Interlocking block is an economical, environment-friendly and effective solution to erosion problems. The unique octagon-shaped blocks can be used with coco fiber mat to protect against soil erosion. The open areas in the system
allow for relief of hydraulic pressures to ensure system integrity throughout the installation. It allows flexibility to adjust to changing soil conditions while managing the lateral stability of the system. This is normally
used in stream banks with velocities which may exceed 3 meters per second.
