We use 8" top (11" butt) CCA pressure-treated pilings, with the industry maximum treatment of 2.50 lbs/cubic foot retention. These pilings are driven as far into the ground as the river bottom will permit, with up to 15,000 lbs of force. Our 2x8 rough cross members share the same treatment, while our 2x8 joists/stringers utilize 1.00 or 0.80 pcf treatment. The decking boards utilize the common 0.06 pcf treatment.
We utilize galvanized 5/8" diameter hex bolts or timber bolts (similar to large carriage bolts) and double hot dipped galvanized 20 penny or 20D nails, which are hand driven. These nails are larger and rust far slower than our competitors' 16D and smaller nail gun nails.
