In-Situ Video

video-probe-2Another tool to visually confirm the presence of contaminants prior to sampling saving laboratory time and money! A great tool for the dynamic site investigation and Non-Aqueous Phase Liquid (NAPL) plume confirmation.

The video cone is a similar module to the FFD where it can be attached to a CPT cone or pushed alone. When utilized to verify or view subsurface media the real time video is easy way to validate your previous investigative activities. All video is recorded and can be edited to highlight the areas of interest.video-probe

The Video module can be used in series with the FFD module creating a dual purpose combination tool that can identify the presence of hydrocarbons and visually verify them at the same time. This and other environmental products manufactured by Vertek have been used in many elements of the Environmental Protection Agency (EPA) hazardous site investigations utilizing the Triad approach.

 

Modular Soil Sampling

Vertek’s patented Soil Sampler is built for reliable, cost-effective retrieval of soil samples in difficult geologies and is designed to be deployed by most common CPT equipment.

Soil_Sampler_BWCycleable and Reliable

The patented tip release system is strong enough to withstand heavy push loads in stiff soils, yet reliably retracts at the desired depth.

Our field replaceable wear surfaces are made from hardened alloy steel.

Simple Operation

The sample barrel with retractable tip is pushed to the desired depth, a lanyard lowered through the push rods then retracts the tip back into the catch housing. After tip release the lanyard is removed back to the surface and soil sampler is ready for sampling. The sampler and the rod string are then retracted, bringing the sample to the surface. Removing the tip releases the soil sample for ease of Examination and logging. Longer samples can be obtained by threading multiple sample barrels together. The sample sleeve can be clear plastic, stainless steel or split stainless steel depending on sampling requirements. The sampler can be rapidly disassembled for field decontamination.

 

Grouting Tools and Cone

To meet the growing needs of various contractors and state and federal agencies Vertek offers our self grouting tools which allow grouting of CPT holes while removing the rods. Vertek offers two types of grouting tools to fit your needs.grout_cone_cut_out

Non-Cycleable

The Self-Grouting Module is installed in the rod string above the cone and grout is pumped through during withdrawl. The sacrificial ring fits around the module and comes off when the rods are retracted. The design of the module does not allow for cycling and is not recommended for areas with very fine materials.

Cycleable

This Self-Grouting Module is comprised of a standard cone with blow-out plugs that allow grout to be dispensed during extraction. When the grout is pumped through the tube, the plugs are forced out and grout is released through two outlets.

Cost and Time Efficient

Vertek’s Self-Grouting Modules save time and labor by allowing the operator to grout the hole without extracting the rods and then filling the hole by hand. Instead, the operator can seal the hole as the rods are being retracted and all this can be done from the operator control station.

3367_3377Post-push Non-Cycleable Grouting Adapter (tremie method) An additional method of grouting utilizes Vertek’s Post-push grouting system, which requires a second push but is a simpler method than when combined with the CPT push. Our tremie adapter is applied to the end of the rod string with a disposable oversize tip. Tremie method requires a second set of push rods and associated grout mixing tools.

Vertek’s Self-Grouting Modules run the grout tube through the center of the rods alongside the standard CPT cable through the innovative Grout Module Housing which allows the operator to run a probe, extract, and grout without work stoppage.
