SienaStone

SienaStone combines the stability of large modular units with exceptional versatility and flexible design details, making it suitable for residential and commercial applications. Steps, curves, corners and angles can be easily constructed and efficiently erected with only light construction equipment. Its array of engineered units allows for economical single depth walls utilizing 333 or 500 units, or multi depth walls with 925 units, where available space is limited.

SienaStone can be designed/built as a Gravity Wall (up to 4m/13′) as well as an economical geogrid reinforced wall (over 12m/39′). For maximum design efficiency, the system can easily change from a Gravity Wall to a Reinforced Wall at any point along its length without changing the overall appearance.
