Project Description

Various types of debris flow, particularly rockfall, avalanche, landslides and flood debris are all common natural hazards. When these events occur at locations where no passive control measures have been taken, the damage can be catastrophic and become dangerously disruptive to transportation activity, industrial operations and housing centers.

While Terre Armee is renowned not only for reinforcing and stabilizing inhabitable earth formations, our expert staff also have expertise in delivering solutions that control, mitigate and protect against rockfall and debris flow through the use of engineered barriers and nets.


The two main types of protective debris flow barriers from Terre Armee include :

Reinforced Earth® MSE barrier bunds

These robust yet narrowly placed back-to-back MSE barriers are capable of withstanding extraordinary, record-breaking impact loads and debris volume assault while remaining intact while deflecting, separating and diverting high-impact debris flows.

These structures are easily installed, reparable from impact, and are easily enlarged or strengthened as needed. MSE barriers are constructed using a decisive choice of facing materials, soil reinforcements and backfill material. Facing materials may consist of precast concrete panels, wire mesh facing, or metallic panels. Soil reinforcements may consist of either geosynthetic strips or grids, or metallic soil strips. The requirements for backfill types used to construct MSE barriers is also flexible depending on site-specific conditions and service life requirements.

Debris flow catchment barriers

These barriers are composed of flexible high tensile steel mesh nets, whereby the mesh facing base support is either installed securely fixed to the ground surface or is flexibly hinged for elastic, controlled catchment of debris. Mounting and stabilization of the flexible mesh barriers is accomplished with engineered soil-structure techniques using anchoring nails or anchors as prescribed in our optimized design-supply approach for your specific project.

While the MSE barrier solutions provide owners and engineers with passive measures for controlling the damaging effects of intermittent or occuring rockfall and debris flow, our protective net solutions provide owners and engineers with active measures to stabilize rock slopes and prevent the mobilization of debris at the source.
