Automated Dynamic Cone Penetrometer (DCP) Testing
Get reliable, high-resolution soil strength data faster and easier with the GeoCone Profiler™ — our automated Dynamic Cone Penetrometer (DCP) system.
Understanding what’s below the surface is key to smarter ground improvement. The GeoCone Profiler™ delivers continuous, precise soil strength readings that help engineers and owners make better decisions on site.
What Is the GeoCone Profiler™?
The GeoCone Profiler™ is an automated version of traditional DCP testing. Instead of manual hammering, it uses a mechanized drop hammer to deliver consistent energy and accurate blow counts at regular depth intervals — producing dependable soil strength profiles you can trust.
How It Works
- Drill a 1.5-inch hole through pavement where needed.
- Insert a standardized cone and rod assembly.
- A 30-kg automated hammer delivers controlled blows at a set height.
- Blow counts are recorded every 10 cm of penetration.
- Results reveal soil strength and weak zones with fine detail.
Why It’s Better
- Deeper, more consistent results — reaches depths that manual methods often can’t.
- High-resolution profiles — readings every 10 cm give you a detailed soil picture.
- Faster and more efficient — automated setup and data collection save time and labor.
- Repeatable performance — uniform energy improves data consistency over manual tests.
- Engineering-ready data — results correlate with standard metrics like SPT N-values for design use.
Applications
GeoCone Profiler™ testing is ideal for:
- Evaluating roadway pavement support
- Foundation and slab-on-grade investigations
- Rail subgrade analysis
- Settlement studies
- Ground improvement design and verification
