Stone Strong Systems worked with Indemic to develop a comprehensive system for creating large blocks for retaining walls in civil construction projects. The system was designed from scratch by Indemic, working closely with the team and Stone Strong, and relied on the extensive use of 3D printing to validate the production process throughout, derisking the entire project and ensuring a robust final outcome. The final components of the system are a range of modular, interchangable parts which are put into large concrete block forming molds, allowing the insertion of pins and anchoring straps that provide the bulk of the retention in a given wall. We provided a full service to Stone Stong, including concept development, engineering, prototyping and testing, CNC machining and tool design, as well as technical illustrations for patent applications.
