  2. Window Sampling Boreholes

Window Sampling Boreholes

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 a technique whereby small diameter cylindrical steel tubes (with cut out windows) are driven into the soil with a mechanical (petrol, electric or hydraulic) hammer and extracted manually or hydraulically. The samplers will show a virtually undisturbed horizon for logging and (sub) sampling.

Window sampling can be used for a range of investigations, including for contaminated land, geotechnical investigations and for the installation of ground gas and ground water monitoring wells

Such rigs are good for investigating areas where access is limited. In addition to the standard window sampling machines, modular and hand-held equipment is available for difficult access such as embankments or basements. Electric rigs are also available for use in areas that may be sensitive to fuel exhaust and/or do not have suitable access for ventilating exhaust fumes.

The equipment is track mounted and is capable of carrying out in situ testing, including SPT/CPTs and dynamic probe testing. Dynamic Probe testing is a continuous soil test procedure which enables the relative density or strength of the ground to be inferred.

  • Cable Percussive Boreholes

    Cable Percussive Boreholes can achieve deeper borehole depths than Window Sampling techniques - over 20m (possibly up to 50m depending on conditions) using a clay cutter through cohesive soils, a casing and shell through granular soils and a chisel to break up rock and other hard layers.

  • Rotary Boreholes

    Rotary Open Hole techniques are employed to investigate the presence of shallow (<30m) coal using a water flush system to prevent the ignition of potentially explosive mine gases for deep observations of coal bearing strata.

  • Trial Pitting

    A trial pit (a.k.a. test pit) is a ground investigation technique that is used as a means of investigating, in large scale, the condition of the ground and the type of strata present at shallow depth, typically before beginning construction works. They are useful for obtaining large volume bulk samples of the ground.
