What is In-Situ Testing

In-situ testing involves carrying out soil and ground assessments on-site using specialist equipment. Unlike laboratory testing, the results are available immediately, allowing you to make quick and informed decisions about your project.

These tests help identify:

• Soil strength and stability
• Ground bearing capacity
• Permeability and drainage
• Compaction and density


By understanding these factors early, you can avoid costly errors, delays, or safety risks during construction.

Our In-Situ Testing Services

We offer a comprehensive range of in-situ testing methods, tailored to the requirements of your project:

  • Plate bearing tests
    to assess soil load-bearing capacity
  • CBR (California Bearing Ratio) Tests
    ideal for road and pavement design
  • Dynamic probing
    to evaluate soil resistance and consistency
  • Density and compaction testing
    ensuring ground is suitable for building

Our team uses modern equipment and proven techniques to deliver reliable results quickly and efficiently.
