Above Ground Or Direct Contact For Dock Construction


reskinning a dock and looking to reframe a 20yr old deck. when talking with the HO I speak of direct contact PT but not sure of the benefits in waterside / dock construction.

is there? Is above ground better?

it's a constant level fresh water lake. protected cove = not a lot of wind induced waves onto the frame.

Re: Above Ground Or Direct Contact For Dock Construction


I googled this as being a minimum treatment level for freshwater contact:
*** minimum of . 60 pcf pressure treated

downside is I can't determine the levels of what's available at Home Depot.

I do buy my PT decking material from HD or Lowes b/c the materials I get dropped from the local building material supplier is very poor. #2 would be generous for some of the crap I've picked up...their RSC is descent though.

Can you look on the end tag. Usually says. With that said, I stay away from Home Depot PT. It's garbage.

Re: Above Ground Or Direct Contact For Dock Construction


The Home Depot here stopped stocking ACQ about a year ago and now only carries this brown stuff called MicroPro Sienna. Looks nicer but seems like junk. The treatment is only on the outside 32nd of the lumber. I know that didnt answer any questions...

Re: Above Ground Or Direct Contact For Dock Construction


I'd buy treated made for the coast, treated to 1.0 as you may have a hard time finding any .60 treated in Austin. There's a lumber co. in Galveston that does treating, forgot their name but, you could probably find them on the web.

The McCoy's along the coast stock it too so you might be able to get your local McCoy's to order you some. I've found the best one around Austin is out in Bee Cave.

The name came to me, Bayou City Lumber.

Whatever treated option you choose- Be sure to reseal the cut ends being that it can be expected to be 100% wet all the time.
