Concrete underground storage
Our concrete cisterns are delivered from various factories to your construction site by the shortest route. The heavy cisterns can usually be placed directly into the excavation pit using the truck crane. Our cisterns are suitable for use as rainwater storage tanks, retention cisterns, grey water storage tanks, sedimentation or filter shafts, throttle shafts or also for fire water storage. All tanks are monolithic in their basic design, i.e. made of one piece and therefore also permanently absolutely watertight. They can be adapted modularly. Concrete cisterns are buoyancy-proof with a suitable structure and, depending on the design and cover, can withstand loads of up to SLW60.
