I went to the source just to clarify here's what I got back from Steve technical engineer at HomasoteBy improved I mean if they’ve fixed the moisture/swelling issues since the early stuff.
I can guarantee it wasn’t so water proof early on, I definitely remember homasote roadbed sponging up.
Much like particle board does.
Good to know it’s better now.
edit: This is reminding me of a club I was in using kittie litter for ballast. Wow, next morning after a work session the track was floating two inches above the layout!
so whatever they were using not true Homasote
Mike,
Due to the presence of paraffin wax in the mix, Homasote is considered to be slightly hydrophobic in nature. While that does not make the substrate “waterproof” it does give it a very good relationship with water. Incidental contact with water will never be an issue.
Homasote would never have “sponged up” water. The product has been made in the same way since we first made it in 1909. There have, however, been other fiberboards on the market over the years that are made from wood fibers in an adhesive matrix rather than from recycled paper and wax. These product do tend to absorb water. These other fiberboards often get called “homasote” generically as Homasote is the “Kleenex” of fiberboards.
I’ll be pleased to discuss this in greater detail. Feel free to give me a call here at the Homasote Tech Desk. We appreciate your interest in our product.
Regards,
Steve
