How much concrete do I need for fence posts?
Most fence post holes will need between 1 – 4 bags of concrete to securely hold the post in place. The best way to determine the size of the hole is: Diameter of the hole is 3 times the width of the fence post. Depth of the hole is one-third to half the above ground height of the fence post.
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.
How much concrete do you need for a 4×4 post?
Mix two 50lb bags of concrete with water in a mixing tub or 5-gallon bucket. Add concrete into the hole and around the 4” x 4”. Depending on your climate, let concrete set up for 24 – 48 hours.
Should you fill fence posts with 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.
What is the best concrete mix for fence posts?
In terms of the ratio to use for a concreting fence posts, the best mix is a mix of 1:2:4 (1 cement, 2 sand, 4 aggregate).

How do you keep fence posts from rotting in concrete?
Fill the first three inches up with gravel so the end of the post doesn’t come into contact with the dirt. Gravel allows water to drain quickly away from the post and into the soil. Be sure to place the post in the center of the hole. Finally, fill the entire hole up with cement to the top.
Will wooden posts rot 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. The concrete at the top should be sloped away from the post to grade level to avoid water pooling around the base.
Is 2 feet deep enough for a 6 foot fence?
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 build a fence without a sinking post?
If you need a temporary fence or a border that you can move as needed, a quick way is to use concrete blocks. Attach a bracket to a concrete block that is heavy enough to hold the wood or other material you plan to use to build the fence. The posts can be mounted to the brackets and the fence finished from there.
What size Post do you use for a 6 foot fence?
The depth of the post hole needs to be 1/3 to 1/2 the height of your fence. For example, if you are building a fence that’s 6 feet tall, you will need a hole that is at least 2 feet deep. That also means that you’d need to use an 8-foot 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 much area can one bag of cement cover?
One 50-pound bag of Quikrete Fast Setting Concrete Mix yields about. 375 cubic feet. For example, if you need to cover 33.333 cubic feet, using 60-pound bags of concrete, divide 33.333 cubic feet by. 45 cubic feet to get 74.07 total bags of concrete.
Why do farmers put rocks on fence posts?
These fence posts served several purposes. First it obviously anchored a fence so that you could tighten the wires that ran for miles to keep the cattle in. Second, it was a place to pile the rocks strewn over the prairie. It just feels good when driving into the Osage and seeing those rock piles along the roads.
How long will a treated 4×4 post last in the ground?
A treated 4×4 will last 20 to 25 years in the ground if the conditions in the soil and climate are favorable. That number could increase to 40 to 75 years if you install the treated 4×4 in a cement ring rather than the soil. There are a few factors that influence how long the 4×4 can last in the ground.
How long will wooden posts last in concrete?
A pressure treated post will last around 10 years. if you use metposts the post will still rot they just make it easier to replace & in my opinion they look horrible. In my experience metposts are less secure than concrete too.
