Concrete gravel boards are used in fencing installations to extend the life of timber fence panels by lifting them clear of ground contact. By separating fence panels from soil and surface water, concrete gravel boards significantly reduce the risk of damp, rot, and fungal decay—particularly in gardens with poor drainage or exposed ground conditions.
These gravel boards are designed to slot neatly into concrete slotted fence posts, creating a strong, stable base for long-lasting, low-maintenance fencing.
Strong, Steel-Reinforced Construction
Manufactured from dry-cast concrete and reinforced with internal steel rods, our concrete gravel boards are produced to meet BSI standards for strength and durability. The dry-cast manufacturing process delivers a smooth, consistent finish with minimal surface bubbles, while keeping overall weight lower than traditional wet-cast alternatives.
This makes the boards easier to handle on site while still providing excellent resistance to impact, weathering, and long-term ground moisture.
Suitable Applications
Concrete gravel boards are commonly used for:
Domestic garden fencing
Boundary fencing exposed to damp ground
Panel fencing requiring extended service life
Replacement of timber gravel boards in existing fence runs
They provide a durable alternative to timber gravel boards where longevity and reduced maintenance are a priority.

Can Concrete Gravel Boards Be Stacked?
Yes. Concrete gravel boards can be stacked vertically within concrete slotted posts to form a continuous concrete fence base or even a full concrete panel fence. This approach is often used where additional durability is required, such as in high-moisture areas or locations prone to impact damage.
Stacking gravel boards creates a robust, long-lasting structure that offers excellent resistance to ground moisture and wear.
