What is Geotechnical Testing

Understanding Ground Conditions

Geotechnical testing evaluates the physical and mechanical properties of soils and aggregates to inform design, construction, and asset management. Services include:

  • Site sampling and in-situ testing (CBR, plate bearing, density, permeability)
  • Laboratory analysis (particle size distribution, moisture content, Atterberg limits, compaction, strength)
  • Classification and compliance with BS 1377, BS 3882, and other standards
  • Reporting with clear recommendations for design and construction

Frequently Asked Questions

Q: What is a plate bearing test?

A: A plate bearing test determines the bearing capacity and settlement characteristics of the ground by applying a load to a rigid plate and measuring the resulting settlement. 

Q: What standards do you test to?

A: We comply with BS 1377, BS 3882, and relevant Highways England requirements. Our full UKAS-schedule is available at www.ukas.com. 

Q: How quickly can I get results?

A: Standard turnaround is typically 5–7 working days, with expedited options available.

Q: Can you provide both site and laboratory testing?

A: Yes, we offer a complete service from site sampling to laboratory analysis.
