Internal Post-Tensioning for Bridges

Stronger Bridges. Longer Service Life. Greater Value.

The internal post-tensioning systems from VSL are designed to help owners achieve safer, longer lasting, and more cost-efficient bridge structures.

By applying controlled compressive force to concrete, the system increases load capacity, minimizes cracking, and improves overall structural performance. Using advanced multistrand tendon technology, multiple high-strength steel strands work together to deliver reliable strength where it matters most.

In fully bonded configurations, each strand is permanently bonded to the concrete, providing:

Enhanced structural safety
Improved load distribution
Greater redundancy
Long-term durability

The result is a bridge structure built for reliability, resilience, and extended service life.

Every bridge project presents unique challenges. VSL systems are engineered to adapt to a wide range of structural demands, including:

Cast-in-place and precast bridge girders
Segmental bridge construction
Box girders and deck slabs
Stay cable anchorage zones
Complex geometries and demanding environments

Flexible tendon profiles—straight, curved, or inclined—allow seamless integration into modern bridge designs.

From design to installation, HET provides comprehensive technical support to ensure project success.

Installation in compliance with EN 445, 446, 447 and ISO 14824
Project-specific grout solutions developed in-house
Certified installation teams trained through VSL Academy

This integrated approach ensures consistent quality, regulatory compliance, and dependable long-term performance.
