There are certain procedures that you must follow to ensure you fill the gap under your gravel board correctly. However, you can still use creativity in finding a solution. Every situation is different, so it is possible to make tweaks here and there to get the best results.

Most of the methods we suggested in this article involve some sort of filling. Here are the things you have to keep in mind when doing so:

  1. Decide on what filling you will use and if it is appropriate for your gravel board
  2. Prepare the needed materials
  3. Measure the gap and finalize how much material you will be needing
  4. Follow the filling instructions of your preferred filler to fill the gap

You must use blend seamlessly with the look of the gravel board. The filler must also be strong enough to protect the rest of the fence from moisture and insects that will lead to decay. 

Using the same gravel board material to fill up the gap is a great way to keep the aesthetics of your fence consistent. An opposite is a viable option as well. You can fill the gap with the same material as the ground your fence sits on.

For example, if the fence is on concrete, fill the gap with concrete. If it is on soil, then pack in some soil to close up the gap. However, filling the gap with soil might not be the best option if you have pets, especially dogs. Dogs can dig around the soil and uncover the gap you have covered.

Replacing The Gravel Board

If you deem it fit, you can also replace the gravel board. Removing the old uneven gravel board gives more access to the ground for leveling You can install better, stronger, and more even gravel boards that go into the ground seamlessly.

This option will of course turn out to be more expensive. Because of this, we do not recommend a complete overhaul of your fence's gravel board as much as possible. Unless, of course, it has serious damage.

Do Gravel Boards Touch The Ground?

Fences, especially wood fences, should not directly touch the ground. This is because the wood will absorb all the moisture and dirt coming from the soil or concrete underneath it. A gravel board sits right underneath your fence to remedy this.

Gravel boards touch the ground so your fence does not have to. They can be made out of treated wood or concrete. Some wooden boards are made out of composite, while others are reinforced with steel. 

A standard gravel board is between 4 inches to 6 inches tall, depending on the height of your fence. Since the gravel board touches the ground, you can keep out creatures or plants that could pass through gaps at the bottom. 

Gravel boards are a perfect way to protect your fences. They are made of strong enough material that can handle most of the elements that could otherwise damage your fence quickly. They can also add extra structural support as a foundation to your fence.

Normally, gravel boards are used to protect wooden fences. However, other materials like vinyl could benefit from a gravel board as well. Concrete and steel fences do not typically need or use gravel boards, as they do not rot the same way as wood does.

How Long Does Gravel Board Last?

Gravel boards are meant to last a long time. This can make installing them a little pricey since they are an additional cost to your already existing fence. However, since they do protect your fence, they can be a good investment and save you money for fence repairs in the future.

When installed right, your gravel board will last up to 8 years before needing any major repairs. Since a gravel board protects the fence, it will rot and be damaged before your fence does. 

The material of a gravel board might affect its longevity, but this is usually chalked up to the kind of environment it is in and what forces it is subjected to. Gaps in your gravel board could also be a result of damage over time, hence the need to fill them.

Though you can do away with a gravel board, having one adds an extra design element to your fence. That, and the fact that it protects your fence, as we have mentioned earlier.

Aligning Gravel Board With The Ground

You may notice that uneven ground can lead to stepping on your fences. This means that the fence boards are unaligned with each other because they are following the slope in the ground. 

Gravel boards are a great way to close the gap under uneven fence panels that have stepping. With a gravel board, your fence can give off the illusion that it is aligned. This provides a more streamlined and put-together look for your fence.
