Rockfall Protection and Rockfall Barriers

Rockfalls are a real threat, especially in areas with slopes and walls. Where conventional structures do not assure safety and give way, we at Ocean Global have solutions to mitigate rockfall hazards. Our rockfall protection products (made of high tensile steel wire) withstand low to high impact and are your ideal choice as barriers.

What are Rockfall Protection & Rockfall Barriers?

Active or passive rockfall protection is available. The primary purpose of rockfall protection is to prevent and regulate the fall of boulders and debris. These days, there are a variety of items that can be employed as rockfall protection systems. They’re common in new construction and regions where slopes haven’t been entirely stabilized.

Rockfall protection is an imperfect science that necessitates specialized knowledge and installation processes. Due to the unique behavior of rocks and soil stabilization methods, there are no genuine rules of thumb for implementing rockfall protection systems.

When the source areas are too vast for meshing alone, and some residual risk remains after substantial at-source treatment, a reinforced soil embankment/bund can be built at the slope’s toe as a passive protective structure. They’re usually built over flat or gentle slope profiles, and they’re designed as the last line of defense, with clearance/removal of intercepted material on the up slope side in mind. Because of the ductile nature of the reinforced soil embankments, they absorb rockfall impacts without collapsing, requiring minimal maintenance.

Rockfall Protection Scenario

When there is a serious danger of falling rocks, active mitigation is required. The rockfall protection systems that are created must be able to absorb the shock of the falling rock. It must also be able to contain it in a way that minimizes hazard and provides protection for persons and property.

When the scenario is meant as a preventive method of controlling rockfalls, passive mitigation is required. This strategy is typically employed in locations where the slopes are not fragmented or where slope stabilization measures have already been implemented.

Where are Rockfall Protection & Rockfall Barriers Used?

When the source areas are too vast for meshing alone, and some residual risk remains after substantial at-source treatment, a reinforced soil embankment/bund can be built at the slope’s toe as a passive protective structure.

Because of the ductile nature of the reinforced soil embankments, they absorb rockfall impacts without collapsing, requiring minimal maintenance.

Engineered and non-engineered rockfall mitigation techniques can be divided into two categories. Engineered measures, including source stabilization, works, protection works, and avoidance measures, are actions that either limit the occurrence of rockfalls or lessen their impacts. Warning signs and monitoring programs are examples of non-engineered measures that do not directly alter the rockfall process.
