Who we are

Pile Dynamics, Inc, a growing company headquartered in Cleveland, Ohio, USA, is the largest manufacturer of foundation dynamic testing equipment in the world. A superb team of civil engineers, electronic engineers, software developers and technicians make the constant development of the PDI line of products possible and highly relevant to the deep foundation industry. PDI excels in product quality and customer support. PDI has a network of sales representatives spread from the Far East to Europe to South America to Australia. PDI products improve the quality assurance of deep foundations on jobsites in over 100 countries throughout the world.


In the mid-1960s, at what is now known as Case Western Reserve University in Cleveland, OH, Professor George G. Goble, became the principal investigator of a research project to develop new technologies of pile testing. The Ohio Department of Transportation and the Federal Highway Administration funded the initial study, entitled “Dynamic Studies on the Bearing Capacity of Piles”, which resulted in an electronic testing device displaying the bearing capacity of a pile based on fundamental stress wave theory.

During that time, as a graduate student, Dr. Frank Rausche, developed the Case Method and CAPWAP® analysis. A short time later, Garland Likins, also a graduate student at Case, joined in both the software and hardware development efforts. In 1972, the trio came together to form Pile Dynamics, Inc. (PDI), a firm dedicated to developing quality assurance instruments for the deep foundation industry, most notably, the Pile Driving Analyzer® (PDA).

PDI continues to innovate the deep foundations industry through the development of quality assurance/quality control testing equipment and technologies. Our technologies are used worldwide on various types of deep foundation structures, both onshore and offshore. We offer customized training in the use of our equipment, as well as certified continuing education through foundation testing workshops, seminars and webinars around the world.

More than ever, Pile Dynamics is committed to quality, research, innovation and superior customer care. And, every PDI instrument includes technical support. Headquartered in Cleveland, Ohio, USA, PDI products excel in quality, reliability, accuracy and durability.

“We not only build pieces of equipment and perform testing, we are actually the developers of the testing methods themselves,”

Dr. Frank Rausche, Founder
