The versatile and easy-to-use design of Diamond® retaining wall systems has made them the preferred choice of contractors for decades. The Diamond® 9D retaining wall blocks have the advantages of an easy-to-handle light weight and a beautifully distressed appearance.

• Gravity walls can be built up to 3 feet high, including buried course, but
  excluding the cap*
• Taller walls can be built using geosynthetic reinforcement or the
  Anchorplex™ retaining wall system when designed by a qualified engineer
• Min. outside radius, measured on the top course to the front of the units: 3ft
• Min. inside radius, measured on the base course to the front of the units: 6t

*This height assumes cores are filled with drainage aggregate,
level backfill and clean, compacted sand or gravel and no surcharge
