What Is The Clegg Hammer Test?
Clegg Hammer Testing is a tried and tested non-destructive method to record surface hardness and compaction and provides a straightforward means for measuring and controlling soil strength and consolidation levels. It is used for verifying the average compaction over a large area of ground and identifying poorly compacted areas and inadequately rolled material.
What Does The Test Involve?
Using a Clegg impact soil tester, a compact and reliable instrument, the test involves dropping a weighted hammer from a fixed height and recording the Clegg Impact Value (CIV), a numerical value of the surface’s strength and density. The CIV tells you if a surface is too soft, too hard or optimally compacted and meets the specific requirements of its intended use.
A successful test will yield consistent CIv values across multiple points of the surface being tested. If results are consistent and within the desired readout range, it confirms uniform compaction and hardness across the site area.
The Process
Not sure what to expect from this test? Our process is simple and is designed to give you precise and consistent results.
Here’s how it works:
Initial Consultation
We discuss your project requirements, the surface type and the standards or regulations that need to be met.
On-Site Testing
We will arrive at your location with our Clegg impact hammer ready to perform the test on an agreed date. We drop the hammer weight from a fixed height (450mm) onto the surface and the accelerometer in the hammer records the CIV from the backlit readout unit which is held during the test.
Multiple Test Points
To ensure accuracy we test multiple random areas across the compacted surface. This gives us a complete picture of the entire site and helps us collect more reliable results.
Reporting
Once testing is complete we provide a detailed report with the CIV results and any recommendations for repair or improvement.
Ongoing Monitoring
For clients who need regular testing, we offer ongoing monitoring to track changes in the surface over time where necessary.
Why Surface Testing Matters
Surface compaction and hardness affect the safety, performance and longevity of your project. Without testing your compacted surface you may experience premature wear, structural failure or safety hazards.
By using CBR Testing UK for your site testing you can:
- Improve Safety: Prevent injuries by ensuring surfaces are compacted to their intended use.
- Ensure Durability: Compacted surfaces are more resistant to weather, heavy traffic and wear and tear, extending their life and reducing maintenance costs.
- Comply With Regulation: Meet industry-specific standards and local regulations to avoid any fines or penalties.
- Save Time and Money: Identify issues early and you can fix them before they become expensive repairs or cause project delays.
