VTK Series Grout Cone Penetrometer
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.
Non-cyceable
The Self-Grouting Module is installed in the rod string above the cone and grout is pumped right in 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
Verteks 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.
Our self-Grouting modules run the grout tube through the center of the rods alongside the standard CPT cable through our innovative Grout Module Housing which allows the operator to run a probe, extract, and grout without work stoppage.

Grout Through Cone
A fully capable CPT Piezo Cone is AVAILABLE that enables grouting from the very bottom with a disposable tip.
Datasheet coming soon
Detailed description coming soon. Our grout cone fills in the hole while the cone is being retrieved.
