What is structural bonding?
Structural bonding uses compatible resin systems to create force-transferring connections between prepared concrete, steel, precast elements or repair materials.
When is it appropriate?
It may be appropriate for bonded plates, composite repairs, precast connections and new-to-existing concrete interfaces when engineering design defines the load path.
Typical applications
- Steel plate bonding
- Concrete-to-concrete bonding
- Precast element connections
- Composite repair interfaces
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
Typical materials include structural epoxy adhesives, primers, thixotropic bonding pastes, leveling compounds and mechanically anchored details where the design requires them.
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 may be appropriate for bonded plates, composite repairs, precast connections and new-to-existing concrete interfaces when engineering design defines the load path.
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.
