Spiral hydraulic and drainage team has a wide experience in the development of hydraulic and hydrology analysis throughout the different stages of a project including the design of the most adequate drainage solution (cross drainage and storm sewer systems) for multi-lane highways, freeways, toll roads and railways.
Thanks to our wide expertise and ability to adapt to the regulations and specific requirements of the different countries, the final design is compatible with all of them. Resulting in an adequate permeability of the infrastructures, minimizing impacts and avoiding any negative effects of the floodplain.
