Does anyone have any experience using Foamed Glass Aggregate as a foundation subbase, that is, the layer of crushed stone directly beneath a concrete footing? Looking for any experience or insight as to considering FGA as an alternative to conventional foundation subbases for uniform bearing loads.

For highways products in the UK, Type 1 material is oftern specified. Type 1 material has a list of criteria that it needs to pass, Loss Angeles, soundness etc. I would like to see what characteristics Foamed glass aggregate has before I say its good enough for a starter layer.

I would recommend contacting the manufacturer with your question. They have lab testing and examples of projects they have used it on.

Surely only useful as thermal insulation?

Foam glas is usually laid as sheets under a base or on top of a base under the floor.

Why is this being proposed?
