    SONIC DRILLING is an innovative way to drill holes faster and easier than conventional methods. The advanced drilling technology fluidizes and displaces soil particles away from the drill bit and the sides of the drill pipe. This allows for clean, rapid penetration rates in a variety of geological formations to depths in excess of 300 feet, offering superior drilling and sampling footage production. Sonic drilling is well suited for unconsolidated overburden, even with cobbles and boulders. Sonic drilling provides outstanding ability to provide truly representative continuous cores in a variety of geological formations, and is suited for both geotechnical and environmental applications.
