Atak Truckings construction material calculator will help you estimate how many Cubic Yards of construction materials you will need for your desired coverage area. Our calculator will convert feet into cubic yards. The materials calculator offers 7 “Box/Rectangle” area fields (back yard, front yard, driveway, garden, etc..) and 4 “Circular” area fields (circular tree/plant beds) for you to calculate multiple areas simultaneously. The calculator works for construction materials including Topsoil, Dirt, Sand, Stone, Gravel, DGA, and Aggregate materials.
