FAST - PORTABLE - DATA DRIVEN
Clegg Hammer Features: Advanced Soil Compaction and Pavement Strength Testing
Built for engineers, road contractors, construction inspectors, and quality-control professionals. Test more locations, collect field data efficiently, and identify variations in material performance, with a repeatable drop mechanism, GPS-enabled data collection, and the Clegg Control App in one field-ready system.
Rapid Results
Get Clegg Impact Value readings within 2 seconds of a drop.
Portable & Lightweight
Weighs only 4.5kg (10lbs) for easy transport and operator use.
GPS- Enabled Data
Location and timestamp included with every drop.
Digital Reporting
Collect, organize and export data with the Clegg Control App (CSV export for mapping).
THE CLEGG HAMMER ADVANTAGE
Clegg Hammer Features Designed for Real-World Field Testing
The Clegg Hammer combines proven impact testing methodology with modern digital tools to deliver fast, reliable and location tagged results in the field.
Rapid Soil and Pavement Strength Testing
Get instant Clegg Impact Value Readings to access material response and stiffness. Results are typically displayed on the tablet within approximately two seconds of a drop, helping field teams assess more locations during a working day.
Ideal for: Road construction, pavement evaluation, aggregate testing, earthworks, and compaction quality control.
Test More Locations in Less Time
Identify variations across your project with faster, easier tesing.
The advantage: More observations can help engineers and contractors investigate nonuniform areas that a limited sampling program might miss.
Simple, Single-Operator Operation
Designed for one person use, with ergonomic and efficient workflow.
Lightweight and Portable Soil Testing Equipment
The Clegg Hammer weighs 4.5 kg (10 lb), making it practical to carry and position around a range of field environments where larger testing equipment is less convenient.
GPS Mapping and Location-Tagged Results
Capture coordinates and timestamps to visualize testing location results.
Clegg Control App for Digital Data Collection
Record, review and export results with the supplied tablet or your own Android/iOS device.
Repeatable Drop Height with the Integrated Stopper
Integrated stopper ensures consistent testing between operators and locations.
Streamlined, Protected Instrument Design
No exposed wire combined with a rugged build for real world field use.
Secure, Unaltered Field Data
Preserves original readings against in-app results editing for transparency and quality assurance.
Export Data for Mapping and Reporting
CSV exports work with common software for mapping, analysis and project documentation.
Assess Strength, Stiffness, and Compaction Uniformity
Evaluates impact response of soils, aggregates and pavement materials (not a direct density test).
Results Ready for Field Decisions
Make informed decisions on-site without waiting for lab results.
