7 DIFFERENCES BETWEEN MANUFACTURED AND NATURAL STONE September 17, 2019 DIFFERENCE #4: POPULAR TYPES. NATURAL STONE: All types of natural stone can be used for retaining wall blocks. The most common types for veneer applications are ledgestone and fieldstone. MANUFACTURED STONE: In this case “types” refer to the natural stone they try to imitate. In addition to fieldstone and ledgestone, another popular type is river rock. Sincerely, ZEMENT STONE September 17, 2019 Share on facebook Share on linkedin Share on email
