Keystone’s patented, interlocking fiberglass pin system ensures positive connection between the structural wall unit and the soil reinforcement. Conklin Limestone Company carries the complete line of Keystone Retaining Wall Systems.  Call or email us for additional information and pricing.

Compac Unit

The Keystone Compac is the perfect choice where the deep embedment length of the Standard unit is not required.  An installer’s favorite, its lighter weight and shorter tail design makes it easy to handle for smaller walls.

The Keystone Mini is a great solution for smaller, non-critical applications.  It is easy to handle and easy to install. Makes for an attractive wall on its own or as an accent when integrated with the 8” high Standard or Compac units.  The proportion and scale of the Mini units blend well with brick and ledge stone typically found in residential construction.  The unit is also used for the 4” high cap module to complete most wall installations. The cap unit has a smooth top surface without openings to give a coping appearance.
