When it comes to constructing a durable and long-lasting fence, many people focus on the choice of panels, posts, and gates. However, an often-overlooked component plays a crucial role in extending the life and effectiveness of your fencing: gravel boards. In this comprehensive guide, we will delve into what gravel boards are, their types, benefits, and why they are essential in any fencing project.

What Are Gravel Boards?

Gravel boards are horizontal planks that sit at the bottom of your fence, positioned between the ground and the fence panels. They are typically made from materials like wood, concrete, or composite, and come in various sizes to suit different types of fences. Their primary function is to act as a barrier between the soil and the fence panels, preventing potential damage caused by moisture, pests, and garden debris.

Types of Gravel Boards

  1. Wooden Gravel Boards
  • Material: Typically made from treated timber to resist rot and decay.
  • Aesthetics: Offers a natural look that blends seamlessly with wooden fence panels.
  • Lifespan: Generally shorter lifespan compared to concrete and composite options, but can last several years with proper maintenance.
  1. Concrete Gravel Boards
  • Material: Made from reinforced concrete to withstand harsh weather conditions.
  • Durability: Highly durable and resistant to rot, pests, and moisture.
  • Appearance: Can be painted or left natural; may not blend as well with wooden panels but provides a modern, sturdy look.
  1. Composite Gravel Boards
  • Material: A mix of wood and plastic, offering the best of both worlds.
  • Benefits: Resistant to rot and pests, and does not require painting or staining.
  • Aesthetics: Available in various colours and finishes to match different fence styles.

Why Gravel Boards Are Important

  1. Protection Against Moisture
  • Fences are constantly exposed to moisture from rain, irrigation systems, and groundwater. Gravel boards act as a buffer, preventing direct contact between the fence panels and the damp ground. This reduces the risk of rot and extends the lifespan of your fencing materials.
  1. Pest Prevention
  • Wooden fence panels are susceptible to damage from pests like termites and ants. By installing gravel boards, you create a physical barrier that makes it more difficult for pests to reach and infest your fence.
  1. Maintaining Fence Stability
  • Gravel boards provide additional stability to your fence by anchoring the panels firmly to the ground. This is particularly crucial in areas with uneven terrain or loose soil, where shifting ground can compromise the integrity of your fence over time.
  1. Aesthetic Appeal
  • Gravel boards can enhance the overall look of your fence by providing a clean, finished edge at the bottom. This is especially beneficial for gardens with a neatly manicured appearance, as it helps define the boundary between your garden and the fence.
  1. Erosion Control
  • In gardens with slopes or uneven ground, gravel boards can help prevent soil erosion by acting as a retaining barrier. This ensures that soil and garden debris do not accumulate against the fence, which can cause sagging and instability.

Installation Tips

  1. Measure Accurately
  • Before purchasing gravel boards, measure the length of your fence panels to ensure you buy the right size. Gravel boards typically come in standard lengths, but custom sizes are also available.
  1. Prepare the Ground
  • Clear the area where the gravel boards will be placed, removing any rocks, roots, or debris. Level the ground as much as possible to ensure a stable base for the boards.
  1. Secure Properly
  • Use appropriate fixings to securely attach the gravel boards to the fence posts. For wooden gravel boards, galvanised screws or nails are recommended. Concrete gravel boards may require special brackets or clips for secure installation.
  1. Maintenance
  • Regularly inspect your gravel boards for signs of wear and tear. Wooden boards may require periodic treatment with preservatives to maintain their resistance to rot and decay. Concrete and composite boards generally require minimal maintenance.


Gravel boards are an essential component in any fencing project, offering protection, stability, and aesthetic appeal. Whether you opt for wooden, concrete, or composite gravel boards, incorporating them into your fence design will significantly extend the life of your fencing and enhance its overall performance. By understanding the importance of gravel boards and following best practices for installation and maintenance, you can ensure a durable and attractive fence that stands the test of time.
