When it comes to maintaining a garden or property, fencing often takes centre stage. Not only does a fence provide security and privacy, but it also adds to the aesthetic appeal of the space. However, a crucial element often overlooked in fencing installations is the gravel board. This seemingly simple component plays an essential role in prolonging the lifespan and effectiveness of your fence panels. In this comprehensive blog post, we’ll delve into why gravel boards are indispensable for protecting fence panels.

What are Gravel Boards?

Gravel boards are narrow, horizontal planks usually made from wood, concrete, or composite materials. They are installed at the base of fence panels, sitting between the ground and the panel itself. Despite their unassuming appearance, gravel boards provide several important functions that can significantly enhance the longevity and durability of your fencing.

Key Functions of Gravel Boards

1. Protection Against Rot and Moisture

One of the primary reasons to install gravel boards is to protect the bottom of your fence panels from rot and moisture. When wood comes into direct contact with soil, it absorbs moisture, leading to rot and decay over time. By elevating the fence panels off the ground, gravel boards act as a barrier, preventing direct contact with damp soil and significantly reducing the risk of rot.

2. Mitigating Soil Erosion

Soil erosion can be particularly damaging to fences, especially those installed on sloping terrain. Eroding soil can undermine the stability of the fence posts and panels, causing them to lean or collapse. Gravel boards help to stabilise the soil around the base of your fence, providing a solid foundation that minimises the effects of erosion and maintains the integrity of your fencing structure.

3. Pest Prevention

Gravel boards can also serve as a deterrent to pests such as termites and insects, which are notorious for damaging wooden fence panels. The boards act as a physical barrier, making it difficult for pests to access and infest the fence panels. In this way, gravel boards contribute to the overall health and longevity of your fence.

4. Enhancing Aesthetic Appeal

A well-maintained fence not only serves a functional purpose but also enhances the visual appeal of your property. Gravel boards can add a neat and finished look to your fencing installation, covering any unsightly gaps at the base of the fence and creating a uniform appearance. Additionally, they can be painted or stained to match the colour of your fence panels, further enhancing the overall aesthetic.

5. Easy Replacement and Maintenance

Over time, the base of a fence is likely to experience wear and tear due to exposure to the elements. Gravel boards offer an easy and cost-effective solution for maintenance. Rather than replacing entire fence panels, you can simply replace the gravel boards if they become damaged. This ease of replacement helps to extend the lifespan of your fence panels and reduces long-term maintenance costs.

Types of Gravel Boards

Gravel boards come in various materials, each with its own set of benefits:

Wooden Gravel Boards

Wooden gravel boards are a popular choice due to their natural appearance and ease of installation. They can be painted or stained to match the fence panels, providing a cohesive look. However, they may require regular maintenance and treatment to prevent rot and pest infestation.

Concrete Gravel Boards

Concrete gravel boards are highly durable and require minimal maintenance. They are resistant to rot, moisture, and pests, making them an excellent choice for long-term protection. However, they can be heavier and more challenging to install compared to wooden boards.

Composite Gravel Boards

Composite gravel boards are made from a blend of wood fibres and plastic, combining the best features of wood and concrete. They are resistant to rot, moisture, and pests, while also being lightweight and easy to install. Composite boards offer a modern, sleek appearance and require minimal maintenance.

Installation Tips for Gravel Boards

Installing gravel boards is a straightforward process that can be accomplished with basic tools and materials. Here are some tips to ensure a successful installation:

  1. Measure and Cut: Measure the length of your fence panels and cut the gravel boards to size. Ensure the boards are level and fit snugly against the base of the panels.
  2. Secure in Place: Use galvanised screws or brackets to secure the gravel boards to the fence posts. This will provide stability and prevent movement over time.
  3. Treat and Seal: If using wooden gravel boards, treat them with a wood preservative to protect against rot and pests. Apply a sealant to enhance durability and extend the lifespan of the boards.
  4. Regular Maintenance: Periodically inspect the gravel boards for signs of damage or wear. Replace any damaged boards promptly to maintain the integrity of your fence.


Gravel boards may seem like a minor component in a fencing installation, but their importance cannot be overstated. From protecting against rot and moisture to preventing soil erosion and pests, gravel boards play a vital role in ensuring the longevity and effectiveness of your fence panels. By investing in quality gravel boards and following proper installation and maintenance practices, you can enjoy a sturdy, attractive, and long-lasting fence that enhances the value and appeal of your property.

For those looking to install or upgrade their fencing, consider incorporating gravel boards as an essential component. Your fence—and your property—will thank you for it.
