Direct Push Probing - Environmental & Non Destructive Digging Perth - Bibra Lake, Australia

DPP use a 6625CPT machine designed to access hard to reach/confined space areas. The Geoprobe 6625CPT is operated entirely by remote control making it one of the safes pieces of machinery around.

With This rig DPP is capable of carrying out geotechnical investigations using CPT as close a 400mm to a pad/wall or other structure to depths of up to 50m. being track mounted it can go places that larger CPT machines are unable to reach.

In addition to CPTu/Friction cone the Geoprobe 6625CPT is also capable direct push sampling, hollow stem & continuous flite auger and can install groundwater monitoring wells/piezometers.

DPP uses direct push technology to install wells for monitoring either groundwater or soil vapour. These offer a highly cost-effective and minimal-intrusion technique for collecting data on the distribution of groundwater or contaminants in the sub-surface and are typically used to provide trend analysis of contaminant concentrations over an extended period of time.

For groundwater sampling DPP uses small diameter wells (up to 50mm ID) with prepacked screens comprising standard slotted PVC well screen pipe surrounded by environment-grade sand contained within a stainless steel mesh cylinder. This ensures the filter media is directly located around the well screen and allows quicker, more efficient installation.

Groundwater flows into the well under ambient hydrostatic pressure and can be sampled using either mini-bailers or pumps to obtain high integrity water quality samples.

Direct push technology uses a number of techniques to obtain soil gas samples. Single-tube methods provide sampling at single depths as the tool string is advanced and is often used during surveys to define or locate a plume. Dual-tube methods provide soil gas profiling at multiple depths and also allow the installation of high integrity soil gas implants or pre-packed vapour monitoring wells using similar techniques to those used for groundwater sampling.

n addition to its core services Direct Push Probing offers Non-destructive digging (NDD) or potholing in Perth and WA.

Non Destructive Digging is the method of exposing underground cables, pipes and other assets to determine their exact location. Non Destructive Digging, used in conjunction with an accredited service locator and dial before you dig plans, is one of the safest and most cost effective methods of service location/clearance to avoid damage and the associated expensive consequences. The amount of underground assets and the lack of accurate and complete plans of where they are installed, along with the increasing use of fibre optic cable, PVC and other non-metallic conduits for gas and water dictates that when in doubt, the digging/drilling location needs to be cleared via all means available.
