Pneumatic-powered track-mounted, percussion drills can be used to perform or augment geotechnical investigations in some karst settings. The air track drill is best suited to exploring bedrock in areas where soil cover is less than ten feet in thickness. Although they do not provide the quality of information available from core drilling, air track drilling does offer some advantage by being able to produce general information about the gross features of the subsurface quickly and relatively economically.
