Should I use concrete for fence posts?

Concrete is the most secure material for setting fence posts, especially if you have sandy soil. Using premixed concrete rather than dry concrete will ensure ultimate security. While concrete is sturdy, it lacks the drainage of gravel and can trap moisture, ultimately leading to rot.

Will fence posts rot in concrete?

A: Actually, your point is well taken. 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. The concrete at the top should be sloped away from the post to grade level to avoid water pooling around the base.

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.

How long will a treated 4×4 post last in the ground?

The length of time that you can keep a treated post in the ground depends on a few different factors. Generally speaking, in the optimal conditions, it can last as long as 40 years. More commonly, though, it will last around 20 years.

Can I pour concrete around deck posts?

the concrete around the post at the top (slab or patio) will cause two problems, 1 it makes a weak spot that will crack or 2 as the cocrete expands and contracts with the weather it could shear the post and cause the structure to fail. Yes, I agree.

What should I put between wood and concrete?

In most cases, either pressure-treated lumber or naturally durable lumber (defined by the IRC as the heartwood of redwood, cedar, black locust, and black walnut) is acceptable. In some cases, separating wood from concrete with a water-impervious membrane or vapor retarder is all that’s required.

How far apart should 4×4 deck posts be?

6 feet

Can I pour concrete against pressure treated wood?

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.

Is it OK to leave wood in concrete?

Form wood left behind is nothing more than termite food and leaving it on the concrete is sloppy work and unacceptable. Make sure they take the wood with them and not leave it behind for you to deal with.

How long will pressure treated wood last in the ground?

40 years

What is the difference between #1 and #2 pressure treated wood?

Typically wood that is two or more inches thick is graded only for strength, denoted by #1, #2 and so on. And because stronger lumber has fewer and smaller knots, it’s typically more attractive. So the general rule of thumb for lumber grades is this: the lower the number, the more strength and better appearance.

How do you keep landscape timbers from rotting?

Another way to defend against rot is to try to form a protective barrier in between the treated wood and the soil. This can easily be accomplished by stapling a water-resistant tarp to the side of the wood wall that will be in contact with the soil.

How do you dry pressure treated wood without warping?

Experts recommend certain practices for drying wood to prevent warping, such as:

1. Don’t allow partially dry lumber to quickly regain moisture.
2. Don’t dry lumber too slowly (doing so could worsen any bowing and other warping)
3. Don’t over dry lumber, which can lead to cracking, splits and end grain checking.
