  1. Decide on what filling you will use and if it is appropriate for your gravel board

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.

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.

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.
