Soil needle Penetration

The soil needle penetration test, also known as the cone penetrometer test (CPT), is a simple and rapid in-situ testing method used to determine the consistency and compaction of fine-grained soils. It involves driving a needle or cone into the soil and measuring the resistance to penetration. This test is particularly useful for assessing the strength and workability of soil in the field, providing valuable data for geotechnical engineering and construction projects.

Applications:

• Site investigation for foundation design
• Quality control of compacted soil layers
• Assessment of soil consistency and moisture content
• Evaluation of soil strength for earthworks and embankments
