Step-by-Step Processes for How to Fill Gap Under Fence With Dirt

Step 1: Inspect the Fence

Before beginning the process, carefully examine the fence and the gap beneath it. Ensure the posts and panels are secure and not in danger of shifting or falling over. It is also important to identify if there are any low spots or dips in the existing ground beneath where you will be placing dirt.

Step 2: Remove Weeds and Debris

After you have inspected the fence, remove any weeds or debris from beneath it. Be sure to dig down and rake away any large rocks or roots that may be in the way. Use a garden shovel or metal rake for this task. Using a long straightedge, check the contours of the existing ground beneath the fence.

If there are any low spots or dips in the ground, you will need to fill them in before adding new dirt.

Step 3: Grade and Level Ground

Once you have identified any low spots or dips in the existing ground beneath the fence, use a garden rake to grade and level the ground. Add soil as needed until you have achieved an even, flat surface. For added fertility and drainage, spread a thin layer of compost or manure over the area before adding new dirt.

This will help ensure that your plants get the nutrients they need to grow and flourish.

Step 4: Add Topsoil

Use a shovel or garden rake to spread an even layer of topsoil over the area beneath the fence. Remember that you will be adding more soil later, so make sure not to fill it too high at this stage. Once the topsoil has been added, use a garden rake to level it and ensure it is even. If there are any low spots or dips, add extra soil as needed to bring the area up to grade.

Step 5: Install Edging

Install Edging Material

If desired, you can install edging material around the perimeter of the area beneath the fence. This will help keep the soil in place and add a finished look to your project. Once the topsoil has been added, spread a thin layer of mulch or rock over the area. This will help to keep moisture in, suppress weed growth, and add a decorative touch to the landscape.

Step 6: Plant Plants or Seeds

Now that you have filled the gap beneath your fence with dirt, it is time to add plants or seeds. Choose plants that are suited for the amount of sun and shade in the area beneath your fence. Once you have chosen the plants or seeds, plant them according to the manufacturer’s instructions.

How Do You Prevent Weeds and Pests From Entering the Gap After It is Filled With Dirt? 

Filled the Gap Under Your Fence

Once you have filled the gap under your fence with dirt, it is important to take preventative measures to ensure that weeds and pests do not enter the area. To prevent weed growth, layer a sheet of plastic playground mulch over the dirt and secure it in place. This will block the light needed for weed growth while allowing water and air to pass through.

To deter pests, apply an insecticide or pesticide to the plastic mulch to stop insects and other pests from crossing into the filled gap.

Additionally, you can use a physical barrier such as wire mesh or netting to add another layer of protection against unwanted visitors. Finally, it is important to regularly inspect your fence for any signs of damage or gaps and to fill them promptly with dirt. Doing so will help keep your fence secure and free from weeds and pests. 

By taking these steps, you can ensure that the gap under your fence is filled with dirt to prevent further issues. 

How Often Should You Check the Level of the Dirt to Ensure It Remains Even? 

Once the dirt has been filled in to fill the gap, it is important to check it periodically to ensure that the level of the dirt remains even. How often you should check depends on several factors, including weather conditions and how often your fence is used. Generally, you should inspect your fence at least once every few months.

Pay particular attention to spots where the dirt may have been disturbed, such as near gates or animal enclosures. It’s a good idea to check more often during periods of heavy rain and snow, since these weather events can cause the soil level to shift.

If you notice that the dirt has become uneven, take the time to adjust it. You can do this by adding more soil where it is needed or removing excess soil where necessary. If the gap is large enough, you may need to use a rake and shovel to help level out the dirt before filling in any gaps.

Once you have filled in the gap, remember to check its level periodically and make adjustments if needed. Doing so will help ensure that your fence remains strong and secure for years to come. With a little bit of maintenance, you can keep the gap beneath your fence filled with dirt and looking great all year round.

How Can You Avoid Creating Air Pockets When Filling the Gap With Dirt? 

Create Rot in Your Fence Posts

When filling the gap under a fence with dirt, it is important to avoid creating air pockets. Air pockets can cause water to become trapped and, over time, create rot in your fence posts or other structure. To help keep air pockets from forming, take the following steps:

  • Begin by sprinkling a thin layer of soil over your filling area.
  • Next, use a tamping tool or your hands to press and compact the soil into place. This will allow any air pockets to be worked out of the dirt and compressed against each other.
  • Fill in any remaining gaps with dirt and repeat the process until all gaps are filled.
  • Finish off the area by using a rake to spread an even layer of soil over the top. This will help create a stable surface and reduce the risk of air pockets forming between dirt particles.

By following these steps, you can successfully fill any gap under your fence with dirt and avoid creating air pockets. Doing so will help extend the life of your fence and other structures.

How Can You Prevent Waterlogging of the Soil in the Gap?  

When filling the gap under your fence with dirt, it is important to make sure that you take some steps to prevent waterlogging. Adding a layer of gravel beneath the soil can help keep excess moisture away from the area and allow proper drainage.

Adding a Layer of Gravel

Additionally, ensuring that there is a slight slope in the ground leading away from the fence towards an area where the water can naturally drain away is important. Lastly, adding some kind of fabric or tarp beneath the soil is also a good idea to help stop any water from pooling in the area.

These steps will ensure that your fence is not susceptible to rot and other damage caused by waterlogging. Another important consideration is to be sure to use soil that is not too sandy or overly moist.

If the soil you fill your gap with contains too much clay or moisture, it can create a heavy and wet pack that will cause issues for your fence and the surrounding area over time. The ideal type of soil for filling gaps under fences should be light and with good drainage capabilities.

How Long Does It Take to Fill a Gap Under a Fence With Dirt?  

Filling a gap under a fence with dirt can typically take anywhere from several minutes to several hours, depending on the size of the gap. For small gaps, you can easily fill them with pre-made bags of topsoil or potting soil. If you have larger gaps, you must bring in more soil or other fillers.

It is also important to use the right type of soil to fill gaps, as some types can erode quickly and may not stay in place when it rains. If you are using dirt from your yard or from a nearby area, you will need to loosen it up and make sure there are no rocks or large chunks that could create air pockets or weaken the soil’s stability.

Ensure That Your Fence Does Not Move

Once you have the right amount of soil, it is a good idea to tamp down the area to ensure your fence is secure. This will help ensure that your fence does not move when there are large amounts of rain or wind.

You may need to add soil or gravel to fill in the gaps if necessary. You can also use geotextile fabric or landscape fabric to help stabilize the area and prevent erosion.


The primary disadvantage of using dirt to fill the gap under a fence is that it does not provide much stability. Dirt can easily be shifted or washed away, which could cause the fence to become unstable and potentially even collapse. Additionally, there is potential for rodents and other pests to burrow into the dirt, causing further problems with pest infestation.

In conclusion,  filling the gap under your fence with dirt is a simple but effective way to ensure that animals and other pests do not get into your yard. You can have an even more secure and attractive fence line with just a few simple steps. First, measure the size of the gap. Next, clear away any debris or weeds from the area.

After this, fill the gap with soil and then press down firmly to create a sturdy foundation. Finally, add mulch or other decorative materials on top to finish the project. I hope reading this post has helped you learn how to fill gap under fence with dirt. Make sure the safety precautions are carried out in the order listed.
