Unparalleled Durability & Reliability

Our unique design features provide unmatched durability and service.

Flexible Floor Wall Connections: Each tank is constructed so that the floor and walls are structurally independent. This allows the wall to expand and contract without placing excessive bending stresses on the wall or floor.

External Prestressing: The tank walls are placed into compression by circumferential prestressing. Every prestress wire or strand is fully encased in shotcrete to provide long-term corrosion protection. This ensures the tank walls will remain in permanent compression, eliminating shrinkage cracks, stress cracks, seepage, and deterioration.
