If however, you are putting up a 4ft high fence, you will only need 6ft long posts. But heres the thing. Because not so many are used which means not so many are made which means they are scarcer. Which means they are more expensive — Crazy eh! This is easily overcome with the right tools and by hiring, or borrowing, a decent power disk cutter, an 8ft post can easily be trimmed down to the right size.
It is important that your powerful cutter is supplied with a dust suppression water bottle. The bottle is filled with water. The handle is pumped to build up pressure in the bottle and the hose is then connected to the cutter, the cutter started and the water turned on. A fine jet of water is then trained automatically onto the blade as it cuts through the concrete and the dust is kept to a minimum. The corner post, as you can see, accepts two panels, ar right-angles to each other, to form a corner in your run.
When you buy your posts they will be 2. You now have to work out how much to cut off the posts. Add to this the depth of the gravel board you want to use. In our exmaple pictured we are using nice strong concrete gravel boards at mm deep. Now add the height of the fence post that you would like to stick up above the fence panel. We have gone for a mm upstand. This is purely down to your preferance and many people like to have the panels flush with the top of the post.
Now add the depth of post which is to be concreted into the ground, in this case, mm. Add together the total height of teh fence panel, post and gravel board to work out how much to chop off of post. Adding the depth, to the gravel board, to the panel, to the upstand, gives us exactly 2m.
This means we had to cut mm off each post remember your measuerments might be different so you might be cutting off a different amount. Make sure you cut the mm from the right end of the post i. Be careful when using the cutter, they are very powerful indeed. If you decide to use an electric disk cutter you may find that each cut takes you an hour, and you wear out a disk for every post.
By using a inch petrol cutter with a diamond blade, it only takes about 20 seconds. Now dig your first hole. The depth, in this case is mm.
Look at our project on how to concrete fence posts using Postcrete and put your corner post in. Keep your level against the post, in both planes, until the Postcrete has gone hard.
A post level can be a useful tool to ensure that you are level in both planes:. Use a fence post level to ensure the post is level on all sides — Fence post levels available from our online store here.
To dig the postholes, we recommend you use a posthole digger or auger. When digging, make sure the holes are:. With a pound bag, you can make about 0. So, if your posthole is, say, 12 inches wide and 30 inches deep, it will require five bags of the mix.
To do so, follow these steps:. We mentioned above that installing multiple posts in a straight line can be challenging without the right techniques. If you want your posts to be perfectly aligned with one another, a string guide is an easy way to do this. To do this, you will only need some strong twine or string. If each post touches the strings, the result will be a fence that looks very straight and professional.
If you live in a region with lots of rainfall, rather than topping off each hole with soil, you instead could top it off with more concrete, which will divert water away from your post.

Guide to Installing Concrete Fence Posts. A measuring wheel: Without a doubt, using a measuring wheel is the best way to measure for a fence. A measuring wheel shows highly accurate measurements on an easy-to-read counter.
Most fencing pros use these, and while some models can be quite expensive, the precise measurements they provide make them worth the price. A tape measure: If your budget is limited, you can use an old-fashioned tape measure instead of a measuring wheel, but if you choose to measure this way, we recommend you do this with one other person so they can keep track of the ground that you have measured.
Garden stakes are the best markers, although spray paint is another great option. Fencing professionals traditionally have used orange spray paint, but you are, of course, welcome to use any color of spray paint you like.
Make sure the post you choose is labeled as suitable for ground contact! Since wood posts may rot over time, apply a non-water-based, brush-on wood preservative like copper naphthenate first. If your soil is dense, you can dig the hole, add gravel, and brace the post with lumber. If it's not, you'll need to set the post with concrete, which is a slightly more labor-intensive process.

You can install your posts directly into the soil as long as it's dense and has good drainage.
The installation is more labor-intensive and a bit less stable than concrete, but also cheaper and often more decay-resistant. Due to additional strain, gate posts work better when installed in concrete. Choose a durable fence post. Follow local advice if possible, since climate and availability will affect this decision.
Unless you live in a desert, it pays to choose durable lumber, which comes in two varieties: Posts made entirely from durable heartwood. Western juniper, black locust, and Osage-orange are excellent choices. Aspen, ponderosa pine, lodgepole pine, and Douglas fir are suitable examples.
Buy this from a trusted source to avoid poorly treated wood. Note — All lumber should be labeled as suitable for ground contact. Not all pressure-treated wood is intended for burial. Prep the wood against moisture optional. The sawn-off ends of the fence post are vulnerable to moisture. Wood preservatives are toxic, so follow safety recommendations on the label. Apply multiple coats of the copper naphthenate and make sure to let it dry for 24 hours after each application.
Dig the hole. As a general rule, an 8 foot post needs to be placed so that two feet of it are in the ground. If you plan to anchor the post in soil, the hole diameter should be as close to the fence post size as possible. If you plan to anchor the post in gravel, dig a bit wider — roughly 8 inches 20cm across for a standard 4x4 post. Use a post hole digger to dig a straight-walled hole. Keep some dirt or dirt mixed with gravel nearby to backfill the hole.
Drop gravel into the hole. A couple inches few centimeters of pea gravel or crushed stone improves soil drainage. Tamp it down well. This is especially important if your soil has poor drainage. You can use a wooden stick or broken wood tool handle as a tamping bar, or a piece of scrap lumber. Position the post in the hole.
Center the post in the hole, and get it level and in line with the other posts. An assistant will be useful to hold this in place during installation. However, if you are going to yourself have some 1"x 4"x 4' or longer material available. Make sure that you measure the distance between your posts to ensure that the top and bottom rails will fit. Fill the hole with tamped crushed stone or soil. Crushed stone offers better drainage than soil, and may improve stability as well if well tamped and installed in dense soil.
Whether using crushed stone or ordinary soil, shovel it in 3—5 inches 7. Before each tamping, hold a level against the post and adjust until level. If you'd like to plant grass at the base of the post, use soil for the last couple inches several cm , not gravel. Finish with a small hillock. Build up the soil at the base of the pole to make a small "hill" sloping away from the post in all directions.
The spot where the post leaves the ground is the most common location for rot. Good drainage here is extremely important. Method 2. Set posts in concrete when stability is extra important. Concrete may be necessary if you are installing a fence in sandy soil, or in very soft, muddy soil. It's also a good idea when installing gate posts to provide extra stability. The main downside to concrete is its ability to trap water around the post.
This can reduce the lifespan of the post by many years. The installation described here avoids this problem with a gravel base and an open-bottomed concrete sleeve.
