Timber Tanalised Gravel Boards are pressure-treated wooden boards installed horizontally along the bottom of a fence line, resting directly on or near the ground.

Featuring deep vacuum pressure-treatment (Tanalith E), they are primarily used for:

• Protecting Fence Panels from Ground Rot: Raising timber fence panels or vertical closeboard slats off damp soil, lawn, and standing water to prevent moisture absorption and bottom-up decay.

• Creating a Solid Soil Barrier: Retaining garden soil, mulch, bark, or gravel within flower beds and borders so it doesn't spill under the fence into a neighbouring garden.

• Filling Ground Gaps: Levelling out uneven lawn or soil gaps underneath fence panels to keep pets safely enclosed and prevent wild animals from burrowing under.

• Providing a Sturdy Base for Closeboard Fencing: Serving as the bottom anchor board that vertical feather edge boards rest on when building custom closeboard fencing from scratch.

Choosing between a timber or concrete gravel board depends on your budget, visual preference, and how long you want your fence to last.

• Choose Concrete Gravel Boards if you want maximum longevity and zero maintenance. Concrete never rots, warps, or decays from ground contact, making it a permanent solution. It creates a rigid base that works seamlessly with slotted concrete fence posts, though it is heavier and requires more effort to install.

• Choose Timber Gravel Boards if you prefer a natural wood finish or a lower upfront cost. Tanalised (pressure-treated) timber gravel boards blend in seamlessly with wooden fence panels and posts for a uniform aesthetic. They are lightweight, easy to cut to size, and cost less initially, though they will eventually need replacing every 5 to 10 years as ground moisture takes its toll.

How do I attach a timber gravel board to wooden fence posts?

Mount timber gravel boards using metal gravel board brackets (L-brackets or cleats). Screw the bracket into the inside face of the timber fence post, then screw through the bracket into the gravel board to hold it flush against the post. Alternatively, nail or screw directly through the face of the board into a small timber fixing block attached to the post.

Should a timber gravel board sit directly on the ground?

Ideally, clear a small channel beneath the board and fill it with pea shingle or gravel rather than letting the board sit directly in wet soil. While pressure treatment protects the wood, standing water and continuous soil contact will accelerate wear compared to a well-draining gravel bed.

Can I cut a timber gravel board to fit a shorter fence gap?

Yes. Cut the board using a standard hand saw or circular saw. Whenever you cut pressure-treated timber, treat the exposed raw wood end with an end-grain preservative treatment (such as Ensele or liberal coats of cut-end preserver) to maintain full rot resistance.
