Should pressure treated posts be set 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. Concrete should be poured around the post – no concrete under the post.
How do you make sure new posts stay plumb while the concrete is setting?
Hold a carpenter’s level against all sides of the post to ensure it is plumb, or straight up and down. Once you are sure the post is plumb, fill the hole with concrete. Take care not to disturb the post as you add the concrete. Check the post again with the level to make sure it is still plumb, and adjust if necessary.
Why deck posts should not be set in concrete?
A deck post should always be placed on top of footing, not inside concrete because it can break. Concrete tends to absorb moisture and wood expands when it gets wet, so these two factors combined will result in the wood breaking the concrete.
How long will a 4×4 post last in concrete?
A pressure treated 4×4 set in concrete should last about 20 years of more, depending on the soil conditions and drainage.
How long will pressure treated posts 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.
How long will pressure treated posts last in the ground?
3) A deck built with pressure treated wood will last a long time. Promotional literature promises lifelong performance for pressure treated wood. The Forest Products Laboratory and other research groups have shown that treated wood stakes placed in the ground for more than 40 years remain rot-free.
Is 2 feet deep enough for fence posts?
The depth of the hole should be 1/3-1/2 the post height above ground (i.e., a 6-foot tall fence would require a hole depth of at least 2 feet).
How do you attach something to concrete without drilling?
A simple fix might include an adhesive or adhesive-baked hook, while there are other fasteners like hard wall hooks and masonry nails. Powder-actuated fasteners and concrete nail guns are useful for supporting frames and providing a much greater hold.
Can you screw directly into concrete?
Concrete screws provide a quick, easy and incredibly strong way to fasten to concrete. And best of all, there’s no hammering required or anchor or shield to install. All you do is drill a hole and drive in the screw. That’s it.
Can deck posts sit on concrete?
First off, mark where deck posts will stand in the yard. There are several ways to set deck posts; we recommend attaching the posts to concrete footers above the ground. This helps to prevent wooden posts from rotting. Place a cylindrical concrete form in the posthole.
How do you keep fence posts from rotting in concrete?
Consider Adding Posts to Concrete
From here, you should fill the hole with about 6 inches of gravel. This will prevent rotting by ensuring that the post is kept dry when water makes its way into the soil. Place the post in the gravel, then fill with a batch of cement until it reaches the top of the hole.
Do fence posts need to be set in concrete?
First rule, gang: Do not set wooden posts in concrete. Look, no matter what preventative steps you take (and I’ll get to those), eventually wooden posts rot, and eventually you’ll have to set new ones. Not only does burying them in concrete make for more work down the line, it actually can speed up the rotting.
How do you stabilize a post?
Here’s what to do:
- Take out adjacent fence construction.
- Cut or buy a few tapered (top to bottom) surveyor stakes about 24 inches long.
- Drive a stake into the ground next to the post or next to the concrete.
- Pull the stake.
- Fill the hole with water and level the post.
- Add dry premixed concrete to the top of the hole.
