Keystone Garden Wall® LANDSCAPE RETAINING WALL BLOCK
A do-it-yourself retaining wall tradition, Keystone Garden Wall is perfect for landscape walls up to 2-feet (60cm) in height as well as tree rings, edging, raised gardens and borders. Utilizing the rear-lip alignment method, Garden Wall easily builds straight, curved or terraced walls to fit the contours of your yard. Keystone Garden Wall is known as Arbor Stone or Castle Wall in some markets.
