Uretek® resin injections we offer the best solution for the railway sector, with a minimally invasive, fast and waste-free technique.
