Timber gravel boards are an essential piece of many garden features. They are used as a retainer, to prevent small amounts of soil from accessing the base of fences. This means that they prevent a full range of fencing solutions, from fencing boards to panels and even closeboard fencing from rotting due to constant exposure to harmful elements.
They provide an effective barrier between the ground and the fence, which can be essential when the ground is wet or damp. This allows your border to avoid damage from moisture and other potentially harmful ingredients.
