67 Proven Pull-Out Tests – GroundGrabba Strength Results
When Strength Matters, We've Got the Proof
When your assets are on the line, you need anchors that won’t budge. GroundGrabba has been rigorously tested across a wide variety of terrain types—from beach sand to clay, loam to crushed gravel. Below you'll find verified peak pull-out results from over 67 tests, along with downloadable certification documents and test reports.
Real Data from Real Conditions
These test results are based on field pull-out testing using a hydraulic post puller and crane scale. Each reading reflects the absolute peak load (in kilograms) before failure or extraction.
- Always apply a safety margin.
- Test results vary by soil conditions, moisture, and embedment depth.
- For certification-critical installations, seek engineering sign-off.
