12inch x 6ft Concrete Gravelboard – Recessed (300mm x 1830mm) – Lightweight
Protect your fence panels and get a neat, professional finish. This British Standard Approved recessed concrete gravel board lifts panels 300mm (12″) off the ground to reduce rot and extend life. It’s steel-reinforced for strength and made in a lighter mix for easier handling on site.
Commonly Used With
Most customers pair this 12″ (300mm) recessed concrete gravel board with:
6ft x 6ft fence panels (1830mm × 1830mm)
10ft slotted concrete posts
This gives an overall height of approx. 7ft (2.1m) with a 6ft panel. That’s above the usual 2.0m limit in many UK gardens, so check local planning rules before installing.
High-Strength, Steel-Reinforced Concrete
Each gravel board includes steel reinforcement bars for extra strength and stiffness. It resists knocks, ground contact and everyday garden wear.
Lightweight for Easier Handling
A standard recessed 12″ gravel board is around 46.3kg.
Our lightweight version is 32.5kg — that’s ≈30% lighter (13.8kg less).
Result: less strain, quicker lifts, faster installs across a full day.
Keeps Panels Well Clear of the Ground
Timber panels absorb moisture when they touch soil or bark. This speeds up rot and decay. With a full 300mm upstand, the gravel board acts as a barrier, helping panels last longer—especially in wet beds, along hedges, or where mulch touches the fence line.
Clean, Recessed Finish
One face is recessed for the classic look under closeboard and lap panels; the other is smooth. Choose which side faces the garden.
Quick, Compatible Installation
Designed for slotted concrete posts — simply slot in with no brackets or fixings.
Typically one board per 6ft bay is used at this height.
