Some squares here now have a floor made of pebbles mixed with some kind of (epoxi?) resine instead of a floor made of concrete or just soil. Do you think that it's possible to use lignin as the glue instead?

Is the mix with lignin waterproof?

Thanks for the question! I do not believe that Lignin is the right "glue" in this case. It is quite water resistant, but to bind properly, it needs a certain amount of finer particles in the mix. If You choose gravel instead of pebbles, it should on the other hand work fine.
