MC5 & MC7 Soil Sampling
MC5 ( Macro-Core 5)
The Macro-Core5® Soil Sampling system (MC5) is the most frequently used direct push soil sampler Geoprobe has to offer. This 1.5-inch diameter, piston-operated sampler features a positive release system that eliminates the uncertainty of continuous sampling! A major advantage of the Macro-Core5 Sampler is that it is one sampler with two sampling options. When sampling from the ground surface or continuous sampling from cohesive soils, APIC utilizes the Open-Tube Method. If sampling from below the ground surface in a previously cored probe hole, or in unstable soils, APIC utilizes the Closed-Piston Method.
The Macro-Core5 Piston Rod Sampler is not designed for driving through undisturbed soil. A probe hole must be opened above the sampling interval either by removing continuous soil cores with an open-tube sampler, or by advancing a Macro-Core5 Pre-Probe to depth.
Features and Benefits
- Sample retrieved in clear PVC liner
- Causes less disturbance to the natural formation
- Sample Size: 1.5” diameter up to 5’ length liner
- Continuous sampling and Discreet sampling
- Determining hydraulic conductivity using the Pneumatic Slug Test Kit
- Open Tube sampling and Closed-Piston sampling
- Excellent performance in harsh conditions
- Discreet sampling allows faster sampling from different depths
- No soil cuttings to dispose of (save $$$)
- Soil sampling depths have been achieved to 100’ in Canada
- Successful in retrieving sample in flowing sand conditions
MC7 (Macro-Core 7)
Soil Sampling has long been the mainstay of direct push work. Geoprobe® soil probing methods continue to replace other drilling methods for environmental, geotechnical, and mining & exploration purposes largely due to their ability to quickly and efficiently recover soil samples.
The Macro-Core7® Soil Sampling system (MC7) is a solid barrel 3.5” or 3.75”, either open tube or piston sealed, direct push device for collecting discrete or continuous interval samples of unconsolidated materials at depth.
This 3.0-inch diameter PVC liner, piston-operated sampler features a positive release system that eliminates the uncertainty of continuous sampling! A major advantage of the Macro-Core7 Sampler is that it is one sampler with two sampling options. When sampling from the ground surface or continuous sampling from cohesive soils, APIC utilizes the Open-Tube Method. If sampling from below the ground surface in a previously cored probe hole, or in unstable soils, APIC utilizes the Closed-Piston Method.
Features and Benefits:
- Increased sample volume size for
- Increases sampling alternatives - groundwater, soil, or soil gas
- Provides flexible range of sample intervals
- Minimizes waste disposal requirements
- Provides minimal disturbance to samples
- Minimizes need for permanent sampling points
- Features minimal intrusion to site
- Increases speed of site characterization
Advantage Probe & Injection Corps Geoprobe 6600 machine deploys with ease and is ready to begin sampling in just minutes. In less than five minutes you are often able to achieve desired sample depths using the either the MC5 or MC7 soil sampling systems. Soil sampling is generally conducted at 5' intervals. APIC is capable of producing a minimum of 100 to 200 linear feet per day in optimum subsurface conditions. Added benefits of direct push type soil sampling include the ability to recover continuous soil cores through holes barely larger than the core itself, the absence of cuttings, and the ability to recover cores using relatively small and highly mobile machinery. With the benefits like these, it's no wonder that direct push soil sampling continues to grow.
