PISA® retaining walls are the ideal way to handle grade changes in any landscaping or gardening project as well as increase the amount of useable space for patios, terraces and parking.
PISA® walls are easy to install, require little maintenance and last a lifetime. PISA® walls are environmentally safe, because they are manufactured from natural aggregates and contain no toxic chemicals.PISA® can be used for:
- Straight Walls
- Curved Walls
The PISA® Retaining Wall System utilizes its unit weight and shape to resists lateral earth pressure. The patented offset continuous tongue and groove allows for a solid interlock throughout the wall face, while providing a uniform connection with geogrid.
The PISA® retaining wall system can be used effectively for gravity wall structures up to a maximum of 4 feet. For greater wall heights and applications, PISA® together with a geogrid soil reinforcement is required.
