Trial Pits

Trial Pits

 Trial pits are a rapid and cost effective method for allowing assessment of the shallow soil profile and groundwater conditions at a site. Trial pits can be excavated by hand digging techniques for the purpose of confirming shallow foundation construction of existing buildings, for locating existing utilities or for sampling the near surface soils. Machine excavated trial pits can be utilised for investigation of the shallow soil profile down to depths of approximately 4.00m (with standard excavation plant). Soil samples can be obtained from the trial pits for subsequent geotechnical and contamination laboratory testing (all in our in-house *MCERTS and *UKAS accredited testing laboratory).
