Repair
Typical Applications
Connection of two rebar which haven’t been previously prepared (not thread)
Where neither bar-end preparation to form threads nor bar rotation is possible
Our Solutions
Bolted coupler without rebar preparation
Unitec® is a bolted splicing system designed for the connection of two rebars that have not been previously prepared (no thread).
Each Unitec coupler features a long hollow body that will bond with rebar. Several screws will lock both bar ends and complete the connection.
Unitec is designed to be operated with a standard impact/pneumatic wrench.
For repair or retrofit works
RepairGrip system is a portable system designed to splice bars in situ. It is a simple and proven method to splice bars that did not have their end shop prepared.
The RepairGrip sleeve is swaged onto the bar ends by a hydraulic tool powered by a separate power unit. The resulting connection guarantees at least 100% of nominal tensile strength on reinforcing bars grade 500 MPa.
RepairGrip splices are butt-to-butt splices that are suitable for both tension and compression applications.
Tunnelling breakthrough made easy with FRP rebar
Maintaining and upgrading essential infrastructure is a main concern in all parts of the world: the need for repair and strengthening may arise from deterioration, changes in use, changes in the relevant design codes, structure defects or seismic conditions.
ASTEC Carbon Rod provides with non-metallic reinforcing bar having high modulus and tensile strengths. It can be used for both new construction and as a strengthening material for the innovative and proven technique known as «Near Surface Mount» (NSM) strengthening. With a proprietary end anchorage, ASTEC Carbon Rod can be used in un-bonded post tension or pre-stressing applications.
