Storage Bunkers and Vaults

The Reinforced Earth® system has become the predominant method of construction for sloped-wall coal and mineral storage facilities worldwide.


These structures are used to regulate the storage and flow of the mineral to meet the requirements of the facility – often a mine site or coal fired power station,


Utilising the Reinforced Earth® method, the structure is built at the required design angle and may use a buttress to the rear of the concrete facing panel to assist with construction stability. Soil reinforcement connected to the back of the panel is backfilled in layers in the traditional way.


Studies have shown that the Reinforced Earth® system offers advantages over alternative construction methods for these structures (such as cast in situ concrete) which range from rapid and faster erection to cost and construction safety. In addition, predictable and economical construction procedures and the ability to withstand and adjust to differential settlement and heavy loading without loss of structural integrity, make Reinforced Earth® a preferred construction methodology.
