Water Resistant Wood

Keep seeing references to new(ish) wood products that use natural wood and an alternative process to pressure treating and produce a better performing material. This may be an option for outdoor structures or a water table experience where we’d like to clad a stainless or concrete basin with a more natural material or perhaps even build a table out of wood (was that Steve Langsdorf I just heard groaning?).

If the specs are true, this material is substantially better than pressure treated. Here’s two products that are getting a lot of press the last few years:
