The team of experts at Sandee’s Rock & Soil will help you determine how much decorative rock you will need to complete your landscaping project. Typically, one yard of rock will cover 100 square feet of area to a depth of two inches. But that may not always be the case. We are happy to consult with you regarding your landscaping vision before estimating how much landscaping rock will be necessary to achieve it. You can also use our convenient materials calculator if you know the width, depth, and length of the area you are enhancing.
