I have a friend who is a cement contractor. Each winter he rebuilds his damaged forms. So i bought a 4x8 sheet of Dura Form from him. 16 ply 1 1/8 inch thick. Two of the 16 plys are some form of plastic. Tough as nails. I could park a tank on that bench. Dura Form is a company in Madison Wisc. If you so inclined.
