Product Description

Product Description

 GD-WP Low Strain Cunstrution Pile Integrity Tester
 Adopting stress wave reflection method/transient mechanical impedance method, low straind dynamic pile load tester can locate major defects in drilled shafts or concrete piles. The test measures: pile length, or depth to anomalies, pile head stiffness. These parameters are helpful to estimate defects magnitude and location. 
  Compared to other testing methods, low strain pile testing is non-destructive, relatively quick and cost-effective. It will generate a stress wave by the impact of hammer, which will be monitored via accelerometer. The stress wave propagates down the pile shaft and is reflected when it encounters either the toe or a non-uniformity of the shaft.
