STRUCTURAL TECHNOLOGIES’
DuraStor™ AWWA D115 Prestressed Concrete Tanks The Most Versatile & Durable Concrete Tank Solution Available STRUCTURAL TECHNOLOGIES’ DuraStor™ Tanks (AWWA D115 Tendon Prestressed Concrete Tanks) offer the benefits of prestressed concrete and the geometric flexibility of conventionally reinforced concrete.
Unlimited Applications – Any Shape, Any Size Whether driven by process or space considerations, DuraStor™ Tanks may be engineered and built into any shape or size, similar to conventionally reinforced tanks.
Applications
Durable & Watertight
• Combined Sewer Overflow Systems
STRUCTURAL TECHNOLOGIES’ DuraStor™ Tanks are ideal for use in water storage and treatment structures – 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 providing crack free concrete, joint free slabs, and no measurable leakage.
Economical – up to 25% Cost Savings
• Water Storage • Water/Wastewater Process & Treatment • Thermal Energy Storage DuraStor™ Tank Features • Watertight – no leakage • Low maintenance
Based on size and other design criteria, DuraStor™ tanks may offer a significant savings in construction and long-term maintenance investments compared to other concrete tank alternatives available. Compared to conventional concrete – DuraStor™ tanks reduce materials, labor, and schedule, saving up to 25% in initial construction investment.
• Joint-free floor & roof
Featuring VSL Post-Tensioning Technology
• Walls may be finished to meet architectural requirements
DuraStor™ Tanks are reinforced with VSL branded products – which have been used as the industry standard for post-tensioning throughout the world.
• Reduced material & labor costs • Enhanced seismic resistance • Built in all weather conditions • Suitable for all types of liquids

Comparing Concrete Tank Types Conventional
AWWA D110
DuraStor™ AWWA D115
Using only conventional rebar reinforcement, these may be designed to any shape or size. Requires joints and have generally higher construction and maintenance costs, as well as increased leakage rates.
Prestressed Tendon Types:
There are several types of D110 tanks, but all have walls that are prestressed with wire or strand covered by sprayed concrete. Similar to conventional tanks, the floor is conventionally reinforced with joints. DuraStor™ tanks utilize prestressed tendons inside cast-in-place concrete to provide a watertight and low-maintenance tank built to any shape or size. Floors and roofs are also prestressed with no joints. A prestressed roof design allows tanks to be buried or carry significant loads efficiently Prestressed tendons have triple corrosion protection compared to other tank types
