The Pile Driving Monitor is a new device which has been developed to bring modern QA to EVERY pile on site.The PDM is a MULTI-FUNCTION device for foundation projects.

Dr. Julian Seidel is an international expert in foundation design and dynamic pile testing. With his expertise in dynamic pile testing, why did he develop the Pile Driving Monitor? “For many years I have realized that there is a significant and unrecognized risk in driven pile projects. Dynamic pile testing will only confirm capacity for 2 to 10% of project piles. The other 90 to 98% are driven to “set” or “blow count” on the assumption that the piling hammer operates consistently. Many years of PDA testing has shown that on most projects delivered energy varies by 30% or more. The consequence is that piles will routinely be 30% or more under-capacity. The PDM remotely measures pile set and rebound (temporary compression) and pile velocity to allow full and simple quality control of EVERY PILE”.

The PDM uses state-of-the-art opto-electronics to make non-contact measurements of pile movement from 10 to 30m distance from the pile, which removes the PDM from the effects of ground vibrations. Even from this distance, set is measured to 0.1 mm accuracy, and the high digitization rate means that rebound and peak pile velocity can also be measured accurately. No gauges or cables are required. A disposable reflective sticker is all that is required on the pile - then just point and shoot! Finally – pile measurements for EVERY PILE that are fast, simple, accurate, reliable and safe.
