WebA post hole digger is a gardening tool used to dig narrow holes to install posts, such as for fences or signs. A post hole pincer is jabbed into the ground in the open position until the blades are buried. At that point, the handles are pulled apart to close the tool, grabbing the chunk of soil that has been loosened. Manufactured sand (M sand) is sand made from rock by artificial processes, usually for construction purposes in cement or concrete. It differs from river sand by being more angular, and has somewhat different properties. WebTypically Asphalt Sand is used to manufacture Hot Mixed Asphalt. It is also used in sports fields, as well as can also be used to amend soils soil (to help loosen up the clay and improve soil structure).
