Glavel is a structural solution for soft soil applications or projects that require lightweight fill to alleviate settling concerns. At 9.8 pounds per cubic foot, Glavel reduces structural load when compared to crushed stone aggregate. Glavel is non-leaching, closed cell, and allows for drainage. The high compressive strength of Glavel allows it to be used underneath significant static and dynamic loads, such as roadways, embankments, and retaining walls.
