Concrete Anchors Minimum thickness of a concrete slab is 4 inches to use these anchors. Each anchor must have 4,725 Ibs of concrete to meet holding requirements. Concrete weighs approximately 4,000 Ibs per cu.yd. Each anchor requires approximately 1.2 cubic yards of concrete to meet holding requirements. Example:6 anchors on one side of a home would require over 7 cubic yards of concrete. Both sides would require over 14 cubic yards of concrete.
