Wood Decks in East End, OH

On the narrow strips between the hillside and the river in the East End (ZIP 45226), decks often sit low, a step or two above ground that stays damp for much of the year. On a deck like that, the lowest boards, the step and the edge nearest the soil face harder conditions than most decking is made for.

Acetylated wood was developed for exactly those conditions. Fast-grown pine is soaked under pressure in acetic anhydride, which changes the wood so its cells stop drawing in water. With that appetite gone, decay fungi have nothing to work with and the wood hardly swells or shrinks. Unusually for a softwood without a preservative, it is rated for ground contact, so it can go where ordinary decking should not.

On a low riverside deck that means the whole floor can be one material. The boards over the damp band near the ground, the bottom step and a border that sits close to soil are the same pale, even timber as the rest, instead of a patchwork of different products for different heights. Because it moves so little, the gaps stay open even through the wet months, which keeps air moving under a deck that has little room beneath it.

It carries a trace of acidity from the process, so every fixing is stainless, as the maker requires, and it takes a light finish evenly if the pale color is to be kept. Left bare, it weathers to a soft gray. The frame below is treated pine rated for ground contact. Built that way, an East End deck close to the river stays sound where it meets the damp.
