GLAVEL is an excellent substitute for infrastructure projects that specify light-weight aggregate. Foam glass gravel is a highly stable and versatile product that has been successfully used in construction of buildings and infrastructure in Europe for over twenty-five years. Foam glass gravel is manufactured from cleaned recycled glass and is a lightweight aggregate proven to be an excellent product with multiple applications: building insulation, green roofs, bulk fill, frost heave insulation, and embankments.
