TYPES OF SOIL TEST
IN-SITU TESTING
TRIAL PITTING
DYNAMICS PROBE TEST
BOREHOLES
IN-SITU TESTING
In-situ testing techniques including Standard Penetration Testing, Permeability Testing, Borehole Vane Testing, Pressure meter Testing and Packer Testing can all be carried out in the boreholes in order to provide information for geotechnical design. Disturbed and undisturbed samples are retrieved from the boreholes for inspection and logging by engineers and subsequent testing in our laboratories.
TRIAL PITTING
Trial pitting can be carried out by a variety of methods from hand dug pits to machine excavated trenches. Trial pitting is generally carried out to a maximum depth of 4.5m with standard excavation plant and, depending on soil conditions, is generally suitable for most low rise developments. All trial pit investigations are supervised by experienced engineers with a thorough understanding of geology and soil mechanics.

DYNAMICS PROBE TEST
Cone Penetration Test
To carried out the cone penetration test is pushed into a soil deposit while various measured parameters are recorded. The test is similar to the Dutch Deep sounding (or piezocone test) with the addition of a cone penetration element in the probe to measure water pressure. The test is also known as pore pressure sounding or CPTU.

Mackintosh/JKR Probe Test
This is a dynamic penetrometer test used to check the consistency of the subsoil. Mackintosh Probe which has 30° cone penetrometer while JKR Probes has 60° cone penetrometer. This is a light dynamic test and the cone is driven directly into the soil by driving a hammer 5 kg. Weight dropping through a free height of 280mm. The probe is unable to penetrate into medium strength soil and gravelly ground.
BOREHOLES
A borehole is used to determine the nature of the ground (usually below 6m depth) in a qualitative manner and then recover
