Wandered over from the sawdust sandpile. I’ve been asked to laminate 18″ tall by 6.75″ wide beams for bocce ball court. Bottom on concrete footer, outside partially buried, top covered with copper or aluminum cap. Will be sprinkled daily to maintain the clay surface and surrounding grass. Buried surfaces will get epoxy paint.
Wondering what wood might last in this environment. Only suggestion from local lumber yard marine plywood, and I don’t know if it would last with ground contact. If used, customer wants it covered on exposed face with hardwood. Would mahogany be rot resistant if a 1/2″ or 3/4″ x 18″ board were laminated to the marine plywood?
Is it possible to get kiln dried treated lumber? Are there any other wood suggestions?
Thanks for your suggestions.
