Plastic Gravel Boards 150mm – Damp Prevention & Protection

Protect your fence panels from ground moisture and decay. These lightweight, durable plastic gravel boards function as an effective damp course, keeping timber panels elevated and dry while offering superior performance to traditional concrete alternatives.

Essential Foundation Protection

Moisture Barrier Gravel boards elevate fence panels above ground level, preventing direct soil contact and protecting timber from ground moisture, dampness, and rot. Acting as an effective damp course, they significantly extend the lifespan of timber panels.

Ground Clearance. By creating a protective gap between timber and soil, gravel boards eliminate one of the primary causes of timber decay. This simple elevation dramatically improves fence longevity and reduces maintenance demands.

Superior to Concrete

Lightweight Design Unlike heavy concrete gravel boards, plastic versions are easy to handle and position—no specialist equipment or labour required. Single-person installation is straightforward and quick.

Better Performance Plastic gravel boards don't crack, fracture, or degrade like concrete. They remain structurally sound and protective indefinitely, maintaining their moisture-blocking properties throughout their lifespan.

Easy Customisation: Cut to precise length on-site using standard tools. Fit exactly like traditional concrete gravel boards but with superior handling and durability.

Robust Construction

6-foot Width Standard 1829mm length boards provide efficient coverage and straightforward installation. Cut to custom lengths to suit your specific fence layout.

150mm Height Provides substantial ground clearance to protect timber panels while maintaining a practical, proportioned appearance.

Post Compatibility Designed to work seamlessly with our plastic post systems, accommodating timber panels up to 50mm thick.
