Standard III Retaining Wall Blocks


The Keystone Standard III Retaining Wall Blocks are designed for larger, structural and commercial retaining wall projects; but just as useful in residential retaining wall applications. The Standard III is the most robust retaining wall block available. A shorter/lighter version of the Standard III, the Compac III, is available. Use of either is determined by the engineering of the retaining wall project. The Standard III block comes standard in a traditional tri-face design; but specialty faces such as the Stone Face and California Chateau are also available.

  • Retaining Walls up to 50' with engineering
  • Excellent for straight, curved, and terraced retaining wall designs
  • Connect units using specialized fiberglass pin system

The Keystone Standard III is part of the Bella Vista Hardscape Collection.
