General Information

CornerStone® Positive is a vertical system 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 Walls

Ease of construction

The system uses three basic components block, cap and corner units. Maximum weight of straightface units are 36.4kg each (11 units/m2 face).

No special equipment is required for installation. These lightweight, hollow core units are much easier to handle than comparable solid units.


Stability, strength and safety

CornerStone® Positive™ features 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.


Low cost

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.


Appearance

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. Colours and available faces will depend on your market area.


Adaptability

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.


Design

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.
