I'd like to build a retaining wall/large planter around our shed to create some scenery and block the "crawspace" underneath the shed. Should we use a moisture barrier against the exterior walls of the shed for additional protection against rotting (shed is wood siding), or should the stones for the planter provide sufficient protection?

  • What did you end up using as a moisture barrier? – eaglei22 May 15 '18 at 21:30

If the planter is going to be in direct contact with wood, absolutely. Concrete is porous and it will be permanently saturated with water.

  • Many thanks. I'd mark the answer as helpful but I guess I don't have the reputation to do so yet :) – Tim Brennan May 9 '16 at 2:21
  • Figured out the check mark! Thanks again for the input. – Tim Brennan May 9 '16 at 2:49
