Fiber cement board would not decompose into a lubricant. Need more strength? Use cement backer board. It will last indefinitely in any soil wet or dry.

The contractor said, use plywood. Not knowing of fiber cement board, I used plywood. Most could be pulled, but not all. The one in the really unstable soil has been log gone after 13-14 years. At 17,000# each movement has been slight in one. Nil in others. Wish I'd known about fiber cement board back then. OTOH it appears the minor movement is due to the soil and no room for back guys.
