Special Structure & Strengthening Solution

Prestressing is not limited to new bridge construction — it’s also a proven solution for strengthening existing structures, rehabilitating aging infrastructure, and enabling complex architectural designs. Whether you’re extending the life of a deteriorating bridge, reinforcing a storage tank, or building a unique architectural structure, post-tensioning and external prestressing provide efficient, durable, and cost-effective solutions.

✓ Extended service life

✓ Increased load capacity

✓ Minimal disruption to use

✓ Cost-effective rehabilitation

✓ Design flexibility

Applications

1. External Post-Tensioning for Bridge Strengthening

External tendons installed outside the existing concrete section to increase load capacity and extend service life — ideal for aging bridges with increased traffic demands.

2. Storage Tanks & Containment Structures

Circumferential and vertical prestressing for concrete tanks, silos, and containment vessels — ensuring liquid-tight integrity and resisting internal pressure.

3. Nuclear Containment Vessels

High-reliability post-tensioning systems for nuclear power plant containment structures — designed to meet strict safety and regulatory requirements for long-term performance.

4. Offshore & Marine Structures

Corrosion-resistant prestressing systems for offshore platforms, jetties, and marine structures — engineered for harsh environmental conditions and long service life.

5. Architectural & Complex Structures

Post-tensioning enables elegant, slender architectural forms — curved roofs, pedestrian bridges, and complex geometries that would not be feasible with conventional reinforcement.

Key Technical Considerations for Strengthening & Special Structures

Consideration	Recommendation
External tendon routing	Use deviation saddles to achieve required force profile — avoid sharp bends to prevent strand damage
Corrosion protection	Select grouted or greased-and-sheathed system based on exposure conditions — critical for long-term durability
Anchor zone reinforcement	Ensure sufficient reinforcement to handle concentrated anchor forces — use spiral reinforcement and supplementary rebar
Monitoring	Install load cells and monitoring systems for long-term force verification and structural health assessment
Strand seating	Allow for seating losses in design calculations — typically 3–5mm for external tendons
