Pile Testing

Accuracy From Start To Finish

DFI pile testing is conducted in accordance with ASTM International (formerly known as the American Society For Testing & Materials) standards. In particular, we most commonly use the following depending on the type(s) of testing used:

  • ASTM D4945-17 – Standard Test Method For High-Strain Dynamic Testing Of Deep Foundations
  • ASTM D1143/D1143M-20 – Standard Test Methods For Deep Foundation Elements Under Static Axial Compressive Load
  • ASTM D3689/D3689M-07(2013)e1 – Standard Test Methods For Deep Foundations Under Static Axial Tensile Load
  • ASTM D3966/D3966M-07(2013)e1 – Standard Test Methods For Deep Foundations Under Lateral Load

Our engineers use your geotechnical data and structural needs to develop a personalized load testing program that meets or exceeds industry standards. Following this we execute static or dynamic tests using our proprietary installation equipment.
Pile capacity testing provides site-specific results of pile performance, which is used to either economize foundation designs (pre-design/pre-construction) or to verify design (post-design/during construction).

Testing Methods

The two main types of testing we perform are dynamic Pile Driving Analyzer (PDA) tests and static capacity tests. Best results generally occur when they are done together. However, there are instances when only one of these methods may be required.

Additionally, for smaller loads, DFI offers quick load testing, which saves time. This type of testing is used mainly for solar projects.

Dynamic PDA Capacity Testing

Dynamic Pile Driving Analyzer (PDA) tests are high strain load tests that assess the capacity of driven piles. They also evaluate shaft integrity, driving stresses, and hammer energy during installation. Our technicians process the data and prepare the final reports.

Static Capacity Testing

Static capacity tests measure the response of driven or helical piles under an applied load. The purpose of such tests is to verify that the load capacity in the constructed pile is greater than the nominal resistance (compression, tension, lateral, etc.) used in the design. Test results are reviewed and processed by our design engineers, and a final report is prepared and delivered.
