DuraStor™ Tanks are prestressed concrete storage tanks reinforced with post-tensioning tendons (governed by AWWA D115 and ACI 350). High strength steel tendons apply compression to the tank floor, walls, and roof to counteract the applied forces and provide residual compression. This method actively reinforces the structure and enhances its watertightness and long-term durability.
Suitable for liquid and granular material storage, DuraStor™ Tanks can be constructed in various shapes with capacity ranges from 250,000 to 50 MG+ to suit project needs.
Compared to other tank alternatives including steel, conventional and AWWA D110—DuraStor™ Tanks offer geometric flexibility, stricter watertightness standards and may offer a significant savings in construction and long-term maintenance investments.
Reinforced with VSL Post-Tensioning Products
DuraStor™ Tanks are reinforced with VSL post-tensioning systems – which have been used as the industry standard for post-tensioning throughout the world. To offer the most durable tank solution on the market, DuraStor™ Tanks are constructed with unbonded post-tensioning in the floors and roofs, while tank walls are constructed with both unbonded and bonded post-tensioning systems.
STRUCTURAL TECHNOLOGIES is the exclusive manufacturer of VSL post-tensioning products and construction systems in the United States.
