3.0m x 150mm x 22mm Wooden Gravel Board – Pressure Treated Brown

Long-Span Gravel Board for Timber Fencing Systems

This 3.0m x 150mm x 22mm brown wooden gravel board offers extended coverage for large bays or custom-length fencing projects. Manufactured from softwood and pressure treated to UC4 standards, it acts as a protective barrier at the base of your closeboard fencing, safeguarding the vertical boards from splashback and ground rot.

With its long 3.0m span, this gravel board reduces the number of joins needed, improving installation speed and visual continuity across larger boundaries. Often used in both residential and commercial fencing, it pairs perfectly with featheredge boards and helps achieve a clean, professional finish.

When combined with a 1.80m feather edge board, this gravel board lifts the finished height to around 1.95m.

Materials related to “Gravel Board”

• Featheredge Boards – Fixed above the gravel board to form the main face of the fence.

• Cant Rails – Horizontal supports for the feather edge boards.

• Wooden Fence Posts – Treated timber posts for full wooden fencing systems.

How do you install a wooden gravel board?

Begin by positioning and securing your fence posts with Postcrete. Align the gravel board horizontally between posts at the base and attach it using galvanised nails, timber screws, or bolts. This sets a level base line for cant rails and feather edge boards, helping maintain height consistency across the fence.
