Bonded Post-Tension System
Bonded post-tension is a high-performance structural system where tendons are placed inside ducts (gainés) and stressed after the concrete has cured.
After stressing, the ducts are grouted, creating full bonding between the tendon and the concrete structure.
This bonding ensures that the steel and concrete work together as one unified structural system.
Types of Bonded Systems
Corrugated Plastic Duct System
The tendon is placed inside a corrugated plastic duct and grouted after stressing to ensure full bonding and corrosion protection.
Corrugated galvanized Duct System
Uses corrugated galvanized steel ducts for enhanced mechanical resistance. After stressing, the ducts are grouted to create full structural bonding.
