How To Brace A Post In Concrete?

Can 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 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.

Does filling a post with concrete make it stronger?

Filling with concrete is not as effective as increasing wall thickness or changing the shape, but it’s a proven technique.

Is 2 feet deep enough for fence posts?

Project Instructions



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 I put a post in the ground without concrete?

Procedure:

1. Find a concrete surface and lightly tamp your digging iron against it.
2. Remove the turf and topsoil from the site of the post.
3. Dig the hole putting the displaced earth onto the tarp.
4. Pour 4 inches of gravel into the hole.
5. Place the post in the hole.
6. Add another 2 inches of gravel around the base of the post.

Can you put dry concrete in a post hole?

Fast-setting concrete is ideal for setting posts because there’s no mixing—you simply pour the dry concrete from the bag right into the hole, then add water.

How do I keep my post level while concrete dries?

Fill the hole up to a depth of 8 inches from ground level with 1/2-inch drainage gravel. Use rough-cut gravel with sharp edges. It will hold the post better than smooth rock.

How do you secure a broken fence post?

1. Support the fence with lengths of timber on either side whilst you make the post repair.
2. Use a shovel to dig a hole around the base of the fence post on the side where the concrete repair spur will go.
3. Place a concrete spur post in the hole against the remains of the post.

How long will a pressure treated post 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.

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 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.
