PDA Testing

PDA Testing

The Pile Driving Analyzer (PDA) system is the most widely used system for Dynamic Load Testing and Pile Driving Monitoring. High Strain Dynamic Testing (PDA testing) of piles is used to assess the ultimate axial compressive resistance of piles, and to help determine driving criteria that meet project specifications. PDA testing enables the evaluation of hammer assembly performance, assessment of pile stresses during driving and evaluation of pile integrity.


The principles of HGC have completed PDA testing services for various clients on more than 60 projects throughout Canada. Past projects performed by our staff include the testing of H-piles, open- and closed-ended pipe piles, spirally welded pipe piles, socketed concrete piles and timber piles. Furthermore, our staff have experience with different hammer types including open-ended diesel hammers, hydraulic hammers, and drop hammers.



HGC currently owns and operates the PDA-8G, the newest model produced by Pile Dynamics, Inc. and features eight channels of data acquisition for testing all types of piles. Both cabled and wireless sensors enabling extreme testing flexibility, and testing on congested sites.
