PS geofoam has emerged as a popular material in construction
projects due to its lightweight and versatile nature. Used for various
applications in civil engineering, this expanded polystyrene foam offers
excellent insulating and structural properties. However, when exposed
to hydrocarbons such as those found in oil, gasoline or other chemical
substances, it can deteriorate over time. To counter this issue, reinforced
EIA (ethylene interpolymer alloy) geomembranes have been employed
as a protective barrier. In this article, we will delve into the use of EPS
geofoam and explore methods to shield it from the damaging effects of
hydrocarbons using reinforced EIA geomembranes.
EPS geofoam, short for " expanded polystyrene geofoam, " is a lightweight
cellular plastic material that is manufactured from expanded
polystyrene beads. With its high-compressive strength, low weight and
excellent thermal insulation properties, it has become a popular choice
in various geotechnical and civil engineering applications. Common
uses of EPS geofoam include road construction, bridge abutments, slope
stabilization, and lightweight fill for embankments.
EPS geofoam's lightweight nature creates significant advantages in
construction projects where traditional soil and aggregate materials
may be heavy and cumbersome. Its low density combined with highcompressive
strength makes it ideal for reducing loads on underlying
soil and structures, thereby minimizing settlement issues. The thermal
