building a new wooden natural fence - work tools

Q:The last time I installed the fence, it didn’t last long because I had underestimated the amount of concrete needed for the job. I want to get it right this time around, so how much concrete is needed for each fence post to secure and support the fence?

A:Finding the right amount of concrete depends on the size of the hole and the size of the pillar. The diameter of the hole should be about three times the diameter of the cylinder and the depth of the hole should be about ⅓ to ½ of the total post length. With these measurements it is possible to determine the volume of the cylindrical hole and the volume of the cylinder inside the hole.

To determine the amount of concrete needed for each fence post, simply subtract the post volume from the hole volume of the hole to find the mass of concrete. Just be aware that the pillar hole should be deeper than the frost line and you should also have about 6 inches of gravel at the bottom of the hole for good drainage and frost protection.

Consider the size of the hole and the depth of the post in the ground.

To calculate the exact amount of concrete needed for each pillar, you must determine the diameter and depth of the hole as well as the diameter and height of the pillar. The cylinder hole diameter should be 3 times larger than the cylinder diameter, so a 4 inch diameter cylinder will have a 12 inch diameter hole.

The depth of the hole should be approximately ⅓ to ½ the height of the post. For example, a post 6 feet long will require a hole at least 2-3 feet deep, although the gravel layer and icy track should also be taken into account when determining the depth of the hole.

Don’t forget the icy road in your area.

As noted above, icy lines can be an issue affecting the required hole depth. The ice line refers to the specific depth at which the ground freezes completely during the coldest months of the year. Depending on where you live, the icy track can range from non-existent to 10 feet deep, so it’s important to check the average depth of the icy track at your particular location before attempting to build a fence.

The average icy track for most areas is around 3 feet down, so a suitable minimum depth would be around 4 feet. In colder locations, the post hole may need to be dug much deeper. This means that if the icy track is typically 6 feet deep in your area, the fence post hole should be about 7 feet deep, even if the fence is only 4 or 5 feet deeper. above ground.

Remember the item in a layer of gravel.

Gravel is an important factor to keep in mind when installing a fence. A layer 6 inches thick should be poured at the bottom of each hole to act as a barrier between the wooden posts and wet dirt, making the posts less susceptible to frost. The gravel layer also helps drain water away from the base of the pillar, reducing the risk of wood rot.

This 6-inch layer of gravel cannot be ignored when determining how much concrete is needed to fill the hole. While the hole may be 42 inches deep, you must subtract the gravel layer from 6 inches to calculate the correct amount of concrete. So the 42 inch hole is basically a 36 inch hole for the purpose of determining the amount of concrete.

Calculate the amount of concrete per pillar.

To find a specific amount of concrete, you will need to calculate the volume of the cylinder inside the hole and the volume of the cylinder hole using the following formula:

Rectangular post / hole: volume = length x width x depth
Example: 2 x 2 x 36 = 144 cubic inches

Cylindrical cylinder / hole: volume = radius² x π x depth (π = 3.14)
Example: 1.5² x 3.14 x 36 = 254.34 cubic inches

Remember that to find the radius, simply divide the diameter by 2. After finding the volume of the cylinder and the back hole, simply subtract the volume of the back hole from the volume of the hole to find the total volume of concrete needed to fill the hole. hole.

Quantity of concrete: volume = loss volume – post volume
Example: 5184 – 144 = 5.040 cubic inches

Convert the total volume to cubic feet or cubic feet if necessary. A cubic foot is equal to 1728 cubic inches.

Convert to Cubic Feet: volume of concrete in cubic feet = volume of concrete in cubic inches / 1728
Example: 4823.04 / 1728 = 2.79 cubic feet

By following each step, you can find the exact amount of concrete needed for each post.

Complete the calculation:Example: An 8 foot high round post with a 4 inch diameter should have a hole in a 4 foot post with a 12 inch diameter. Only half of the cylinder will be in the hole, so the post volume should be based on a post that is 4 feet by 4 inches in diameter.

  1. Find the radius of the column: radius = radius / 2
  2. 4/2 = 2 inches
  3. Find the volume of the puzzle: volume = radius² x π x depth
  4. 2² x 3.14 x 48 = 602.88 cubic inches
  5. Find the display hole radius: radius = diameter / 2
  6. 12/2 = 6 inches
  7. Find the volume of the hole: radius² x π x depth
  8. 6² x 3.14 x 48 = 5425.92 cubic inches
  9. Find the volume of concrete: mass = volume of the hole – mass of the column
  10. 5425.92 – 602.88 = 4823.04 cubic inches
  11. Convert to cubic feet: volume of concrete in cubic feet = volume of concrete in cubic inches / 1728
  12. 4823.04/1728 = 2.79 cubic feet

For reference, a 40 pound bag of concrete typically produces about 0.3 cubic feet, a 50 pound bag for 0.37 cubic feet, a 60 pound bag for 0.45 cubic feet, and an 80 pound bag for 0 .6 feet. This means that in the example above, each post would claim approximately eight 50-pound bags.

Alternatives to concrete for installing fence posts.

Digging and backfilling a fence post with concrete can be a long and arduous process and may require at least some math to determine the correct amount of concrete needed for each post, but concrete is only one method. . Do-it-yourselfers who are not interested in using concrete have several alternatives including:

  • Backfill the pit with compacted gravel by digging a hole the size needed for the concrete, then adding about 5 inches of gravel at a time, compacting often to ensure the gravel has very little room to move and teleport.
  • Expanded fill composites such as
  • 2K fast
  • can be used in place of concrete to fence in minutes and at a lower cost.
  • For fence post repairs, consider using ground fence anchors, such as
  • Anchor ATV Fence
  • to repair a cracked or damaged fence post instead of digging up the concrete foundation and replacing the entire post.

First we had to dig the fence post holes. To do that we used a one-man post hole auger.

-https://youtu.be/xbYsQ_IdRdE

We were setting fence posts in concrete. This is a typical way to install a fence but not the only way. The fence post cement we used was Quikrete post cement. It sets up in 20-40 minutes and is strong enough for fence installation after curing for 4 hours.

To begin, we strung a line from one corner fence post or stake to another corner fence post or stake. That provided a straight measuring line with which to align all the middle fence posts. Our fence post spacing was typically 8 feet from post to post. The fence post hole depth was 30 inches of more with 4-6 inches of gravel at the bottom of the holes.

How much concrete per fence post varied from hole to hole. It averaged 1-2 50 pound bags.

To measure how much concrete for a post hole, you need use the width and the depth of the hole less the volume of the actual post. Use the formula for the volume of a cylinder.

That is about it! You should have a good idea how to put in a fence post. So go do it!
