The gabion wall system consisted of approximately 21,230 square feet of permanent hillside stabilization constructed to support multiple areas of the property designated for future development and pedestrian roadway access. The walls reached heights of up to 24 feet and required a durable architectural finish that would visually integrate with the surrounding masonry and match the established colour palette used throughout the site.A primary concern on the project was the performance of locally sourced pahoehoe lava stone, which had been used extensively across the islands but was found to deteriorate over time. In several installations, the stone had loosened and fallen from masonry walls, creating safety hazards for pedestrians below. To address both aesthetic and safety requirements, Boulderscape developed a sculpted architectural shotcrete finish that replicates the appearance of local lava masonry while providing a compressive strength of approximately 4,000 psi, eliminating the risk of material erosion or falling debris.This custom finish, designated the G8 Hawaiian Lava finish, was reviewed and approved through mockups prior to full installation. Following approval, Boulderscape collaborated with Tensar to design the retaining wall system to accommodate the shotcrete facing. Once the structural system was approved, shotcrete was applied over the SierraScape system.         .After placement, experienced Boulderscape artisans hand carved, textured, and stained the shotcrete in the plastic state to replicate the appearance of the approved G8 Hawaiian Lava mockup. The completed system saved the customer hundreds of thousands of dollars over hand set masonry and provided a visually authentic masonry appearance while delivering a durable, low-maintenance, and pedestrian-safe retaining solution appropriate for long-term hillside stabilization in a coastal environment.Boulderscape Finish: G8 Hawaiian Lava           Color Scheme: Dark Earth Blend           Shotcrete Thickness: 1” - 3”                 Average Relief: 2 1/2”                      Retaining Wall System: Sierrascape Gabion System                           Shotcrete Mix: 4,000psi 1. 30% - 40% cheaper than form-liner finishes.  2. Faster to install that form-liner or stone veneer. 3. No repetition in the sculpted face.           4. Use of fly-ash in shotcrete contributes to LEED points.                                   5. All finishes are created by hand-tools.        6. All finishes can be easily customized to fit any project.                                  7. Special admixes were used in the shotcrete to create the consistency needed to create the
