Sorry on my bad English grammar-Thanks!
I want to bulid fiberglass track sandwich with polyuretan foam thickness 2 cm. Track will be 6 meter length and 90 cm depth. Track will be located on flat hard stand and people will walk over track.
My question is, how much layer of fiberglass I must put over foam? Track must be hard enough to hold two or three pople.
Note: I want to use less material as possible
