I don't know much about this GEOCELL foam glass gravel stuff but the more I look into it the more I think it will suit me just fine for my future garage/workshop.
It looks really straight forward. No trenches (but a deepish hole to dig). No EPS to cut. NO DPM it seems as well, and most of it I reckon I can do myself.
I'm sure there are catches that I'm unaware of (like price maybe?) what am I missing? Is this GEOCELL foam glass gravel a good option for a garage/workshop foundation?
