STATIC LOAD TESTING

Bi-Directional Pile
Load Test (BDPLT)


Advanced high-capacity foundation testing solutions for complex infrastructure and deep foundation verification.

ASTM D8169

Overview

  • Bi-Directional Static Load Testing (BDSLT) is an advanced testing method used to internally apply load within a deep foundation element through specialized jack assemblies such as YJACK360 and OJACK360.
  • The system applies upward and downward forces simultaneously to evaluate shaft resistance, toe resistance, and overall foundation performance under axial compressive loading conditions. YJACK Technology delivers highly instrumented BDPLT solutions tailored for critical infrastructure and complex foundation environments.
