Pit test for pile Dynamic Pile Test PDA Pile echo tester

Pit test for pile  Dynamic Pile Test PDA Pile echo tester

Dynamic load testing (or dynamic loading) is a method to assess a pile's bearing capacity by applying a dynamic load to the pile head (a falling mass) while recording acceleration and strain on the pile head. 

The procedure is standardized by ASTM D4945-00 Standard Test Method for High Strain Dynamic Testing of Piles.

Field of use  

By using the reflected wave method, the device is used to assess the integrity of concrete pile and identify the extent and location of the pile defect. It can be used for testing bored concrete pile and hammer pile. It can also be used for testing the constructions with an exposed top surface such as pillars.
