Cast-in-Place
Typical Applications
With rebar couplers, columns can be cast to their full height, resulting in a faster construction cycle.
Without couplers, a lap length is required for continuation bar connections. The formwork must be custom-made with holes for the rebars, which often leads to concrete leakage.
Without couplers, the core wall can only be cast floor by floor, along with the slab. Couplers simplify the construction process!
Couplers not only eliminate unnecessary rebar costs and reduce rebar wastage by up to 10%, but they also reduce rebar congestion at lap areas.
Couplers help maintain the load path and structural integrity, while also reducing the cost associated with the overlap length of rebar.
Bending and unbending the bars requires more tools and may increase the risk of bar breakage. Couplers make the installation of continuation bars easier.
To connect pre-fabricated cages, caging couplers offer a more flexible and faster method than traditional bar welding.
The use of couplers results in a faster construction cycle and more efficient rebar connections.
When space is limited on the project site for installing a tower crane for high-rise construction, an opening in the floor slabs is required. By leaving bridging couplers inside the slabs, reconnection becomes easier and more time-efficient.
The absence of protruding bars on the main pier allows for the use of climbing or slipform systems, enabling faster construction cycles.

Anchoring alternative to hook bars and long development length.
Headed Bars are a simple and effective alternative to hooks and long development lengths.
A compact disc is mounted onto the reinforcement bar end. The assembly of the rebar and the anchor provides an anchorage superior to long straight or bent reinforcement bars while being simpler and faster to install.
Headed Bars contribute to reducing rebar congestion in the heavily reinforced area, which ultimately eases the compaction process and result in better concrete quality in key areas of the structure.
GFRP rebar for permanent applications.
Corrosion-free alternative to steel rebar, GFRP rebar allow contractors to substitute steel rebar with composite non-corrosive and non-metallic reinforcement. ASTEC Glass Rebar can be used for both new construction or as a strengthening material. ASTEC GFRP rebar solutions offer very high tensile performances for a light weight: up to 8 times the performance / weight ratio of steel.
Since 1996, Dextra has established new standards becoming the worldwide reference in FRP rebar manufacturing, made by pultrusion. Precursor of this technology, we have successfully supplied thousands of projects all around the world.
For more information, please refer to our technical documentation. Dextra design team is also available to assist with the design and optimization of your GFRP rebar applications.
