Rehabilitating marine structures or designing new buildings or bridges using existing foundations requires testing to determine the length of existing piles, footings and drill shafts. Our pile testing experience includes timber, pre-cast concrete, auger cast, sheet, and pipe and “H” piles. If pile tops are exposed NDT uses reflected compressional waves to determine their length. The length of steel pipe piles, sheeting and “H” piles can also be determined by using a nearby boring and magnetic measurements.
NDT performs quality assurance testing of drill shafts with cross hole measurements, however there are occasions when cross hole measurements tubes are not available. In these cases we use sonic/ultrasonic reflection testing to determine the length of piles and verify the integrity and construction length of drill shafts.
