Multi-linear drainage geocomposites for railways
June 1st, 2022
FIGURE 1 Multi-linear drainage geocomposite under railway embankment In civil engineering, drainage systems are traditionally made with granular material layers and perforated collector pipes. The use of drainage geocomposites became more common 30 years ago with the development of products that met the specific requirements of each application. Moreover, the geocomposite is cheaper than the […]
