Area of Application

Rectangular mesh 50/50/3.1 is a single twisted mesh product used for standard strength slope stabilization solutions. Like other rectangular mesh, it conforms to slopes better than hexagonal mesh, yielding maximum surface contact for better control of erosion. Both draped and anchored mesh systems are common applications.

Single Twisted

A single twisted product is the standard mesh type often called chain link. Individual wires are woven together with half a turn to create a rectangular or square opening. The result is a product with high flexibility along the axis of the roll, with no roll memory.

Draped Mesh System

Draped mesh systems allow material behind the mesh to move down slope in a controlled manner. These systems are normally secured along the top of the system with a suspension cable, with few or no anchors below.

Anchored Mesh System

To prevent the movement of small material down a slope, the mesh may be pinned using a matrix of soil or rock anchors, possible with the combination of steel ropes and anchor plates. Such systems are termed slope retention or anchored mesh systems. The anchor spacing, depth and type must be designed by a geotechnical engineer to properly accommodate the expected forces and to reduce maintenance.

Ice Mesh System

An interesting application of slope mesh is for mitigating falling ice. Mesh is mounted on anchors to avoid surface contact with the slope. As ice accumulates during the winter, it does so behind the protective mesh layer. This protects infrastructure downslope as temperatures warm and ice begins to spall off.
