Bonded Slab Post-Tensioning Systems
Featuring the same benefits as bonded multistrand post-tensioning, our bonded slab systems utilize flat ducts to maximize eccentricity of the prestressing and to reinforce slabs as thin as 5″. Bonded slab systems allow for future modifications, such as drilling, coring, and openings. When bonded prestressing steel is cut it behaves similar to rebar in that the loss of force is localized. These systems are used in a variety of applications, including parking deck slabs to enhance long-term durability, transfer slabs, containment structures, and bridge decks.
Design advantages include increased span lengths, thin slabs, and improved load-carrying capacities.
Strands are protected by the grout, duct, and surrounding concrete. Bonded slabs also allow designers to significantly reduce the use of conventional steel reinforcement, particularly at the top of the slab.
Bonded systems offer more flexibility regarding structural modifications such as openings for stairwells, utility access, and future expansion. If a tendon needs to be cut, the loss of tendon force would be localized. The remainder of the tendon would retain its force at the development length away from the failure point and would remain functional.
