Window sampling or windowless sampling is a technique used to bore through shallow soft soils to investigate the substrata in order to gain a profile of the ground conditions and to facilitate soil sampling for chemical and geotechnical analysis.
Window sampling is carried out by either Terrier, Competitor or Competitor Dart machines which are capable of boring up to 10.00mbgl and have the facility to take U100’s, U38’s and STP’s (Standard Penetration Tests).
Window sampling can be used for the investigation of contaminated land, for geotechnical investigations and for the installation of ground gas and ground water monitoring wells.
These rigs are particularly good for investigating in areas of limited access, and even have the capability to remove the front mast to sqeeze into tight spaces.
