Basic Concept
The BULLFLEX® system has been developed as a special supporting member for Underground excavation. It consists of patented textile groutable hoses made of high-strength fabric, which are subsequently filled with cement-bonded construction material, featuring an excellent load-bearing capacity. The BULLFLEX® system is available in different dimensions, allowing an optimum alignment to the excavation or support perimeter. All system components are light-weight and easy to transport and to install. DSI Underground has long-time experience in the application of the BULLFLEX® system which has been successfully used in various projects.Main Advantages
