Unbonded Internal Post-Tensioning
Bridge maintenance and inspection is made easy with DYWIDAG unbonded internal post-tensioning.
DYWIDAG unbonded internal post-tensioning systems are strong, reliable, and corrosion-proof. Systems can use mono-strand tendons, wire tendons, strand tendons, and DYWIDAG Threadbars™.
Unbonded internal post-tensioning systems are used as
Mono-strand tendons: Bundled, greased, and PE-sheathed mono-strand tendons are typically applied in the construction of buildings—and used in the transversal post-tensioning of bridges
Internal wire tendons: Typical applications for internal wire tendons include bridges and other civil structures that consist of solid cross-sections, or slabs where there is a need to check the stressing level at a later stage
Unbonded strand tendons: Typical applications for unbonded strand tendons include bridges and civil structures.
DYWIDAG Threadbar™: Unbonded internal bar post-tensioning systems are used in projects where infrastructure needs strengthening and repair. Typical applications include the connection between precast members, the fixation or tieback anchorages of steel structures—and transversal post-tensioning.
