Embankment Drainage - Rail Embankment, Pozidrain, Certaldo Poggibonsi Railway, Italy

by ABG creative geosynthetic engineering


In 1850 the Siena to Empoli railway line became a central part of the wine making industry. After being destroyed in WW2 it was rebuilt to modern standards. 20KM of new embankment required construction to upgrade the railway to meet current requirements. This required 500mm starter layer requiring thousands of cubic sqm of stone. ABG Pozidrain was proposed as a starter layer. The 7mm cuspated drainage layer has six times higher flow capacity than traditional stone. In addition each delivery covered 9500sqm meaning a 400 lorry reduction on the project. This subsequently reduced the carbon footprint on site.
