We are a leading provider of post-tensioning solutions, serving commercial, residential, and infrastructure sectors. With decades of combined experience, our engineers and technicians specialize in the design, supply, and installation of post-tensioned slabs and structural systems.
Our mission is to provide high-performance concrete solutions that reduce construction costs, improve structural efficiency, and ensure long-term durability.
Post-tensioning is the smart, modern solution for creating durable, efficient, and cost-effective concrete structures. Our expert post-tensioning services are tailored to optimize structural performance, reduce construction material, and enable flexible architectural designs — from residential buildings to large-scale infrastructure.
Advantages of Post–Tensioned Slab System
Advantages of Post–Tensioned Slab system
Architectural aspect
Space can be easily allocated for the service purpose. Wall or walls are not required to be on a flat surface, It will not obstruct pipeline system or work system.
Reduce the height between the floor and the total height of the building, making the height of the building not exceed legal requirement.
Can design buildings with longer interval between each pillar, making the space inside the building spacious and beautiful.
Can adjust utility space interior living space for any occasion.
Structural aspect
Post-Tensioned Flat Slab system provides flat and thin floor. The overall weight is less than reinforced concrete floor. As a result, it is possible to reduce the construction cost of foundation work, save the structural wood and construction overhead.
Can be designed to have less deflection of the floor, compared to reinforced concrete Flat Slab.
Fire resistance is taken into account in the designing of Post-Tensioned Flat Slab by selecting number of hours which will resist to fire, according to the instruction of Post Tensioning Institute (PTI).
Can better withstand earthquakes, resistant to cracking, the structure is tough.
Valuable aspect
Construction cost per square meter is cheaper than reinforced concrete floor. For areas with a long pillar interval over 6 meters and large building.
Save construction time. Construction period takes 7–10 days for one floor.
More number of floor at the same height, extending more utility space, can support general force and earthquake less than that of the same number of floor.
Unbonded Post-Tensioning Services
Unbonded post-tensioning is a method of concrete reinforcement where high-strength steel tendons are coated in grease and encased in a plastic sheathing. These tendons are not bonded to the surrounding concrete but are anchored at each end, allowing for post-tensioning after the concrete has cured.
At Streben, we specialize in the design, supply, and installation of unbonded post-tensioning systems for residential, commercial, and infrastructure projects. With a focus on quality, efficiency, and safety, our team delivers high-performance concrete solutions that reduce costs and improve structural lifespan.
Backed by experienced engineers and PTI-compliant practices, we support clients across all phases of construction — from initial planning and design to on-site execution and quality assurance.
Our Unbonded Post-Tensioning Services Include:
Structural Design & Consulting
Customized design for unbonded PT slabs, beams, and structural elements using advanced software and standards.
Supply of Unbonded Tendons & Anchoring Systems We provide high-strength, greased, and sheathed tendons, anchorage hardware, and accessories that meet ASTM and PTI standards.
On-Site Installation & Stressing Professional laying, stressing, and cutting of tendons performed by certified technicians using modern equipment.
Quality Assurance & Elongation Reports We offer complete QA documentation, elongation verification, and compliance reporting.
Post-Construction Support & Maintenance Services for tendon inspection, maintenance, and long-term performance monitoring.
Bonded Post-Tensioning Services
Bonded post-tensioning is a method of concrete reinforcement where high-strength steel tendons are tensioned and then permanently bonded to the concrete using grout. This creates a monolithic structure with excellent durability, crack control, and load distribution.
Bonded systems are widely used in bridges, heavy civil infrastructure, and multi-span buildings where long-term performance and redundancy are critical.
Backed by experienced engineers and PTI-compliant practices, we support clients across all phases of construction — from initial planning and design to on-site execution and quality assurance.
We provide end-to-end bonded PT services for both new construction and retrofitting projects:
Design & Engineering
Supply of Tendons, Ducts & Anchorages
Installation & Tensioning
Grouting & Quality Testing
Inspection & Repair
