The testing and quality control of piles at construction and post construction stages has become a common practice in most of the projects. GPL delivers quality services with a focus on safety, value, innovation and excellence.
Our comprehensive pile testing services includes:
Caliper Logging
Caliper log determines the shape and size variations of the drilled pile borehole to assess zones of likely collapse, necking or bulging prior to concreting of the shaft.
Ultrasonic Cross hole Logging
An important very common test to investigate the quality of the shaft concrete and locate defective zones within the pile shaft.
Static Pile Load Test (Vertical, Uplift & Lateral)
Pile Load Test (PLT) is most reliable tests to ascertain pile load capacity and behavior. GPL pro- vides full monitoring of PLT with displacement transducers, dial gauges and load cells including pile shaft instrumentation, in addition to inclinometers for laterally loaded piles tests.
Low Strain Integrity Test
This is a fundamental test conducted on almost all constructed piles to investigate pile shaft integrity and detect defects such as necking and cracking of the pile shaft, in addition to checking the pile length.
High Strain Dynamic Test
This important test determines the pile carrying capacity and settlement properties. The facility enables real-time analysis of the pile data, which can highlight any pile problems while the piling rig is still on site.
Pile Instrumentation by Using Vibration Wire Strain Gauges & Extensometer
The purpose of the static load in compression on instrumented piles are to evaluated the following:
- Load transfer & distribution along the pile shaft.
- Skin friction along the pile shaft.
- Load – Settlement relationship of the pile.
Shrinkage Monitoring
This instrumentation using Vibrating Wire Strain Gauges (Embedment type) is carried out to monitor strain in the concrete structure due to shrinkage. Shrinkage after hardening of concrete is the decrease with time of concrete volume.
Temperature Monitoring of Mass Concrete (Thermocouple Sensors)
Temperature monitoring is carried out during the execution of mass concrete structures of which the character of concrete is technically specified as a structure with large dimensions and has the tendency to rise its temperature due to many factors such as mix design and progress of heat of hydration.
Estimated Concrete Strength by the Maturity Method
The maturity method is a technique that can be used to estimate the strength of in-placed concrete in terms of the temperature and time factor.
