How Deep Should A Fence Post Be?

How Deep Posts

When people think about how to best secure a fence, they might think about using concrete bases. Here at Northland Fence, however, we prefer to drive our fence posts during the installation process instead of using concrete. Our 15+ years of experience in the field and our constant desire to deliver the highest quality fencing possible has led us to choose driving over concrete.

We drive our fence posts at least 4 feet into the ground. When you drive a fence post that deep, you don’t have to worry about the potential for heaving, cracking, or erosion compromising the integrity and structure of your fence. This also provides a cleaner installation process, not leaving any messy spots from digging for concrete, nor is there any waiting time for drying after the fence is finished being installed.

We want only the best for our customers. We believe in treating them and our employees like family, which means not short-changing them on quality when we install our fences. Learn more below about the different ways to secure your fence and how driving works in the long run.

Is It Required to Add Mixing to Keep a Fence Post Sturdy?

The way your fence post is installed directly impacts the life of your fence as well as what you might need to do to maintain it over time. If you don’t drive your fence post into the ground, many people will instead opt for concrete in order to create a sense of stability.

If your fence post isn’t driven into the ground, you will need something else to support it so it won’t easily fall over and it will be able to support the weight of the fence around it. Many people might opt for concrete because it’s more readily available to them or it’s the only method they’ve heard of before.

Here at Northland Fence, our years of experience have led us to see the benefits of driven posts versus concrete in the long-run for our customers. Driven posts provide the best strength and lifespan with the least maintenance. If you have driven fence posts, you don’t need to add anything to them in order for your fence to stay strong and secure. Most homeowners and small fence installers don’t use this method because the machinery to drive fence posts costs over $1,000 for a decent driver. That doesn’t make sense for a homeowner using the tool only once or the smaller contractor without a budget. At Northland Fence, we install thousands of fences a year, so we our able to purchase the highest-grade tools to help our customers get the best possible fence.

How Many Bags of Cement Are Required per Fence Post?

There are many variables that come into play when you decide to use concrete in the support system for your fence posts. The post size and depth all impact how much concrete you need in order for it to maintain good integrity. These numbers can vary anywhere from 1 bag per post to 11 bags per post.

This can add up quickly and still have the potential to fail due to erosion, inclement weather conditions, or even man-made accidents such as a car hitting it.  In addition, there is a lot of additional work that comes with installing a post using concrete. With concrete, you have to dig up a much larger area to make room for the installation. Then there is the drying time to consider where you have to be potentially delicate around your fence posts until it’s fully cured.

With driven posts, once it’s in the ground, it’s totally secure. There’s no additional wait or messy dirt to worry about afterward. This is just one of the many reasons we at Northland Fence choose to drive our posts when installing your fence.

Does the Height of the Fence Determine How Deep a Fence Post Should Be Buried?

In order for fences to be nice and secure, they have to be driven into the ground an amount that depends on the fence itself. It’s generally recommended that at least 50% of the length of what’s shown above ground is buried below ground. This means if you have a 6-foot tall fence, there would be 3 feet buried underground.

However, putting the post deeper into the ground than the above suggestion will not hurt the fence. In fact, it will make the fence a little more secure. The deeper it is underground, the less you have to be concerned about potential issues of erosion affecting your fence.

Overall, there are many pros to driving your fence posts into the ground versus using the traditional method of concrete bases. With driven posts you get:

  • Extreme durability
  • Posts that are guaranteed not to heave
  • Safety from water-related damage
  • Cleaner installation process
  • Superior strength compared to cement posts
