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 deep should an 8 foot post be in the ground?
In general, holes should be at least 3 feet deep for posts that extend 8 feet or more above ground level. Posts that extend 6 feet above ground level should have holes at least 2 1/2 feet deep.
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 deep into the ground should a fence post go?
The width of the post hole should be 3 times the width of diameter of the post. For example, if you are erecting a 6 foot high fence using 4 inch fence posts, the posts need to be 6 feet above the ground. 6 divided by 3 is 2, therefore the depth of the hole required is 2 feet.
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.
How many bags of concrete do I need for a fence post?
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.
How big of a hole do you need for a 4×4 post?
The diameter of your post hole should be three times the diameter of your post. So, if you’re planning on using a four-inch round or 4×4-inch square post, your post hole will need to be 12 inches in diameter. For a six-foot-high fence post, we would need a hole that’s 36 inches deep and 12 inches in diameter.
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.
What is the maximum distance between 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.
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 do you protect a wooden post from rotting in the ground?
How to Protect Wooden Fence Posts From Rotting
- Set the wooden fence posts in a cool, dry area with plenty of air circulation so the wood can dry.
- Brush the bottom third or bottom half of the fence post with waterborne copper naphthenate, a wood preservative that is free of arsenic and chromium.
How much Postcrete do you need per post?
You’ll need to bury the posts at least 2ft In the ground. As for how many bags of postcrete you need per post, that’s purely dependant on how big you make the post holes. As a rule of thumb, when using standard post hole diggers, I average 1 bag per post. For larger holes I would allow 1.5 bags to 2 bags per hole.
