Description

6ft x 6inch Concrete Gravelboard – Recessed (150mm x 1830mm) – Lightweight

Protect your fence panels and get a neat, professional finish. This British Standard Approved recessed concrete gravel board lifts panels 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 6in (150mm) recessed concrete gravel board with:

• 6ft x 6ft fence panels (1830mm × 1830mm)

• 9ft slotted concrete posts

Together, this gives an overall height of approx. 6ft 6in (2.0m) — a popular setup that usually doesn’t need planning in many UK gardens (always check local rules).

High-Strength, Steel-Reinforced Concrete

Inside each gravel board are steel reinforcement bars that add strength and stiffness. This helps the board resist knocks, ground contact and everyday garden wear.

Lightweight for Easier Handling

A standard 6″ recessed concrete board is about 26.6kg.
Our lightweight version is 19.6kg — that’s ≈26.3% lighter.
You’ll notice the difference across a full day of fencing: less strain, quicker lifts, faster installs.

Keeps Panels Off the Ground

Timber panels absorb moisture when they touch soil or gravel. This speeds up rot and decay. The gravel board acts as a barrier, lifting the panel clear of the ground to help it last longer, especially in wet areas or along flower beds.

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 for the finish you prefer.

Quick, Compatible Installation

Designed for slotted concrete posts — just slot in with no brackets or fixings.
Use one board per 6ft bay for 6″ (150mm) ground clearance, or stack two for 12″ (300mm) where you need extra height.

• Use gloves and safe lifting: although lighter, it’s still concrete.

• Stacking: two boards can be used where a 12″ upstand is needed.

• Ground levels: great for levelling small variations and keeping bark, gravel or soil inside the garden edge. (Not a retaining wall.)
