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
