Post tensioning systems are advanced prestressing solutions used to enhance the strength, load capacity, and durability of concrete structures. Instead of relying solely on conventional reinforcement, post tensioning actively compresses the concrete after it has gained sufficient strength, significantly improving structural performance.
JK Prestressing supplies complete post tensioning systems engineered for precision, reliability, and long-term durability in demanding construction environments.
A post tensioning system uses high-strength steel tendons placed inside ducts within concrete. After the concrete cures, the tendons are tensioned using hydraulic jacks and anchored in place, creating compressive force that counteracts tensile stresses.
This results in:
Higher load-bearing capacity
Reduced cracks and deflection
Longer spans with thinner slabs
Lower overall material consumption
Enhanced durability and structural life
High tensile prestressing strands
Anchorage systems and wedges
Sheathing ducts (HDPE / GI)
Bearing plates
Grouting materials and accessories
Hydraulic stressing equipment
Ideal for large span slabs and beams
Faster construction cycles
Cost-efficient structural design
Improved seismic performance
Reduced maintenance over time
