Ultra-lightweight aggregate provides solutions for the challenges of today’s infrastructure projects. Foamed glass aggregate is ideal for projects that require fill to be placed over soft compressible soils or over areas with underground utilities. Large embankments can be built with low net surcharge due to the low unit weight and high friction angle of UL-FGA.
• Lightweight backfill for sensitive utilities
• Bedding layer for utilities on soft
• Insulating backfill for frost protection
• High friction angle creates soil arching to
further reduce loads on utilities
• Heat resistant up to 800° F
