Integrity Testing – Crosshole Sonic Logging (CSL)
GRL Engineers perform csl testing to evaluate the integrity and relative concrete quality of drilled shafts. The test is performed after concrete has cured to determine potential anomalies.
Crosshole Sonic Method (CSL)
GRL Engineers assess the concrete integrity of a drilled shaft using crosshole sonic (CSL) method. After the concrete has been poured, the probes are lowered into the shaft, and pulled simultaneously to scan the length of the shaft.
Non-Destructive, Low Strain Integrity Testing for Deep Foundations
Low strain integrity testing is a non-destructive integrity method performed using the Pile Integrity Tester (PIT).
How Engineers Perform Low Strain Integrity Tests with PIT systems
The low strain tests, also known as PIT tests, are performed after foundation installation and curing, and require minimal pile preparation.
Drilled Shaft Verticality Assessment with the SHAPE
GRL Engineers assess drilled shaft verticality and shaft of shaft using a SHAPE device.
Drilled Shaft Radius, Volume and Verticality Services with SHAPE
GRL Engineers, Inc., offer SHaft Area Profile Evaluator (SHAPE) services to measure and report the characteristics of a wet pour, drilled shaft excavation.
GRL Engineers Drilled Shaft Cleanliness Evaluations with SQUID Animation
In this animation, see how GRL Engineers determine shaft base cleanliness in drilled excavations.
Evaluating Base Cleanliness of Drilled Shafts using SQUID Testing Device
SQUID is used to measure force and displacement at the bottom of a drilled hole, to quantitatively assess the drilled shaft cleanliness.
How Engineers Measure Shaft Bottom Cleanliness with the SQUID
Using the Shaft Quantitative Inspection Device (SQUID), GRL Engineers measure debris thickness located at the bottom of a drilled shaft.
Thermal Integrity Profiling with Cloud Capabilities
Thermal Integrity Profiling is a technology that utilizes the heat generated by curing of concrete to assess the integrity and quality of drilled shafts, augered cast in place (ACIP) piles and other concrete foundations.
Assessing Concrete Pile Integrity with Thermal Integrity Profiling Services
Thermal Integrity Profiling is used to assess concrete integrity during the curing process.
Integrity Testing – Thermal (TIP)
GRL Engineers use Thermal Integrity Profiling (TIP) to assess concrete quality of drilled shafts, augered cast in place (ACIP), micropiles and other concrete foundations. TIP Testing can be done remotely via the Cloud with a GRL Engineer assessing thermal data in real-time.
