Scope of Civil Testing (Concrete Pile)

Lonestar is equipped with state of art, most advanced Dynamic Pile Load Test equipment

Dynamic Load Test is performed on the driven piles or drilled shafts by attaching accelerometer and strain transducers to the top of foundation. These sensors measure the force and velocity under the dynamic load generated by an impact ram. A pile driving analyzer (PDA) conditions processes that measured signal.

When it comes to assessing foundation integrity, Lonestar is equipped with Low Strain Pile Integrity Test equipment and perform test as per ASTM D5882.

An accelerometer is attached to the top of pile head. An impact is generated by striking a light weight hammer to produce stress waves that travels down. The propagation signal is recorded through accelerometer on the screen of Pile Integrity Tester.
