Post-Tensioning for Storage Tanks & Silos
Concrete reinforcement for safety, watertightness and durability
Post-tensioning is an active structural reinforcement method used in storage tanks and silos to improve safety, durability and watertightness of critical containment structures. In large containment tanks, such as those for Liquid Natural Gas (LNG), post-tensioned concrete ensures resistance to hydraulic pressure and limits cracking under load, providing essential protection even if the primary steel tank containment is compromised.
Why post-tensioning for storage tanks & silos
Post-tensioning compresses the concrete. This supports resistance to leakage and hydraulic pressure.
It improves the concrete’s ability to withstand high internal loads and environmental forces.
Compression limits cracks and slows degradation over time.
Post-tensioning helps tailor reinforcement to project needs and site constraints.
Optimized reinforcement can reduce concrete volume and support construction timelines.
