Compac III Retaining Wall Blocks


The Keystone Compac III Retaining Wall Blocks are designed for larger, structural and commercial retaining wall projects; but just as useful in residential retaining wall applications. The Compac III is a shorter version of one of the most robust retaining wall blocks available, the Keystone Standard III. Use of either the Compac III or Standard III is determined by the engineering of the retaining wall project. The Compac III block comes standard in a traditional triface 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 Compac III is part of the Bella Vista Hardscape Collection.
