What is concrete repair & rehabilitation?
Concrete rehabilitation removes unsound material, treats contributing causes and rebuilds the section with a compatible repair system designed for the exposure and structural requirement.
When is it appropriate?
It is appropriate for spalling, delamination, reinforcement corrosion, impact damage, voids and localized section loss after the cause and remaining substrate condition have been assessed.
Typical applications
- Columns, beams and slabs
- Facades and balconies
- Industrial concrete
- Bridge and infrastructure elements
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
Generic systems include corrosion-control treatments, bonding primers where required, polymer-modified repair mortars, flowable micro-concretes, crack repair products, curing materials and protective coatings.
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
Frequently asked questions
It is appropriate for spalling, delamination, reinforcement corrosion, impact damage, voids and localized section loss after the cause and remaining substrate condition have been assessed.
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.
