Concrete Gravel Boards

Concrete Gravel Boards

Shop concrete gravel boards for a strong, rot-resistant base beneath timber fence panels. Installed between compatible slotted concrete posts, they help raise the panel away from damp soil, rain splash and garden debris.

Choose from popular heights and surface finishes, including practical smooth designs and more decorative recessed options across suitable products. Lower boards provide straightforward ground clearance, while taller boards create a more substantial base and add further height to the completed fence.

Check the board length, thickness and profile against the post system before ordering. Concrete gravel boards are heavy, but once installed they provide a durable, low-maintenance foundation for garden fencing.
