I'm surprised there aren't more well-engineered products, and that they aren't considerably cheaper (due to mass selling and production).
The only thing that comes to mind are the dry-core sub flooring panels that either have a plastic or foam layer on them...
Maybe we should start by making foundations and basements out of something other than cement? Something just as strong and easy to work with, but water and thermally resistant.
I hear there's millions of tonnes of plastic ending up in the oceans every year...let's filter it out and make lego building blocks out of it, in place of cinder blocks.
