Ground investigation and land survey
Site data for safer foundations and better design: CPT, boreholes, in-situ testing, survey and monitoring, with soil testing at NatTest Lab.

How it works
From site to report
- 1
Brief
Your site, the structure and what the design needs to know.
- 2
Plan
Test locations, methods and the reporting you need.
- 3
Fieldwork
Testing, drilling and sampling on site by our field team.
- 4
Report
Logs, plots and test results for your engineer.

NatTest Lab
From field to laboratory
Samples from your boreholes go to NatTest Lab for classification, strength, compaction and consolidation testing, so the field data and lab results come from one team.
- Classification and Atterberg limits
- Particle size and hydrometer
- Compaction and CBR
- Shear strength and triaxial
