Cone Penetration Testing

Cone Penetration Testing (CPT) uses a cylindrical cone pushed vertically into the ground at a constant penetration rate of 20mm per second. During penetration, measurements are made of the cone…

Thermal Conductivity (Resistivity) Testing – Seabed CPT

Thermal Conductivity Testing is primarily used for route surveying and subsequent design of high-voltage electric power cables and for heated pipelines. The measurement method is based on the Non-Steady-State Probe…

Piston Tube Sampling

Developed by Probedrill, the Piston Tube Sampling technique is based on traditional piston type sampling methods but includes the speed and efficiency of a CPT rig, where suitable soil conditions…

Vibrating Wire Piezometer

Probedrill can install Vibrating Wire Piezometers (VWP) to a requested depth (either sensor down or sensor up) in a timely manner, without the need for costly borehole construction. An initial…

Dilatometer Testing

A Dilatometer Test (DMT) consists of pushing flat blade into the soil, to a desired depth using a CPT rig. Once the test depth is reached, a circular steel membrane…

Seismic Cone Penetrometer Testing (Dual Geophone) SCPT

To measure down-hole shear wave propagation speed during cone soundings, we recommend using a Seismic Cone Penetrometer (SCPT). A seismic test is performed at given depths of probing, testing from…

Standpipe Installation

Probedrill can install 20mm P.V.C, 25mm P.V.C, 32mm P.V.C or 50mm P.V.C (plain or slotted) Standpipes for water monitoring use. Standpipe SizeOuter Diameter (OD)Inner Diameter (ID) 20mm26.9mm23.7mm 25mm28mm34mm 32mm42.4mm37.4mm 50mm…

Piezocone Testing

Piezocone Testing (CPTu) is used to determine the groundwater pressure and measures excess pore pressure generated during a CPT. Dissipation testing can be conducted during a Piezocone Test (CPTu) and…

Electronic Plate Load Testing

Electronic Plate Load Testing is used to determine the strength characteristics of soil in situ, by measuring the amount of deformation and force when a rigid plate is forced to…

Electric Vane Shear Testing

The Electric Vane Sheer Test (VST) is used to estimate the undrained shear strength of fully saturated clays, without disturbance. The VST equipment consists of a four-blade, stainless steel vane…

Soil Sampling

Probedrill provides a range of soil sampling options, depending on the type of soil and the testing requirements. The range of sampling options are: Probedrill Soil Sampler (where half metre…

Seismic DMT

Seismic Dilatometer (SDMT) is the combination of the standard Flat Dilatometer with a seismic module. The probe is fitted with two sensors, spaced 0.5m, for measuring the shear wave velocity…

Ball Penetrometer

Ball Penetrometer, or “full flow penetrometers”, have been designed to give a projected area 8 times that of the cone shaft. Advantage of using Ball Penetrometers to standard CPT cones…

Vacuum Potholing

Probedrill can offer Vacuum Potholing as an additional on-site service. We have a 3000w industrial vacuum for installing a 1m or 1.5m PVC pipe which is then used to probe…

Sediment Sampling

Our Sediment Sampler is ideal for very soft, saturated samples and environmental sampling, such as river beds. Our Sediment Sampler has been used to take samples on a tailings dam…

Resistivity / Conductivity

There are many applications where a conductivity cone can be used. The conductivity cone can evaluate the degree of contamination of a soil containing electrolytes (the compounds dissociating into ions…

Water Sampling

Our CPT rigs are equipped with a manual pump (sipper) which can be used to retrieve water samples from an installed 20mm standpipe. A 12-volt water sampling pump is also…

Dual Tube Sampling

The Dual Tube (DT) 325 Soil Sampling System (from Geoprobe) uses a combination of cutting shoe, sheath, and liner retainer to allow efficient recovery of samples in formations ranging from…

MIP / ROST Environmental Testing

Probedrill has the ability to intergrade a Membrane Interface Probe (MIP) or Rapid Optical Screening Tool (ROST) sub into our current set-up on any rig. This type of in-situ environmental…
