Hi everyone.... need some suggestions please.... How would you guys create the subbase for this easement incline. My original thought process was to use tape or cardboard webbing, joint compound and paper towels. But before I start slopping the stuff on, I am curious if there is a better way to be doing this. I will be using Kato Unitrack on top of this which I believe I will be able to blend in with ground cover etc. For areas where I will be creating small mountains and maybe a tunnel, I plan on use the pink foam as the base. Thanks for your help.
