Keystone Retaining Wall

When strength and longevity is needed, a Keystone retaining wall is the best choice. A Keystone retaining wall is comprised of modular concrete blocks that come in two sizes: Compac and Standard Units.  The Compac Units weigh about 80 pounds each and are 12″ deep. The Standard units weigh about 100 pounds each and are 21″ deep. Both types of Keystone units are connected with fiberglass pins and can support significant weight (or surcharge).  For strength, price and longevity nothing beats a properly built Keystone retaining wall.
