In-situ ground testing
Field tests to investigate ground conditions at selected locations. The method depends on the soil, access and investigation objective.
Select the method for the ground
Discuss vane shear, Mackintosh/JKR probing and permeability testing. Agree the test locations, procedure and interpretation requirements before work.
Earthworks quality checks
For field-density testing and other earthworks quality checks, explore NatTest Lab’s soil and earthworks tests.
Tests in this family
-
Dynamic Cone Penetration (DCP) Test
Dynamic cone penetration testing records penetration per hammer blow. Results support assessment of pavement layers and subgrade; any CBR estimate depends on the correlation used.
-
Mackintosh Probe Test
Mackintosh probing records penetration resistance with depth. Results support preliminary assessment of ground conditions and require site-specific interpretation.
-
Shear Vane Test
Field vane testing measures the torque needed to shear cohesive soil and estimate undrained shear strength. Suitability depends on the soil and test conditions.
