Stepped gabion weir at Pacific Pines

These hydraulic structures are designed to cope with one-in-one-hundred-year flood events. They must be well engineered and well constructed — especially where gabion and rock-mattress elements are used.

Gabions are eminently suitable for weirs, drop structures, culvert outfalls, and wing walls. They provide a monolithic, yet permeable and flexible, structure that allows pore pressure dissipation.

Concrib gabions also have the ability to handle unexpected differential movements should design parameters be exceeded.

Concrib was able to provide the client a design / construct service to facilitate the construction of this stepped gabion weir built to withstand a Q100 event.
