What standards does your soil mechanics laboratory follow?

Our laboratory operates in accordance with British Standards (BS 1377) and Eurocode 7. All testing procedures are accredited under ISO 17025, ensuring compliance with UK regulatory requirements for geotechnical investigations.

How long does a typical soil testing program take?

Standard classification tests such as granulometry and Atterberg limits are completed within 5–7 working days. Advanced triaxial and consolidation tests may require 2–4 weeks, depending on the number of samples and drainage conditions.

Do you provide services for small-scale projects?

Yes, our firm supports projects of all sizes, from residential extensions to major infrastructure. We offer flexible sampling kits and remote consultation to accommodate smaller budgets while maintaining full technical rigor.
