The solution offers a qualitative repair of culverts with a limited impact on the infrastructure geometry (most important factor for these assets from a regulatory point of view). The solution relies on an innovative technology that allows optimized design due to outstanding material performances. The objective of the solution is to offer public works owners and road/motorway managers a lasting solution that has less impact on the environment, allowing them to rehabilitate buried metal culverts that are heavily corroded and at the end of their service life. The solution offers the opportunity to restore them to their full capacity taking up traffic loads, to extend their residual life by 100 years, while preserving their passage clearance in order to ensure their primary function, which is to provide a road or agricultural passage and/or to ensure the ecological continuity of fauna and flora and/or the continuity of the flow of watercourses without increasing the risk of flooding.
The Environmental Benefits
- •Reduction by 90% the steel bars reinforcement
- •Reduce thickness of solution by 70%
- •Reduce by ~60% the use of freshwater
- •Reduce by 64% the Global Warming Potential vs mainstream solution
- •Reusability of current structures instead of A) demolishing and building new one or B) repair every 15/20 years
- •Produce 95% less waste
The Financial Benefits
- •Elimination of any maintenance cost associated and extension of service life to 100 years - For the alternative, there is maintenance costs every 15/20 years and full repair of the asset every 35 years
- •The lower consumption of materials allows reducing the duration of the jobsite by 50% and indirectly all associated costs generated by a jobsite (staff, equipment, mobile offices, energy, water...)
