TRIAL PITTING
Trial pitting is the cheapest method of shallow soil exploration can be carried out by a variety of methods from hand-dug pits to machine excavated trenches.

Trial pits are especially useful in variable man-made soils for environmental sampling.
Trial pitting is generally carried out to a maximum depth of 2 to 5m with standard excavation plant and, dependent on soil conditions is generally suitable for most low-rise developments.

Trial pit investigations are supervised by experienced engineers with a thorough understanding of geology and soil mechanics.

Additional testing in trial pits can include:-

• Soakaway testing,
• CBR testing
• In-situ strength testing.
