SonomaStone™
A machine-installed wall with the look of hand-placed units.
The combination of unit-size, design and a patent-pending installation clamp gives you unrivaled installation productivity, making SonomaStone one of the most popular heavy-duty retaining wall systems available today. This system can be designed as a single or multi depth gravity wall, as well as geogrid reinforced, making it ideal for walls up to 9m (30′) or higher.Colors
