Cone Penetration Testing (CPT)

CPT Plot Soil Classification
CPT Cone

Cone Penetration Testing (CPT) is a cutting-edge geotechnical technique used for detailed subsurface soil analysis. By pushing a cone-shaped penetrometer into the ground, we obtain continuous, real-time data on soil resistance, layering, and other critical geotechnical characteristics. This approach eliminates the need for traditional boreholes while providing highly precise information about the soil's composition and behavior.

CPT is a fast, reliable, and cost-efficient solution for evaluating soil properties, making it a preferred method for site investigations, foundation planning, and slope stability studies. At Helix Geotechnical, we rely on advanced CPT tools to deliver high-quality data that empowers better decision-making throughout your project’s lifecycle.

​

Why Choose CPT?

​

  • Enhanced Soil Data Accuracy: CPT yields precise measurements of soil properties, such as undrained shear strength, surpassing the accuracy of Standard Penetration Testing (SPT). This level of detail allows for optimized designs and potential savings on construction costs. For instance, refined soil data might reduce pile depths, resulting in material and labor cost reductions.

​

  • Continuous Subsurface Profiles: Unlike traditional methods, CPT provides uninterrupted, high-resolution profiles of soil conditions for more granular analysis.

​

  • Minimal Site Impact: This non-invasive method minimizes site disturbance, which is particularly beneficial for environmentally sensitive locations.

​

  • Instant Results: Real-time data from CPT allows for faster analysis and quicker adjustments to designs during the investigation phase.

​

  • Elimination of Lab Testing: CPT directly measures soil properties in the field, reducing the need for time-consuming laboratory testing.

​

  • Accurate Stratigraphy: CPT delivers reliable insights into soil layering, groundwater conditions, and other essential subsurface features.

​

By incorporating CPT into our geotechnical investigations, we ensure accurate, actionable results that support the success of your project.
