Our club is about to embark on major renovation of a large modular layout. We will be replacing old foam roadbed (not Woodland Scenics) which has seriously deteriorated with something. Some argue for cork, others argue for Woodland Scenics foam which is manufactured differently than the stuff which failed. Whatever we use has to stand up to the abuse of movement and temperature shifts. I'm interested in hearing about the durability of roadbeds on modular layouts that are more than 10 years old and particularly with modular layouts using Woodland Scenics roadbed.
