A Concrete Rebound Hammer in Canada is a fast, non-destructive way to check surface hardness and estimate compressive strength trends in hardened concrete. Many teams also call it a Schmidt hammer, rebound hammer, or concrete test hammer.
A spring-driven impact produces a rebound number that can be compared across zones, pours, or structures. This supports practical field decisions before moving to higher-resolution methods such as cores or UPV. Qualitest offers analog and digital concrete rebound hammers built for jobsite use and repeatable readings.
Why Teams in Canada use Rebound Hammers
Concrete work in Canada often involves tight schedules, variable curing conditions, and large footprints such as parking garages and bridge decks. A rebound hammer helps screen wide areas quickly without shutting down work.
It supports uniformity checks across slabs, beams, columns, and precast elements. It is also practical for condition checks during renovation, retrofit, and maintenance. Results are immediate, so teams can document findings on-site and plan next steps.
Common Applications
- On-site screening for buildings, bridges, tunnels, and industrial floors
- Quality control to compare uniformity across batches, zones, or repairs
- Condition surveys on existing concrete before drilling, coring, or anchoring
- Preliminary assessment to target locations for cores or ultrasonic testing
- Acceptance checks for precast yards and routine production monitoring
How a Rebound Hammer Works
A spring-loaded mass strikes the concrete surface at a consistent energy. The instrument records the rebound number, which correlates with surface hardness. Multiple readings across a grid help show variation and potential weak areas.
Surface condition affects results, so consistent preparation and technique improve repeatability. For best practice, take several impacts per test area and avoid edges, honeycombing, and obvious defects.
Standards Referenced for Rebound Hammer Testing
Qualitest concrete rebound hammers are aligned with widely used methods for rebound number testing, including:
- ASTM C805 / ASTM C805M
- EN 12504-2
- BS 1881: Part 202
- ISO 1920-7
- JIS A1155
These standards help keep procedures consistent for reporting, quality programs, and comparative evaluations.
