Pond Boss Forums POND CONSTRUCTION Renovating a Pond or Lake? Building a new Dock

I have used white oak for cattle catch pens and for flooring on equipment trailers. It is preferable in these uses because it takes a pounding and distributes weight better than pine boards. Seems like it lasts @ 10 yrs or so on catch pens untreated. It is VERY hard to nail and sometimes subject to split. Hard, high quality screws would be the way to go. Don't skimp on the wood treatment afterward. I have had good luck with oil based. Your spacing should be the same though as if you were using pine boards.
