Geosynthetic Connecting System
Each cornerstone positive connector is wrapped with geosynthetic, which interacts with three units to create a unique triangle interlock. significantly increasing the connection pullout strength of the geosynthetics and gives the wall incredible structural strength.
Best of all, CornerStone® Positive may reduce the geosynthetic strength and number of layers required in then wall, saving the installer time and money. The CornerStone® Positive connectors are only required on courses where geosynthetics are used.
We’re about creating beautiful things simply, and that means ensuring that our natural surroundings are also cared for. With less concrete required for manufacturing, and more efficiency in transportation, we ensure that we leave a smaller carbon footprint.
Using less concrete, costs significantly drop due to less weight (lowers freight & shipping costs), less required installers, lower development costs, without any loss in structural stability!
Flexible Design & Solutions
The high strength CornerStone® Positive connectors are flexible and easy to install when building concave or convex curved walls.
Whether the design is simple or complex, a CornerStone® Positive wall will retain its strength while flexing under seismic loading or other stress condition. CornerStone® Positive’s durable, high shear strength connectors along with its SecureLugs allow for significant lateral movement without losing the interlock. The tapered sides with its removable wings make it easy to build tight curves and straight walls with complete accuracy.
The unique hollow core design, reduces efflorescence problems & costly pigments. In addition, the weight ranges from approximately 65 – 75 lbs, allowing for minimal manpower and no special equipment to install the product.
With a face that typically resembles weathered rock, the unit shape and size are balanced to provide a natural profile that complements virtually any design or style of construction. Colors and available faces will depend on your market area. Please contact you local producer.
