  • Patent number: 10344444
    Abstract: An edge protection safety bund system (10) for use in connection with a rock bund made of rock fill. The edge protection safety bund system (10) comprises a bund module (12) having a barrier wall (14) and a base plate (16). The bund module (12) is preferably one of a plurality of bund modules (12) arranged side by side to form an extended barrier wall (14). The barrier wall (14) of each module (12) extends substantially perpendicularly upwards from the base plate (16), and a support web (18) extends at an angle from a rear face of the barrier wall (14) to an upper surface of the base plate (16). In use, when rock fill is dumped onto the rear of the bund modules (12), and allowed to flow back to its natural angle of repose behind the barrier walls (14), it creates a rock bund (20) with a front face formed by the extended barrier wall (14).
