Service Type: Rebar Grouting
Hilti rebar fixing work involves drilling holes, injecting Hilti chemical mortar, and installing rebar for applications like extending, strengthening, or adding components to existing concrete structures. Key details include using the SafeSet system for automatic hole cleaning during drilling, the Hilti Volume Calculator app for accurate mortar dosage, and Hilti's battery-powered dispensers for precise application. Proper installation requires trained personnel to ensure structural integrity, and Hilti offers training and engineering software for design and compliance. Key components and processes
Drilling and cleaning: The process starts with drilling holes. Hilti's SafeSet system uses an SDS drill with a built-in vacuum to automatically clean the hole as it's drilled, which removes the need for manual cleaning.
Chemical mortar injection: After drilling, Hilti chemical mortar is injected into the hole using a battery-operated dispenser to ensure the correct amount of mortar is used.
Rebar installation: The rebar is then installed into the hole, where it chemically bonds with the concrete.
Design and planning:
Hilti offers software like Hilti PROFIS Engineering for calculating post-installed rebar development lengths for various applications, such as end anchorages and splices, according to building codes like EC2 TR023.
The Hilti Volume Calculator app helps determine the correct mortar volume needed for the job.
Training and quality control
Trained personnel: According to European Organization for Technical Assessment (EOTA) standards, post-installed rebar must be installed by trained and qualified personnel to avoid structural damage and potential liabilities.
Hilti rebar installation training: Hilti provides both theoretical and hands-on training, which can be customized for specific job sites or held at Hilti locations.
Onsite testing: For base materials with unknown capacity or old/damaged concrete, Hilti offers onsite testing to determine design resistance and ensure the correct fastening system is used. This can be a destructive pull-out test or a non-destructive proof load test.
Key applications
End Anchorages: Connecting new concrete elements perpendicularly to existing ones, like beam-to-column or slab-to-wall connections.
Splices: Extending existing concrete elements parallel to each other by overlapping new bars with existing ones, such as in beam or column extensions.
Overlays: Adding a new layer to an existing member to increase its thickness, for example, in beam or column jacketing.
