Strengthening with Post-Tensioning

Post-Tensioning: Enhancing Structural Load Capacity and Performance

Post-tensioning consists of high-strength steel reinforcement that connects to the structure at the anchor points. Ideal for enhancing load capacity, addressing deflection issues, and preventing excessive cracking, these systems offer tailored levels of capacity and serviceability improvement.

Solution Use Cases

Our customizable strengthening solutions can be used for these various requirements.

Change in Code
Seismic Upgrade
Increased Loads
Missing or Misplaced Reinforcement
Deterioration
Low Concrete Strength

External Post-Tensioning

Tendons are installed outside the structural element but may be placed in grouted ducts to improve durability and/or fire resistance.

Internal Post-Tensioning

Installed within a Tstrata Enlargement System or may be installed into an existing member through core drilling or other methods. These systems utilize the structural element itself, or the new enlargement, to provide required durability and fire protection.

Post-Tensioning Products & Systems

Tstrata is the exclusive manufacturer of VSL post-tensioning and construction systems in the United States. VSL systems have a well-earned reputation for their quality, reliability, and durability – and have been used throughout the world since 1956 to build, repair, and strengthen buildings, tanks, bridges, and special structures.

The manufacturing facilities in the United States are certified by PTI’s Plant Certification Program to ensure the highest quality fabrication of materials.

Monostrand Systems

We offer a variety of anchorages and custom-made post-tensioning components that can be utilized for a wide range of strength and protection requirements.

Multistrand Systems

Our multistrand systems and anchors can be designed to hold up to 55 strands encased in duct. The duct may be grouted for additional protection.

VStrand™ Heat Resistant Tendon

Our innovative heat-resistant tendons have been developed to mitigate the detrimental effects of fire on the strength of the prestressing steel.

Threaded Bars

Threaded bar systems are high-tensile steel bars that can be used for post-tensioning and strengthening applications.
