A simple adapter screwed on to the drill head allows the existing push and pull hydraulic system to advance and retract the CPT equipment to and from the subsurface. This kit can expand your service capabilities and revenue streams with existing clients. The amount of total push force will depend on the size of your drilling platform and how it is anchored.
Drilling platforms and methods that are most commonly adapted to CPT include:
- Auger Drilling
- Hollow Stem Auger Drilling
- Air and Hydraulic Rotary Drilling
- Directional Drilling
- Direct Push Drilling
CPT data is preferred by most geotechnical engineers as it provides constant data transmitting tip, sleeve, and pore pressure readings 3-4 times a second. Our system allows for frequent advanced geotechnical measurements such as in-situ dissipation tests and the ability to obtain shear wave seismic velocities vs. depth.
Typical Drilling Rig CPT Conversion Kits consist of:
- Peizo-Cone Penetrometer
- Data Acquisition System (DAS) and coaxial communication cable
- Depth market for depth measurement
- Drill head adapter for advancing and removal
- Rods or rod adaptors
- Wear surface consumables and spares (tips, sleeves, pore pressure filters)
- Seismic shear wave equipment (optional)
Common pricing for the above ranges between $35,000 and $50,000 depending on a variety of factors. Contact us today to learn more or get a quote.
By adding CPT to your existing SPT capability, projects that require CPT testing can be completed by your company creating a one stop shop for your clientele. This initial step into the CPT business will allow your existing crews to obtain a higher daily rate which generate more revenue for your company and expand your customer offerings separating you from your competition.
If you’re considering growth of your drilling business and providing additional capabilities to your customers, this is the best and most cost effective option to enter the CPT service marketplace.
