Tips For Installing Wooden Fence Posts In Very Sandy Soil

Posted on: 14 March 2017

If you are tired of your neighbors looking into your backyard all the time, then installing a wooden privacy fence is a great idea. However, if you have never installed fence posts in the sandy soil in your area, then you are likely concerned about the future structural integrity of your fence. Thankfully, there are many things you can do to ensure that the fence posts will be securely set into the ground, even in the sandiest of soils.

Since your privacy fence is an investment and you want to keep it standing tall for years to come, follow these fence post installation tips:

Tip: Dig a Very Wide and Deep Hole for Each Fence Post

When you want to secure fence posts in shifting soils, you must dig deeper and wider holes than you would need to do so if the soil had more clay in it. For each post, you need to dig at least a couple of feet in depth and width. This added space is necessary to allow space for extra gravel and cement. If you are having problems with the sand filling in the hole as you dig, simply wet it with your hose and this will make the job a lot easier.

Tip: Use Gravel and a Level to Install the Fence Post in the Hole

Once you have dug your fence post hole, then you should place the post into the hole and surround it with gravel. You should use a small gravel for this project, and you must tamp it down in place so that it will hold the fence post in place. 

Using a contractor's level, move the post gently around in the gravel to ensure that it is level and plumb. 

Tip: Moisten the Fence Post and Its Hole Before Inserting the Cement

Before you put cement into the post hole, first you must wet the lower portion of the fence post, the gravel base material, and the sandy sides of the hole itself. The moisture is necessary to properly cure the cement into concrete. 

Tip: Fill the Post Hole so the Cement is a Few Inches Below the Grade

Finally, since you do not want concrete visible in your post holes, you should fill the post hole so the cement is a few inches below the top of the soil. Once the cement has cured, then you can cover it with a layer of soil to hide the anchoring concrete. For more information, talk to a professional like Askatu Construction.
