There is no better way to protect the base of your fence panels than with our Lightweight Concrete Gravel Boards 1.83m. When exposed to ground contact, wooden fence panels can be quickly affected by ground moisture which, over time, causes them to rot and decay. Concrete gravel boards are the most effective barrier to ground moisture and will provide superb protection to your fence panels. At just 18kg, these gravel boards are surprisingly lightweight when compared to equivalent products which makes for a quick and easy installation. Featuring a unique removable \"nib\" design, the boards are compatible with both 1800mm and 1830mm panels. Please note – We recommend the use of a recognised mechanical cutting tool if removing the \"nibs\". Give your fence panels the best protection against ground moisture with our Lightweight Concrete Gravel Boards. Clever \"nib\" design allows for use with 1800mm and 1830mm wide fence panels (recognised mechanical cutting tool required to remove \"nibs\"). Comparatively lightweight when put up against equivalent products, you can expect easier movement and installation. Concrete gravel boards are not susceptible to rust, rot and decay. Water is deflected rather than absorbed. With superior durability our gravel boards will last longer than average timber boards.
