A pre-mix of sand and gravel that is ideal for mixing concrete, which is cheaper then purchasing small bags of the ready-to-use concrete. Simply mix cement and water to make your desired concrete slump and strength. Ideal for small to medium pours like setting fence or sign posts, shed slabs, footings, foundation and retaining walls, and the perfect aggregate blend for the home DIY projects like the custom built fish pond or bird bath.
