As a load-bearing, thermal insulating substrate under a slab, glass foam offers a combination of properties that no other material can offer. GLAVEL replaces the aggregate layer (drainage/capillary break under slabs), the frost barriers and provides thermal insulation from the soil. This provides a simple, thermal bridge-free soil structure for a thermally separated slab in one step.
Foam glass gravel can also be used for road construction on unstable ground (marshy ground, permafrost, or marginal zones) and as fill around pipelines to provide stabilization and insulation.
