Terragen ointment
The benefits of this technique are as follows:. Withdrawing centre bit and plug allows access down the stem for sampling and/or installing monitoring standpipes.
Uses a continuous flight auger with hollow central shaft.

Highly portable and useful for progressing shallow exploratory holes across sites with poor access.Allows assessment of immediate hazards.Ī range of augers for different soil types, conditions and sampling requirements, the benefits of which are as follows:.Quick method of delineation and monitoring of near surface soil vapour concentrations.Inexpensive method of testing for the presence of soil vapours.Disposable tubing runs down the centre of the rod which connects to monitoring/sampling equipment, the benefits of which are as follows:. Can be used for integrated contamination and geotechnical investigations.Ī narrow diameter hollow rod is driven to form a hole.Applicable to a wide range of ground conditions.Easy to obtain discrete samples (where entry is appropriate) and bulk samples.Provide a good visual representation of ground conditions.In some cases trial pits are a pre-cursor to other mechanical techniques, the benefits of which are as follows:. Where a cross section is required trial pits are extended laterally to create trenches.
These can be progressed by hand digging (to 1.2 mbgl) or using wheeled/tracked excavators. TGEN have experience of a wide range of investigation techniques, including the following:. TGEN will select the intrusive investigation technique(s) most appropriate to the site, anticipated conditions (geology etc.) and the requirements for sampling (depth, volume, installations etc.). In-situ gas and groundwater monitoring if required.Recovery and analysis of soil, surface water, groundwater and/or ground gas samples for testing against a site specific range of potential contaminants identified within the CSM.Logging of profiles in accordance with BS5930:1999+A2:2010.Excavation of exploratory holes using a range of techniques.An Intrusive Investigation may comprise the following aspects:.
