Pisa 2

The built-in setback design of Pisa2 automatically forms the correct slope, ensuring a highly stable retaining wall. Utilizing the product's tapered components, the Pisa 2 is perfect for forming curved walls and steps.

Roma Pisa

Split and weathered-looking, Roman Pisa boasts a distressed appearance that gives the impression that it has been around for decades. Admired as much for its versatility, Roman Pisa can be used to form straight or curved walls.


Bold and dramatic, Siena Stone (over 450 lbs ea.) strikes an impressive profile when used for a wall or as treads in large outdoor staircases. An attractive solution for most heavy-duty load-bearing applications.
