Subsurface sampling includes NQ and HQ wire line rock coring, split spoon sampling, Shelby tubes, NW casing advancement, vain sheer testing and core hole packer testing. Core samples can be boxed and labeled for transportation to the testing laboratory.
All Terrain Low Clearance Drilling
Eichelbergers Inc. maintains a versatile fleet of track mounted/low clearance rigs for sites with challenging access conditions. The all terrain/low clearance fleet includes the capability for air rotary, hollow stem auger and Geoprobe. The rubber track mounted units may also be used on paved surfaces to minimize the risk of damage.
Split Spoon Sampling
Split spoons are advanced through the subsurface to collect overburden samples. Rigs are equipped with automatic hammers for maximum efficiency. The driller will maintain a log to record the sample and corresponding blow counts necessary to complete the process.
Borings can be advanced to refusal in order to identify the depth to bedrock. This practice is frequently used prior to the installation of water and sewer lines to identify the requirements for trench excavations. If desired, rock coring can be used to identify the specific rock formation where refusal is encountered.
Coring services can be provided through concrete and asphalt surfaces to collect representative samples for compliance testing. Core samples will be boxed and labeled. Traffic control can be included where necessary for sampling on active highways
