When it comes to maintaining the integrity and longevity of garden fencing, gravel boards play a crucial role. They serve as a protective barrier between the fence panels and the ground, preventing moisture, pests, and soil from damaging the wooden elements of your fence. In this comprehensive guide, we will explore the best gravel boards available, their benefits, and how to choose the right one for your garden fencing needs.

What Are Gravel Boards?

Gravel boards are horizontal barriers placed at the bottom of fencing panels. Typically made from wood, concrete, or composite materials, they elevate the fence panels off the ground, thereby extending their lifespan by protecting them from adverse conditions such as moisture and soil contact.

Why Use Gravel Boards?

  1. Protection from Moisture: Gravel boards prevent direct contact between the wooden fence panels and the damp ground, significantly reducing the risk of rot and decay.
  2. Pest Barrier: By creating a physical barrier, gravel boards help keep pests like termites and other insects from accessing and damaging the fence.
  3. Soil Retention: For gardens with uneven terrain, gravel boards also act as mini retaining walls, keeping soil in place and preventing erosion.
  4. Aesthetic Appeal: Gravel boards give a finished look to the fence, enhancing the overall appearance of your garden.

Types of Gravel Boards

1. Wooden Gravel Boards


  • Aesthetic: Complements wooden fencing panels for a uniform look.
  • Versatile: Easy to cut and fit to size.
  • Cost-effective: Generally more affordable than other materials.


  • Maintenance: Requires regular treatment to prevent rot.
  • Durability: Less durable compared to concrete or composite boards.

2. Concrete Gravel Boards


  • Durability: Extremely long-lasting and resistant to rot, pests, and weather conditions.
  • Low Maintenance: Requires minimal upkeep once installed.
  • Strength: Provides robust support for heavy fence panels.


  • Weight: Heavy and more challenging to install.
  • Cost: Generally more expensive upfront compared to wooden boards.
  • Aesthetic: May not blend as seamlessly with all fencing styles.

3. Composite Gravel Boards


  • Durability: Resistant to rot, pests, and weather, similar to concrete.
  • Aesthetic: Available in various colours and textures to match different fence styles.
  • Eco-friendly: Often made from recycled materials.


  • Cost: Can be more expensive than wooden boards.
  • Availability: May not be as widely available as wood or concrete options.

Choosing the Right Gravel Board

When selecting the ideal gravel board for your garden, consider the following factors:


Determine which material best suits your needs based on durability, maintenance requirements, and aesthetic preferences. Wooden boards offer a traditional look but require more upkeep. Concrete boards are robust and low-maintenance but can be cumbersome to install. Composite boards provide a balance of durability and aesthetic appeal but may come at a higher cost.


Ensure the gravel board size matches your fence panels. Standard sizes are typically around 150mm (6 inches) in height and 25mm (1 inch) in thickness, but measurements can vary. Custom-sized boards can be cut to fit unique fencing layouts.


Evaluate the initial cost as well as the long-term maintenance expenses. Wooden boards are more budget-friendly initially but may incur higher maintenance costs. Concrete and composite boards, while more expensive upfront, tend to have lower long-term maintenance expenses.


Consider the ease of installation based on your DIY skills or the availability of professional help. Wooden boards are generally easier to install, whereas concrete boards may require additional labour due to their weight.

Installation Tips

  1. Preparation: Clear the area of any debris and ensure the ground is level before placing the gravel boards.
  2. Secure Fixing: Use appropriate fixings or brackets to attach the gravel boards securely to the fence posts.
  3. Alignment: Ensure the boards are level and aligned correctly to provide a stable base for the fence panels.
  4. Sealing Joints: If using wooden gravel boards, apply a water-resistant sealant to the joints to prevent moisture ingress.

Maintenance Tips

Wooden Gravel Boards

  • Treat with a wood preservative annually to protect against rot.
  • Regularly inspect for signs of damage or decay and address promptly.

Concrete Gravel Boards

  • Check periodically for cracks or chips and repair with concrete filler as needed.
  • Keep the surface clean to prevent moss or algae build-up.

Composite Gravel Boards

  • Clean with a mild detergent and water to remove dirt and grime.
  • Inspect periodically for any signs of wear or damage.


Gravel boards are an essential component for long-lasting garden fencing.
