The B&Q Smooth Concrete Gravel Board 10-pack is designed for homeowners and professional landscapers looking to extend the lifespan of their timber fencing. These reinforced boards provide a durable, moisture-resistant barrier at the base of your fence, effectively preventing rot and pest damage by lifting panels away from damp soil. While they offer superior protection and stability, users should be prepared for the heavy lifting required during installation due to the dense, reinforced concrete construction.

While exact weight varies by specific mix density, these reinforced boards are heavy and should be treated as a two-person lift.
Yes, you can use specialized masonry paint to change the color, though the factory-applied grey finish is designed to be weather-resistant on its own.
No, the concrete is factory-cured and designed for outdoor use without additional sealants.
They are designed for standard 1830mm (6ft) width panels. If your panels are non-standard, you will need to adjust your post spacing accordingly.
These boards are designed for fencing support and are not intended for structural retaining wall applications where significant soil pressure exists.
Check the post for debris or concrete residue in the channel and remove with a chisel. Ensure the post is perfectly plumb.
Use a spirit level during installation. You may need to excavate a small amount of soil beneath the board to bring it into the correct position.
Small chips can be repaired using a concrete repair compound matched to the grey color of the boards.
To install, ensure your fence posts are set at the correct distance of 1830mm center-to-center to accommodate the boards. If using concrete slotted posts, simply slide the board into the channels before mounting the fence panel. If using timber posts, purchase specialized gravel board brackets to secure the boards to the post faces. Because the boards are heavy, always use proper lifting techniques and wear safety footwear to prevent injury. To clean, a simple wash with a pressure washer or a hose and stiff brush is sufficient to remove mud or moss buildup. Avoid using harsh chemical solvents that could degrade the concrete surface.
