DDI team typically deploys Hollow Stem Auger Drilling rigs when drilling to shallow depths (less than 50ft). However, we use them to install monitoring wells up to 8” in diameter either.
Our hollow stem auger technicians are efficient and often work on geotechnical projects to collect soil samples and perform SPT. In addition, they work on environmental drilling projects to sample and construct monitoring or recovery wells. They usually use Track Mounted 7720DT Geoprobes for these purposes. Although, we can use any other drill rigs to perform the jobs depend on the clients’ requirements.
We use Auger drilling systems commonly to set ground water monitoring wells, obtaining soil samples and performing Standard Penetration Testing (SPT) by auto hammer system for environmental and geotechnical applications. Also, we use AMS soil augers for obtaining disturbed soil samples at or near the surface and for boring to depths where samples may be obtained with a soil sampler or soil core sampler.
We use our 7720DT Geoprobe for Hollow Stem Auger Drilling services to the clients. DDI has a full complement of equipment and trained staffs for the below services to take the most appropriate sample possible from a borehole or well:
