Universal Construction Foam can help you as a professional engineer; identify exactly what you need to meet ASTM D6817 – the “Standard Specification for Rigid, Cellular Polystyrene Geofoam’. Geofoam is a strong cellular plastic material. The density that you require is based on the control you need for project loading conditions – as well as considering project costs. On our online learning center, take a look at the full explanation behind Geofoam as well as the product datasheet. Specifications from compression resistance to flexural strength are all listed so you can meet the building standards specified for your geofoam construction project.
