Let’s assume you’re installing a 6-foot high fence, where 2 feet of the post will be in the ground, and you will need twenty (20) 4″ nominal round posts. Let’s use an example to illustrate what we covered above. If you have multiple different size post holes to fill, calculate each set with matching dimensions separately, then add the totals together. Don’t forget to add in some extra for spillage and waste. Simply multiply that amount times the number of posts to get a total quantity.

With the volume of the submerged post and the volume of the hole figured out, subtract the post volume from the hole volume, and you will have the volume of concrete needed for each hole. Volume = radius 2 × π × depth (π = 3.14) Calculate Concrete Volume Use these formulas to calculate volume or, for round holes, use our cylinder cubic yardage calculator. Use our calculators to quickly convert inches, yards, or meters to feet. To easily use the table above, convert your units to feet if they aren’t already. Then calculate the volume for the part of the post that will be submerged in the hole. Your post diameter and height determine how big each hole needs to be.Īs stated above, fence post holes should be three times the diameter of your post and 1⁄ 3 as deep as your post.įirst, you need to calculate the volume for the post hole. To calculate how much concrete you need, you need to know the post size you are going to use and how many posts you are installing. How Much Concrete Do You Need Per Fence Post?Ĭoncrete is sold pre-made (and usually delivered) by the cubic yard or in pre-mixed bags by weight. Expired epoxy may not be suitable for use because it may not harden.Illustration showing a post hole with a diameter that is three times the post’s diameter and with a depth that is 1/3 the height of the post. Don't Use Expired EpoxyĪlways check the expiration date on the epoxy you are using before putting it in the anchor bolt holes. If the temperature is below 40-degrees Fahrenheit, the mixture may need to harden a lot longer. It may take 5 to 7-minutes before the epoxy mixture hardens depending on the temperature. Check the manufacturer’s recommended schedule for curing their specific products. Do not make haste because the epoxy needs to cure first in order to provide maximum strength.

Don't Install the Hardware Until the Epoxy is CuredĪllow the epoxy to fully cure before installing a load or anchoring any object with the fastener. However, it is necessary to fill the hole completely when the hole is submerged in water.

Fill the hole from ½ to 2/3 of the depth only.

Don't Fill the Anchor Hole with Epoxyĭo not fill the entire hole because the anchor will occupy the space afterward. Usually, epoxy is recommended to be stored at temperatures ranging from 40-degrees Fahrenheit or higher. When storing epoxy, follow the recommended temperatures in order to avoid damage.

Blow the hole once again to ensure that it is free from dust. Afterward, insert a brush inside the hole to dislodge other debris that may have been left inside. Use a blower or a vacuum to remove the dust inside the holes. Do Clean the Holes Before Applying Epoxyīefore filling the hole with epoxy, make sure that the hole is clean and free from dust and any other debris. Clean the hole out thoroughly before inserting the anchor bolt or other fasteners. The optimum bit diameter is 1/16th of an inch bigger than the fastener. Remember that drilling the holes correctly plays a very important factor not only in the installation of the anchor but also in the application of concrete anchor epoxy. The drill bit should not be too large for the anchor and not too small to restrain anchor entry. When preparing the holes for the anchor, make sure to use the right sized drill bit.
