Timber Gravel Boards 150 x 22mm, Square Edged, Pressure Treated, Green or Brown, 1.83m to 3.6m

These square-edged gravel boards are for anyone building or repairing a timber fence who wants the panels or feather edge boards kept clear of the soil. Each 150mm x 22mm board fits at the base of the fence between the posts, where it takes the ground splash and damp that would otherwise soak into the bottom of your panels. Fencing contractors, landscapers and homeowners fit them for a practical reason: when a gravel board wears, you replace that board alone, far more cheaply than a panel. The boards are pine/spruce mix, pressure treated and rough sawn, in Green treated (1.83m, 3m, 3.6m) or Brown treated (3m).

Why it works

It keeps the fence off wet ground

Timber in contact with damp earth stays wet, and wet timber is where rot starts. A 150mm board at the base lifts your panels or feather edge boards clear of the soil, so the gravel board takes the splash and damp instead of the fence above it.

It is the part you replace, not the panel

Because the gravel board is a separate component, you can fit a new one when it wears without replacing the panel. That is a far cheaper repair and keeps the fence line intact.

Pressure treatment slows decay

The pine/spruce mix is pressure treated to improve resistance to insect attack and rot. Treatment slows decay rather than stopping it, so plan on replacing the board eventually, sooner where the ground stays wet.

Lighter and simpler than concrete

At 4-8kg per board depending on length, timber is lighter to handle, easier to cut and fix, and more cost-effective than concrete gravel boards. The trade-off is plain: in permanently wet ground, timber will not last as long as concrete.

Where it's used

You will find these boards along domestic garden boundaries at the foot of 6ft panel fences, and under closeboard and feather edge fences on post-and-rail framing. Contractors use the longer lengths on new boundary runs for landscaping and new-build plots. They are also a straightforward repair where an existing gravel board has rotted, and a sensible choice in side passages where soil or gravel is banked against the fence.

Specifications

Choosing the right option

Length

The 1.83m board suits standard 6ft (1.83m) panel bays between posts, one board per bay. The 3m and 3.6m boards suit post-and-rail or closeboard runs with wider post spacing, or you can cut them down to fit two shorter bays with less waste. The 2.4m length is currently unavailable in both colours.

Colour

Brown treated is offered in 3m only, so if you need 1.83m or 3.6m, choose Green treated. Either colour weathers to silvery grey; an annual stain or preservative maintains the colour.

Timber or concrete

If the base of your fence sits in permanently wet ground, a concrete gravel board will outlast timber.

Installation, use & care

Fix each board to timber posts with galvanised screws or gravel board clips or brackets, or to a centre stump or cleat. Leave a small gap between the bottom edge and the ground so the board isn't buried. Treat any freshly cut ends with an end-grain preservative before fitting. To hold the colour, apply a stain or preservative once a year; otherwise the board will weather to silvery grey. When a board wears out, replace it on its own.

FAQ

Will a timber gravel board last as long as a concrete one?

No. In permanently wet ground, timber will not last as long as concrete. Timber is lighter, easier to cut and fix and more cost-effective, and a worn board can be replaced on its own far more cheaply than a panel.

Can I cut the 3m or 3.6m boards to fit my bays?

Yes. The longer lengths are often cut down to fit two shorter bays with less waste, which also covers wider bays now that 2.4m is unavailable. Treat every freshly cut end with an end-grain preservative before fitting.

Will the green or brown colour fade?

Yes. Treated softwood weathers to silvery grey over time, whichever colour you choose. To keep the green or brown look, apply a stain or preservative once a year. Weathering is a change in appearance only.

What treatment use class and service life does this board have?

Neither is published for this line. What is stated is that the boards are pressure treated to improve resistance to insect attack and rot, and that timber will not last as long as concrete in permanently wet ground.
