I have a wood floor in the snowmobile shop.Its built as a post building.Double layers of blue tarps were laid down and pinned thru the grommet holes with landscape spikes and fender washers. A floor joist system was built between the gable walls from 2 x4 treated, stood on edge at 16"oc.the space and between them was filled with fine afton stone,leaveing about 2 1/2" between the stone and the top edge of the 2x4's.We laid 2" foam sheet in the cavities, then covered it with 5/8" treated plywood laid on a 45% bias to the joist. They were glued and nailed with ss ring shanks from an air nailer.A layer of 40# felt went down,then 3/4" treated plywood laid at 90 deg to the joists , ring shank nailed as well.We spaced the sheets 3/8" and literally poured the underlayment adhesive to the joint,then closed it up to 3/16" and nailed it.After a week or so i rolled an obscene ammount of a clear wood sealer made specifically for treated wood on it untill it qiut takeing it.A month later it was ready to work on, and has seen disturbingly abusive service ever since. It does have a sled hoist intalled on it,and the machines are totally cleaned with hot water weekly.I just drilled a dozen 1 " dia holes in it where the water was ponding and problem solved! It looks pretty nappy now,12 yrs later,a lot of oil,dirt,grease and hot water soaked into it! But its still solid and being readyed for another season!
