Trial Pit excavations determine the soil/strata profile, typically up to 4.5m depth, and allow for bulk soil sampling and testing.
Trial Pitting is a suitable site investigation technique for most low-rise developments. Trial Pit excavation techniques can vary from hand dug to machine excavated pits depending on ground conditions.
Trial Pitting can be used as a cost-effective, quick method for determining a basic understanding of the ground conditions / soil profile across a site. It is also useful to supplement other site investigation techniques running concurrently.
All Trial Pit operations are supervised by a qualified Geotechnical Engineer. The engineer will produce a detailed field log of the pit dimensions, soil strata description, any groundwater encountered etc.
Multiple testing techniques can be carried out in Trial Pits including, CBR Testing, infiltration / soakaway testing and in-situ strength testing.
Our services include provision of a full report where we supply a detailed log of each Pit drawn-up in accordance with the Client’s requirements using AGS compatible software such as HoleBASE SI.
All fieldwork carried out in accordance with the relevant British Standards: BS 5930
