12-Inch x 6ft Concrete Gravelboard – Recessed and Lightweight
Protect your fence panels and create a neat, professional finish with our 300mm x 1830mm recessed concrete gravelboard. It keeps timber panels approximately 300mm (12 inches) above ground level, helping reduce moisture contact and extend their usable life.
Manufactured from steel-reinforced concrete using a lighter mix, this gravelboard provides dependable strength while being easier to handle than a standard 12-inch concrete board.
Commonly Used With
This gravelboard is commonly paired with:
- 6ft x 6ft fence panels (approximately 1830mm x 1830mm)
- 10ft slotted concrete posts
A 6ft panel installed above a 12-inch gravelboard creates an overall fence height of approximately 7ft (2.1m). This may exceed local permitted-development limits, so check the planning requirements for your location before installation.
Steel-Reinforced Concrete
Steel reinforcement bars provide additional strength and stiffness. The concrete construction is designed to withstand ground contact, everyday knocks and normal outdoor exposure.
Lightweight for Easier Handling
A standard recessed 12-inch gravelboard weighs approximately 46.3kg. This lightweight version weighs approximately 32.5kg—around 30% lighter and approximately 13.8kg less.
The reduced weight makes the board easier to lift, carry and position during installation while retaining the benefits of reinforced concrete construction.
Keeps Timber Panels Clear of the Ground
Timber fence panels can absorb moisture when they come into direct contact with soil, bark or mulch. The 300mm gravelboard creates a protective barrier between the panel and ground, helping reduce the risk of premature rot and decay.
Recessed or Smooth Finish
One face has a traditional recessed finish suitable for closeboard and lap-style panels, while the reverse face is smooth. Either side can face the garden depending on the finish you prefer.
Compatible Installation
Designed for use with slotted concrete posts, the gravelboard slots into position without separate brackets or fixings. One board is normally used for each 6ft fencing bay.
