Puffed EPS beads – or bead foam – are not just the material that turns up in sixties-style bean bags. In fact, they’re more usually found as an important component in lightweight concrete. With EPS beads coming in at just 1lb per cubic foot compared to the regular weight of concrete at 150 lbs per square foot, combining the two produces a balance between strength and weight. Depending where and why the concrete is being used will determine the proportions of concrete to puffed EPS beads.
