This project required a combination of underpinning a new home foundation with micropiles, while also stabilizing a vertical boulder face using tiebacks, Titan micropiles, gunite & steel. The resulting reinforced boulder face then provided the foundation for a hillside infinity edge swimming pool overlooking Diamond Head Beach. Objectives: to secure the existing undermined rock outcropping; stabilize the base level for the pool and new home while protecting nesting Shearwater seabird population during the construction process.
