The 1.83m recessed concrete gravel board has been designed for use with our concrete slotted posts. Due to the recessed design, this product is very easy to install as everything slots into place. Without a gravel board you stand the risk of timber rot caused by ground moisture coming into contact with the bottom of the fence. The recessed concrete gravel board will act as a barrier between the ground and the timber. It will also ensure soil or gravel stays inside your own garden. You also have extra protection as a concrete gravel board cannot rot like the timber alternatives. This hard wearing product is ideal for all garden fences using either lap panels or closeboard panels with concrete slotted posts.
