I'm in the middle of a project where we removed a rotting deck (termites) and are in the process of installing a raised patio with pavers. The fill the contractor is using for the paver foundation is a combination of leftover concrete pieces and dirt.
I am aware that wood siding should never be below grade nor be in direct contact with soil, and I keep stressing that to the contractor, but he keeps assuring me that this approach of installing a waterproof barrier over the old siding that would be below grade, plus an aluminum barrier on top of it, will prevent any moisture or termites from getting to the siding, and into the house frame.
Is this correct? Everything else I've seen says ALL SIDING SHOULD BE 6" AWAY FROM GRADE but I haven't seen anything about anyone using an aluminum barrier. Note that the lower edge of the siding is still exposed beneath the aluminum.
UPDATE: Thanks everyone for the input. The contractor is convinced that the original way (house siding as the 4th wall) is fine and they've been doing it that way for 15 years, but they ultimately let me dictate what I wanted (at a small cost): a retaining wall is being installed about 1/2" away from the house, after that lower siding panel has been removed and flashing installed from the (new) lowest siding plank to the foundation. The (now) bottom siding panel will sit about 3" above the top of the pavers.
