Our new video "Static Load Tester" is on YouTube

Static Pile Loading Tester is used to evaluate the load resistance behavior of deep foundations.

Static load testing is used to evaluate the load resistance behavior of deep foundations prior to structure construction. It differs from rapid and dynamic load testing in that the load is applied to the deep foundation slower. Static Load Tests can be performed to validate foundation design assumptions regarding the axial compression or axial tension resistance provided by a deep foundation element, or its deflected shape under a lateral load. Conventional readings of the applied load determined from the jack pressure gage and load cell, and deep foundation head movement determined by LVDTs, digital dial gages, or mechanical dial gages, can be combined with the SLT to determine the capacity or nominal soil resistance, the load-transfer behavior under axial loads, or deflected shape under lateral loads. The Static Load Tester also reads strain gages and vibrating wire gages.
