HIGH STRAIN DYNAMIC PILE TESTING (PDA TESTING)|
(conforms to ASTM D4945-00)
PDA Testing utilizes the Pile Driving Analyzer (PDA) and is based on the theory of Stress Wave Propagation on
Piles (CASE Method). Force and acceleration measurements taken near the top of a pile during impact provide the
necessary information to determine:
* Activated bearing capacity
* Hammer performance
* Maximum driving stresses
* Pile integrity
PDA Testing can be used on all types of piles, such as concrete piles, bored piles, steel piles and so on. For
large diameter bored piles, 4 pairs or strain transducers and accelerometers are used.
Results such as pile integrity can be evaluated on site and would allow the engineer to accept or reject the pile
immediately. Actual driving stresses and hammer performance data obtained during pile driving can reduce pile damage.
Piles no longer need to be overdriven, resulting in lower foundation cost.
* Tests deep foundation integrity quickly and economically
* Used worldwide for more than 30 years
* Conforms to ASTM D4945-00
