Sets posts without mixing. Subsequently, question is, how much concrete do I need for fence posts? Also remember, the depth of the post hole should be one-half of the above-ground post height. Example: For a 6' above ground post , use a post with an overall height of 9 feet and place 3 feet in the ground.
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. The ideal solution is to eliminate contact between soil and wood.
Using a metal post anchor set in concrete is probably the most effective method for achieving maximum longevity. To help keep the post from wicking water, choose an anchor that spaces the post bottom away from the concrete.

Whether you are building a fence or setting a single post , adding curb appeal with a mailbox or setting a basketball goal, the best way to guarantee your post will be sturdy is to set the post in concrete. Is 2 feet deep enough for fence posts? The minimum depth that you should dig your fence post holes for panel sections is 2 feet. A general formula is to dig the holes one-third to one-half of the post's aboveground height. Concrete is strong enough on its own to support the post but not resist the weight of the fence section.
No matter what concrete mix you end up using, the most important thing is that you build a strong base for your fence post. Make sure the hole is wide enough and deep enough for the type and size fence post your installing. The fence is only as strong as the posts that support it. Weak posts will cause your fence to shift and possibly fall down. This is one of the main reasons I prefer using concrete over a synthetic foam. Concrete is very heavy. Make sure to use a strong post too.
A weak post will fail overtime. If your fence post is a bolt down then make sure to use strong, good quality bolts and drill them deep. The post will only be as strong as the bolts. In cases like this your concrete is just an anchor, the metal base is what holds up the post and supports the fence.
Make sure the concrete footing has a flat bottom and is straight down, not on an angle. If the bottom of your footing has a point it can start to drill itself down into the earth and sink.

This may sound like a pretty simple job but there is a fair bit more to it than just this, esepcially if you want your fence posts and ultimately your fence to last more than just a few years. You will need to adjust your measurements accordingly depending on the size of posts or panels you are using.
A common question we hear is; How do I keep my fence posts from rotting? To ensure as long a life as possible, all posts should be pressure treated timber to avoid rot and wood boring insects.
You should also try to avoid fence posts made using sapwood the lighter outer part of the tree. If you can use posts made from heart wood the darker wood at the centre of the tree.
Accuratly measuring and marking where your posts are going to go is key to the success of your fencing job as a whole. The exact spacings will be determined by the length of the fence panel or type of fence your going for. First, measure the length of one of your fence panels as this will tell us how far apart our posts need to be. In most cases, this will be around 1. Starting at one corner or the beginning of your fence run, hammer in a stake to mark the location of the first post.
Make sure the stake is hammered in at the centre point of where your post will be. Next measure out from the centre point of the stake, the length of your fence panel or other chosen length to the location of the next post and add a further 4 inches or mm. As we are measuring effectively from post centre to post centre we need to account for the further 2 inches of post based on 4 inch posts. Tie a piece of string around one of your corner posts and run it all the way along to the corner post at the other end.
Pull it tight and tie it off. Look down the string line from one corner post to the other and the string should be in a direct line with all the stakes in between running along the line. Stakes are knocked into the ground to mark the locations of each fence post and then string is tied to first and last post to keep all posts inline. The next job is to dig out all of our fence post holes, but first we need to know how big they need to be.
A 6 foot high fence should have an 8 foot post with at least 2 feet in the ground, a 5 foot fence should have a 6 foot 6 inch post with 1 foot 6 inches in the ground etc.
Gravel provides a solid base for the fence post to sit on and prevents it from coming into direct contact with the soil below, which might increase the risk of rotting. Tamp down the gravel using the bottom of the fence post. To do this, set the post in the hole and, with gloved hands, lift the post up a few inches and bring it back down hard on the gravel. Repeat this three to five times to even out the gravel. Position the post in the center of the hole and hold it upright. Then, pour dry Quikrete Fast-Setting Concrete Mix into the hole, getting an even amount around all sides of the post.
Continue filling the hole with the dry fast-setting concrete mix until the mix sits approximately three inches below ground level.
A pound bag of mix will make approximately 0.
