 CornerStone® Positive is designed for special project situations that demand retaining walls with exceptional strength such as highway and railway embankments, critical water applications and projects in regions where earthquakes are prevalent.
CornerStone® Positive is available in two versions, CornerStone® Positive 100 and CornerStone® Positive 200.
Both CornerStone® Positive™ 100 and 200 feature a unique geosynthetic positive connecting system that connects units both horizontally and vertically at every reinforcement layer. Units at the geosynthetic layers are connected not only side by side, but also vertically, giving the wall superior positive structural strength. The geosynthetic is wrapped around the connector bar and wedged into the pre-formed grooves in the units above. This creates a continuous geosynthetic positive connection with units above and below the reinforcement layer along the entire length of the wall.
Each positive connector wrapped with geosynthetic interacts with three units creating a unique triangle interlock which significantly increases the connection pullout strength of the geosynthetics and gives the wall incredible structural strength.
Due to it's superior connection capabilities CornerStone® Positive may reduce the geosynthetic strength and number of layers required in the wall, saving the installer time and money. The CornerStone® Positive connectors are only required on courses where geosynthetics are used.
The hollow core, CornerStone® Positive units have been used to create a wide range of attractive, sound and environmentally friendly walls ranging from residential landscaping walls to large commercial projects.
The system uses three basic components (unit, cap and corner) ranging from 65 to 110 pounds. No special equipment is required for installation. These lightweight, hollow core units are much easier to handle than comparable solid units.
The units typically have a random split face that resembles weathered rock. 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.
