Post tensioning
Thanks to its experienced team of engineers and technicians, TENSA is able to guarantee the highest and worldwide accepted quality standards to every step of the post tensioning process, from the design, to production and on-site installation.
Key advantages
- Highly efficient structural reinforcement system
- Applied in all types of construction
- Higher concrete strength and performance
- Increase of spans' length and design solutions
Systems available
The live anchorage MTAI is the most used and widely spread type of anchorage, whose compact geometry and reduced deviation angle provides a competitive advantage in all project applications, combined with high performance standards and ease of installation. It can be also used in the unbonded MTAIU version, where single sheathed strands are used.
Request informationIt is a non-accessible (dead) anchorage which is used when accessibility during the stressing phases is not allowed. In such a case strands are placed before pouring the concrete of the structure.
Request informationMTG system is the type of anchorage suitable for the coupling of tendons. It is fully integrated with the MTAI system and allows installation of a secondary tendon after the primary one has been completely installed.
Request informationMTAID anchorage for electrically insulated post tensioning is designed to meet the demand for a total and permanent protection of post tensioning tendons from corrosive agents.
Request informationThis anchorage has the great advantage of allowing the adjustment to force at any time, depending on the structure’s behaviour and the project’s construction requirements. It also gives the possibility of monitoring loads, especially in the first period after the installation of cables, when either the strands relaxation or the viscous effects of concrete can affect the acting forces.
Request informationThe new improved system for thin slabs post tensioning is the PTSE, whose compact size is the best performing in the market. Range is from 2 up to 5 strands and can be used as a bonded system with plastic / metal ducts or unbonded with plastic coated strands.
Request informationBonded post tensioning of slabs or thin walls can be performed with the use of flat anchorages PTS, whose range is from 2 up to 5 strands, whose special shape requires reduced space for installation. It can be used both with corrugated metal sheath and plastic ducts.
Request informationSpecial rectangular anchorages are used for ring and intermediate post tensioning: these anchorages also use a special deviator for tensioning with mono-strand jacks.
Request informationSingle strand CU couplers are used to connect tendons built in different stages. Connection is made with single strand CU couplers, to be placed in different layers enabling a compact shape.
Request informationIt is used as a dead end anchorage, done by creating a bulb end on each of the strands composing the tendon.
Request informationThis anchorage can be used in external tendons and comes in different versions, such as: a) fully dismountable (MTAIE); b) restressable (MTAIER); c) not exchangeable (MTAIEX).
Request informationThis anchorage is made of a single cast-iron piece which transfers the load from the tensile element to the concrete and hosts the wedge that grips the strand. It is available either in the unbonded version 1C15UL or in the bonded 1C15BL, both complete with covering caps.
Request informationIt is used where anchorage is not accessible for stressing operations. It can be provided both in the unbonded version 1C15UD or in the bonded 1C15BD version, complete with their relevant wedge spring and fixing cap.
Request informationThis system allows direct mechanical coupling of tendons that have been placed during different construction phases.
Request informationTENSA bars have continuous thread for post tensioning applications in buildings, roads, bridges and viaducts, tunnels and mine shafts. These systems can be provided in diameters varying from 12 to 75 mm, and are used worldwide in post tensioning and in pre-tensioning systems applications.
