Will concrete stick to pressure treated wood?
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.
Can concrete touch wood?
Wood in direct contact with concrete, and the dampness often found there, will rapidly decay. To avoid this, use pressure-treated lumber. This indicates that the wood contains a quarter of a pound of preservative per cubic foot, which is sufficient for use against exposed concrete, outdoors as well as in.
Do pergola posts need to be buried?
A pergola doesn’t need footings or concrete to support itself, but its posts will need to be buried into the ground or anchored with heavy-duty concrete anchor bolts to prevent them from toppling over in high winds.
How do you stabilize a pergola?
Some potential options:

Can you pour concrete up against wood?
This would separate the concrete and the Tyvek, and thus isolate the wood from the slab moisture. I know from 2 years’ research in the field of ICF construction that putting concrete directly up against untreated wood is an absolute no – no as far as long-term durability goes.
How do you adhere wood to concrete?
One of the best ways to secure wood to concrete is also the easiest: epoxy glue. There are certain epoxies that are manufactured specifically for wood-to-concrete use, and you can try using one on its own or combined with nails or screws.
What can I use to seal wood to concrete?
I recommend using an exterior silicone formulation for concrete or a high-quality polyurethane sealant. Both will stick well to the wood and the concrete. Acoustical sealant is a better, albeit slightly more expensive, option. Caulk often works best at a slab-wall transition.
