Geohazards such as rockfall, landslide and avalanche pose a great threaten to the development of the human environment and the safety and well-being of people. Choosing the right geohazard protection system is of great importance to realize effective geohazard prevention and mitigation.
With over 20 years of geohazard protection system study and production, we know well about the characteristics of geohazard protection systems we produced and corresponding application environments. As a result, we list some factors that affect your geohazard protection system selection to help you choose the right product you need as quickly as possible.
Decide your application environments
Before choosing a geohazard protection system, you must know what kind of geohazard commonly occur in this area. For geohazards that may have sudden high impacts such as rockfall, debris flow or avalanche, ring net system is often an optimal choice. Made of high tensile steel wire and interlinked ring structure enable it withstanding sudden high impact and absorbing maximum energy through deformation, thereby protecting infrastructure and community from damage. For other geohazards that may not produce sudden high impacts such as minor slope landslide, a variety of geohazard protection systems can be recommended, for example, Rockcon® system, reinforced rockcon system and hexagonal netting system.

Decide active or passive protection method
Active and passive protection methods are two kind of geohazard protection methods commonly used. If possible, geohazard protection may adopt a combination of active and passive protection methods, for example, in slope protection applications. The factor decides you choose active or passive protection method depends on whether the area with the real danger of landslide or falling can be secured. If this area can be secured, active protection method is generally adopted to cover this area with wire mesh and fasten the wire mesh with soil nails and spike plates. Besides, it also ensures the deformation and maintenance work to be kept to a minimum. However, if this area cannot be secured, you have to choose passive protection method and consider the large deformation it may cause. In addition, the passive protection method can be only applied to limited areas.

Decide your mesh size
For moderately steep slopes with loose soil or small weathered stones, Rockcon® system or hexagonal netting system with small mesh opening is good enough to provide sufficient static load bearing capacity. However, for steep slopes with large weathered stones, reinforced rockcon system or ring net systems with large mesh opening and high tensile strength is recommended to provide higher static load bearing capacity so as to fasten large falling stones.

Decide one or more geohazard protection system
Generally speaking, geohazard protection system is enough for geohazard prevention and mitigation. However, sometimes, two geohazard protection system often work together to provide better protection. As ring net system and reinforced rockcon system have big mesh opening, they cannot stop the movement of small objects, therefore, they commonly work with Rockcon® system or hexagonal netting system to stop small objects and enhance the overall impact resistance of the system.
