Site Investigation

Hand-held window sampling

Percussive window sampling can also be carried out using a portable jack-hammer system. The sample tubes are driven into the ground using a hydraulic hammer and are then retrieved with the use of a compact mechanical jack.

This system is ideal for use in sites with restricted access where conventional window sample rigs are unable to be used. Extra-long hydraulic hoses can be provided to allow the power pack to be located away from the working area, this could be used to alleviate the problem of exhaust fumes when working in confined spaces.
