I understand that the Hardi-board planks for siding are not supposed to be installed in the splash zone near the ground as they wont stand up to constant wetting. OTOH I built a raised bed by taking what I assume was Hardi-backer or the equivalent, cutting a 4' x 8' sheet into 1' x 8' strips, overlapping and bolting the ends, and making a 10' diameter by 1' high ring. It's been a couple of years and it has not failed yet. I can't imagine worse conditions for a material to endure except we don't get the freeze-thaw cycle.
