What is post-installed reinforcement?
Post-installed reinforcement connects new reinforcing bars or dowels to existing concrete through designed drilled-hole systems that form part of a verified structural detail.
What it solves
It is used for jackets, enlargements, extensions and retrofit connections when embedment, spacing, edge distance, substrate condition and installation access are defined.
When it may not be suitable
Performance depends on both design and installation. Hole geometry, cleaning, moisture, temperature, bar position, cure time, concrete condition and verification testing may govern.
Typical applications
- Jacketing dowels
- Concrete extensions
- Slab and wall connections
- Added reinforcement details
Execution workflow
- Review assessment and design basis
- Confirm method, access and compatible system
- Prepare substrate and control the work area
- Install or apply under documented procedure
- Inspect, record and hand over
Materials and systems
Systems may include qualified injection resin, specified reinforcing bars, drilling equipment, calibrated hole-cleaning tools, installation accessories and inspection records.
Product families are selected generically at planning stage and specified only after compatibility, performance requirements and site conditions are confirmed.
Quality control approach
Controls are matched to the intervention and may include substrate acceptance, batch and shelf-life checks, mixing records, temperature and moisture readings, installation sequencing, pull-off or proof testing where specified, photographic records and signed inspection points.
Limitations and engineering considerations
What we need before we recommend this method
A photograph can help start the conversation, but it cannot establish a structural diagnosis on its own. Useful inputs include:
- Photographs showing the wider structure and the defect
- Available drawings, reports or previous repair records
- Crack, leakage or deterioration history
- Known movement, loading or change-of-use information
- Access, occupancy and shutdown constraints
- Available substrate tests or condition data
Frequently asked questions
It is used for jackets, enlargements, extensions and retrofit connections when embedment, spacing, edge distance, substrate condition and installation access are defined.
No. Suitability depends on verified condition, engineering requirements, substrate, exposure, access and the intended service life. Project-specific assessment and design may be required.
The project method should define substrate acceptance, material checks, environmental limits, installation records, hold points, inspection and handover documentation appropriate to the system.
