What Are Gravel Boards?

First, let’s make sure we know what a gravel board is. A gravel board is a flat piece of wood that goes at the bottom of a fence panel.

Basic Features: Gravel boards are put between the fence panel and the ground. Most standard gravel boards are the same height, with heights between 140 mm and 150 mm being the most frequent.
Core Function: The most fundamental and crucial purpose of a gravel board is to separate the major part of the fence panel from the ground. This wall stops the fence panel from reaching the ground, which is damp, has mulch, grass clippings, rocks, and all sorts of pests on it.

Do Composite Fences Really Need Gravel Boards?

It is not necessarily necessary to put gravel boards on composite fences, to be honest. One of the best things about composite materials is that they can handle the weather better than ordinary wood. They are constructed of a blend of old plastic and wood fibers. They don’t rot, insects don’t hurt them, and they don’t break because of this particular blend.

If you want to safeguard your investment, make the fence appear better, and make it endure longer, you should absolutely put in a gravel board for composite fencing. For composite fencing, a gravel board has the following benefits:

Provides Additional Protection

Composite materials are quite strong, but they can still be damaged. Many possible dangers come with long-term direct contact with soil:

Moisture and Microorganisms: If composite fencing is in a place with high humidity and poor ventilation for a long time, it can soak up small amounts of water. This lets algae, mold, and even moss develop. These germs not only make the fence seem terrible, but they can also wear down the surface of the material over time, which makes it weaker.
Stains and discoloration: The bottom of the fence panels is right on the ground, thus they can get stained quickly, which can make the whole fence seem ugly.
Physical Damage: Normal garden care or even a soccer ball hitting the bottom of the fence while the kids play can cause scratches and dents. Without a gravel board to protect the fence panels, this damage would have a direct effect on them.

So, a gravel board adds further protection to composite fencing. It takes in and lowers any hazards that might come from the earth, so your composite fence panels will last for many years.

Optimized Drainage and Ventilation

The health of a fence system depends not only on the materials used to make it but also on where it is put up. It is very important to have good drainage and ventilation.

Prevent Water Pooling: If you put fence panels directly on the ground, rain and irrigation water can easily pool at the bottom of the fence. There should be a tiny space between the ground and the gravel board in a well-designed system so that water may flow away easily.
Promote Air Circulation: Raise the fence panels to let air flow under the fence. Good airflow keeps the back of the fence dry, which helps the fence last longer overall.

Enhancing Aesthetics

Gravel boards can not only preserve the fence, but they can also make it look better.

Hiding Imperfections and Unevenness: Gravel boards go between the posts and can cover up any imperfections in the ground. This makes the barrier look like it goes on and on.
Enhancing Privacy: Gravel boards fill up the holes at the bottom of the fence, which makes the area more private. They also help the fence look stronger and more solid at the same time.

Which Gravel Board Is Best Suited for Composite Fences?

Once you’ve decided to put gravel boards on your composite fence, the following step is to pick the proper kind of material. Wood, concrete, and composite are the three primary varieties of gravel boards that you may buy. Each one has its own pros and cons and works well in certain situations.

Wooden Gravel Boards

Wooden gravel boards seem the most natural and warm, which is why they are a fantastic choice for classic fences. They are simple to use and cost less. The problem is that wooden dirt boards don’t survive very long. Even if the wood has been treated with a preservative, long-term exposure to wet dirt and grass clippings can create problems like rotting, cracking, and warping.

Concrete Gravel Boards

Concrete gravel boards are very hard to break. They don’t rot or bend, and you don’t have to worry about termites or other bugs getting into them. They create a very robust base for the fence because they are so hefty and strong. But their biggest problem is that they don’t look decent. They can mess up the overall look and harmony when set next to a nice composite fence.

Also, they are very heavy, so it takes a lot of work to move and set them up, which makes the installation expenses much higher.

Composite Gravel Boards

Composite gravel boards are the best choice when they are used with composite fencing. They are composed of the same material as composite fence, so they won’t rust, bend, or break. They preserve the rich colors and natural feel of wood at the same time.

Composite gravel boards are safer and easier to install than concrete, which saves money on labor. You can easily get gravel boards that match the color and texture of your composite fence.

But nice hybrid gravel boards normally cost more than regular wood. Still, they are a terrific long-term investment because they last so long and don’t need any maintenance.

FAQ

Are Gravel Boards Necessary in Areas with Good Drainage?

Even in regions with sufficient drainage, we strongly suggest putting down mud boards. Dirt boards do more than just keep water out. The water that is already there will rise, and the bottom of the fence panels will always be wet, even if the ground doesn’t hold water. The gravel board also does a fantastic job of protecting the surface from damage and stains.

Does the Gravel Board Block Ventilation at the Bottom of The Fence?

No. Leave the bottom edge of the gravel board 1 to 2 cm above the ground once it is in place. This space enables enough air through to dry things off without making the area appear unsightly or violating your privacy.

Can the Gravel Board be Replaced if it Becomes Damaged?

Sure. You simply have to fix the broken gravel board instead of the full fence panel if it gets hit or damaged by harsh weather. Most of the time, it only takes a few minutes and some basic tools to complete the thing. On the other hand, if the fence panel is broken, you may have to tear down a large part of the building, which will take longer and cost more.

Can I Install the Gravel Board Myself?

Installing gravel boards is easy for homeowners who have done some DIY work before. The difficulty level changes based on the kind of gravel boards you choose and how your fence is built.

Composite gravel boards are usually put in position by attaching them to posts using appropriate clips, screws, or bolts. It’s straightforward to understand and can be done by one person.
Wood gravel boards are easy to cut, but you need to treat them with a preservative first. They are usually held in place with screws or nails, so be careful not to split them.
Concrete gravel boards are very heavy, so they take a lot of work to move and set up correctly. You also require certain tools and skills to put up concrete gravel boards. A professional crew should undoubtedly do the fitting.
