Can pressure treated wood sit on concrete?
Can pressure treated wood sit on concrete?
Can pressure treated wood sit on concrete? – Quora. YES. Any exterior concrete that is in contact with earth may wick moisture. Thus, it is required to place pressure treated wood directly against the concrete if one wishes next to build off that concrete with untreated wood.
Do pressure treated posts rot in concrete?
Simply setting the posts in concrete does create a condition that will accelerate rot in the bottom of the posts. With pressure-treated posts, the rot will be slow. This allows any moisture that gets between the concrete and the bottom of the post to percolate through the gravel and away from the bottom of the post.
Do you need pressure treated wood in a basement?
Basement Masonry Walls Pressure-treated wood is required whenever you attach framing lumber or furring strips directly to concrete or other exterior masonry walls below grade. Because basement walls are hidden behind drywall or other wall covering materials, the wall framing members are not exposed to light and air.
How long will a pressure treated post last in concrete?
A PT post will last a long time in concrete, maybe 5 to 10 years in soil alone. I suggest you embed the post in concrete, trowel a peak around the post so water runs off, and don’t let the PT post come in contact with the ground.
Do you need a vapor barrier on concrete?
You’ll typically need a vapor barrier if you’re installing flooring over concrete. Therefore, in high-humidity areas, moisture will move to a relatively low-humidity area, even through concrete. This way you can stop the vapor drive of water upward to your floors, protecting them from any damage (source).
What is the best foundation for concrete?
Poured concrete foundations are by far the most popular; about two-thirds of all residential and commercial basements are poured concrete. In most cases nowadays, rebar or metal rods are installed for added strength before the concrete is poured.
How long will pressure-treated wood last outside?
It depends on the climate, the type of wood, its uses, and how well it’s maintained. While pressure treated poles can stay up to 40 years without any signs of rot or decay, decks and flooring might only last around 10 years.
How long will a pressure treated 4×4 last in the ground?
A pressure treated 4×4 set in concrete should last about 20 years of more, depending on the soil conditions and drainage.
Can you use pressure treated wood for a foundation?
Permanent wood foundations use FDN treated lumber. Pressure treated wood rated for ground contact is not to be used for foundations. The preservative chemical retention for ground contact wood is less than that of FDN treated wood. In addition the wood used in PWF does not contact the ground.
Do you have to use pressure treated bottom board for concrete slab?
Installing framing members on a slab requires use of a pressure treated bottom board to avoid wood rot. Concrete slabs will wick moisture between the underlying dirt base and the wood members sitting on top of the slab. If untreated wood is used for the bottom board, the high moisture level will promote rapid decay.
How do you attach pressure treated wood to concrete?
There are many different ways you can adopt to attach a pressure-treated piece of wood to concrete. Each one follows a similar process: open/drill a hole in the concrete and wood, then insert the fastener piece and tighten up. This is not as easy as it sounds, but it won’t be too challenging, either.
Can you use PT wood in a basement?
Most building codes require PT wood that will be in contact with basement concrete floors. So the bottom plate of a 2×4 wall and code requires the use of fasteners (galvanized) approved for use with PT wood.

Can you use pressure treated wood in a basement?
Wood pressure-treated with ACQ preservatives may be used inside residences as long as all sawdust and construction debris are cleaned up and disposed of after construction. 2. no vapour barrier / gasket / separation between the concrete and the wood = potential mould problem down the road.

How much does pressure treated concrete wall cost?
Lumber yeards are getting about $0.22 per linear foot at the time of this writing. This means an additional $22.00 / 100 feet of wall. Increased Installation Time. Fastening the pressure treated board first requires additional time because you must address each portion of the wall twice.
