Gravel Board
Premium British Timber Gravel Board Solutions
A gravel board forms the foundation of any long-lasting perimeter boundary. By lifting decorative fence panels directly off wet turf and soil, it prevents moisture absorption from rotting delicate framing battens. Our trade-grade boards provide a dependable defence against ground surface moisture, garden pests, and strimmer impacts across residential gardens and large estate boundaries.
Every run of timber we profile is precision-cut from slow-grown, sustainably sourced softwood. Unlike flimsy panels that warp after a single wet British winter, these boards offer structural rigidity across every linear metre. You can pair them smoothly with our wider collection of fencing, gates, and trellis panels to create a cohesive exterior aesthetic.
Whether you are erecting a private boundary run or completing a perimeter for high-traffic commercial sites, these components deliver peace of mind. We also supply matching brackets, posts, and fixings within our comprehensive fence and gate accessories collection to help you complete the installation without delay.
Delivers clearance to isolate fence panels away from sitting surface water.
Substantial timber sections that prevent bowing under lateral earth pressure.
Precision sizing mapped directly to standard 6ft panel and post spacings.
Deep chemical penetration engineered for continuous ground contact.
Timber Selection and Preservation Methods
The longevity of any boundary installation relies entirely on selecting the right timber species. We choose responsibly harvested European redwood and British larch because their tight cellular grain resists physical impact, split development, and natural weathering far better than fast-grown budget timbers.
To provide complete subterranean longevity, every section undergoes an advanced high-pressure treatment method inside industrial autoclave cylinders. Preservative salts are driven deep into the timber sapwood under strict vacuum cycles rather than given a quick dip wash. This process ensures high soil rot resistance across wet lawns, heavy clay beds, and shaded areas.
This deep chemical saturation makes maintenance easy while retaining natural grain patterns. When integrated alongside our heavy-duty outdoor wooden planters, your landscaping scheme achieves an authentic natural finish without early fungal decay.
Ground Contact Durability
Our pressure treatment cycles meet BS 8417 standards to guarantee 15 years of protection against wet rot and fungal attack.
Architectural Style and Capping Profiles
Gardeners often compare concrete vs wooden style gravel boards when designing their garden runs. While concrete offers raw density, it produces a cold industrial finish that chips easily and risks cracking during hard winter frosts. In contrast, planed timber gravel boards offer a warm, natural aesthetic that matches featheredge runs and slatted decorative screens seamlessly.
Our profiles are engineered with integrated capping rail compatibility in mind. Adding a matching timber capping rail locks the upper line of the board against the bottom fence frame, shielding horizontal end-grain seams from driving rain. This connection also deters burrowing pets and stops weed growth from creeping into panel gaps.
We supply both standard lengths for straight fence runs and longer dimensions for custom sloped installations. If you need bespoke sections to finish high-profile hospitality or public garden installations, explore our previous bespoke layouts within our commercial projects portfolio.
Clean Boundary Integration
Straight, square-edged board profiles slide cleanly into standard slotted timber posts or fix firmly against flat wooden stakes.
Three Core Structural Advantages
Every gravel board is profiled to protect fencing systems from physical damage, harsh weather, and ongoing soil moisture.
Continuous Moisture Isolation
Lifting your primary fence framework 150mm away from wet ground interrupts moisture wicking. Softwood panel slats quickly decay if allowed to rest in pooling autumn rainwater or moist soil beds.
A dedicated, sacrificial gravel board absorbs soil contact instead. When replacement is eventually needed decades later, swapping an affordable base board is far simpler than rebuilding entire panels.
Lawn Edging and Physical Protection
Nylon strimmer cords and lawnmower decks cause substantial damage to boundary boundaries over time. Thin featheredge pales splinter and break when struck, exposing unfinished internal timber fibres to spores.
Our dense board thickness forms a sturdy impact barrier against routine garden machinery. This keeps the delicate bottom edges of your fencing panels neat, clean, and structurally intact.
Soil Retention on Sloping Lawns
Gardens situated on uneven hillsides often suffer from soil movement between adjoining properties. A secure gravel board works as a low-level retaining barrier, holding back topsoil, decorative bark, or gravel.
This foundation prevents soil washouts after heavy storms. It establishes a neat, level baseline for boundary panels without requiring expensive terracing or structural retaining walls.
Technical Quality and UK Sourcing Standards
Every timber section we distribute is milled in accordance with stringent UK trade tolerances. We source raw material solely through FSC and PEFC certified supply chains, ensuring responsible forest management and traceable environmental credentials across all stock.
Our boards comply fully with BS 8417 specifications for preservative treatment penetration. Softwood components intended for direct soil contact are dried to optimal moisture levels before entering the treatment vessels, allowing the active ingredients to bond firmly within the wood cells.
These high standards explain why local authorities, school premises, and private developers rely on our products for their boundary works. Whether updating play facilities or enhancing residential grounds, our timber provides lasting stability you can trust.
Dimensional Tolerances
Profiles are planed with strict plus or minus 2mm width tolerances to ensure a clean slide fit into standard concrete and timber intermediate posts.
Professional Advice and Delivery Support
Selecting the ideal dimensions for complex garden boundaries requires careful calculation. If you are planning an extensive installation across difficult sloping ground, our experienced team is on hand to review your measurements and advise on post spacing, board heights, and compatible hardware.
We manage order distribution with dedicated vehicle fleets across mainland Britain, ensuring your goods arrive safe and undamaged. For qualifying project sizes, you can take advantage of our nationwide free delivery service directly to your site or residential address.

Frequently Asked Questions
What is the primary function of a gravel board
A gravel board elevates horizontal fence panels away from damp soil and standing water. This physical barrier stops moisture absorption, preventing premature wet rot and keeping panels sound for years longer.
Should I choose a timber or concrete gravel board
Timber gravel boards blend smoothly with wooden fence panels, creating a cohesive natural look without the risk of frost cracking. Concrete boards are heavier and more industrial, making timber the preferred choice for residential gardens.
Can these boards be cut to bespoke lengths on site
Yes, standard timber boards can easily be trimmed using a standard hand saw or circular saw. We recommend treating all freshly cut ends with an end-grain preservative solution to keep the wood sealed against moisture.
How do I fix gravel boards to intermediate posts
Our gravel boards slide easily into the recessed channels of slotted timber or concrete posts. For square-sawn posts, you can secure them directly using heavy-duty galvanised metal gravel board brackets and exterior screws.
Do your gravel boards hold back garden soil on slopes
Our boards easily support low soil level differences up to 150mm on gentle inclines. For taller slopes or heavier earth retention, we recommend using double-stacked boards reinforced with intermediate timber retaining stakes.
