Every year, more and more bridges, roads and highways are constructed to meet growing demands. However, this new construction or expansion of infrastructure may end up being built over loose or soft soil that does not have the ability to support the associated loads. So how do you reduce the vertical stress of these projects on the soil below? One solution is using expanded polystyrene (EPS) geofoam, a lightweight foam plastic that’s manufactured into blocks, has a unit density that can be roughly as low as one pound per square foot, it’s an extremely lightweight alternative to soil that’s nearly 100 times lighter than most soils, suitable for soft soil remediation, slope stabilization, lateral load reduction on retaining structures, structural void fill, and buried utility protection. Traditional earthen fills characteristics vary from one excavation source to another, to address this limitation, geosynthetics like EPS geofoam, are produced under controlled conditions and yield predictable and consistent engineered values, which can simplify design and construction and eliminate testing costs.
