Also known as “washed sand,” Concrete Sand is another by-product of materials manufactured at aggregate washing plants. Soil and rocks are dug from the earth and then washed to separate the various particles sizes to provide washed gravels and sands.  Concrete sand is commonly used in concrete work but is also used in various landscaping mixes as it provides additional drainage when blended with compost, soil and mulches.  It is also ideal for use on ice to help prevent slipping during winter storms.
