Question: How To Cement Fence Posts

Should fence posts be set in concrete?

Setting Fence Posts in Concrete Concrete is the most secure material for setting fence posts, especially if you have sandy soil. Gravel may be okay with dense, clay-heavy soil, but in looser soil, concrete is the only thing that will truly keep your fence posts stuck in place.

How many bags of cement do I need for a fence post?

1 – 4 bags of concrete per fence post are typically what’s needed. This depends on the type of soil, fence design, height, post size and bag weight. In general the depth of the post’s hole needs to be 1/3 to 1/2 of the above ground height of the post.

What is the best concrete mix for fence posts?

For a small to mid sized job I recommend going with premixed. The best concrete mix for fence posts I’ve found is Quikrete Fast Setting Concrete Mix in a 50 lb bag. It’s 4000 psi, easy to work with, sets up fast, and doesn’t need to be mixed. Just pour it in the hole and soak with water.

Can you set fence posts with dry concrete?

Like a good wine, a dry setting concrete will take time to set fully. A quick setting product may not be the best one, and the standard setting time is around four hours. Make sure the post is plumb at all times during the process. Do not attach any weight or do any work on the post while the concrete is drying.

Is 2 feet deep enough for fence posts?

2 feet is the minimum depth that you should dig your fence post holes for. To dig the holes one-third to one-half of the post’s aboveground height, is a general formula. The deeper you dig the holes, the more stability your fence has.

Can you reuse fence posts with concrete?

Pulling up an existing fence post to reuse can be quite a task. Posts with concrete at the base are the most difficult to remove and reuse because the concrete base is larger than the post, which makes pulling it up through the ground much harder.

Is it better to nail or screw fence boards?

Nails are faster than screws to install, meaning less labor for you or your builder (which may translate into lower installation cost). Screws, on the other hand, secure the fence better than nails. They also ensure easier rework should you need to replace a damaged picket.

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.

What is the easiest way to dig post holes?

You can use a post hole digger or power auger to dig the hole. A post hole digger is a manual tool and will get the job done in average soil. If you have hard, rocky soil or a lot of roots – you may want to opt for a power auger. Many home improvement stores have them available for rent.

How much Postcrete do you need per post?

The exact amount of Post Mix Concrete needed will vary depending on the width and depth of the hole, but as a general rule you’ll need about one and a third bags for a standard fence post.

Can I pour concrete in a hole full of water?

The water in the hole under the pipe can be sucked out with a wet-dry vacuum before and during the repair job.

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 far apart do you put fence posts?

Most fence posts can be spaced 8 to 12 feet apart. While this is a general criteria, it doesn’t cover all scenarios. For instance, high tensile fence can have larger spacing, requiring line posts every 15 to 20 feet for field fence styles, and as much as 20-30 feet for high tensile barbed and smooth wire.

How tall should a fence be for a 6-foot fence?

As a general rule of thumb, you’ll need to place at least 1/3 the height of the post in the ground. For example, a 6-foot tall fence will need at least 2 feet of post in the ground.

Why do posts need to be below the frost line?

Dig holes Posts need to be set below the frost line to prevent heaving. For regular privacy fences, holes need to be at least 36 inches deep or half the fence height, whichever is greater, plus six inches for base gravel. Lower fences will not likely need to be as deep (or you may use ground spikes instead).
