APPLE8 Dynamic Load Test – Slow Motion Drop Weight

APPLE Dynamic Load Testing Systems are an attractive alternative to static testing of any deep foundation and are designed to activate a large range of test loads.

Dynamic Load Testing with APPLE Systems

GRL’s APPLE dynamic load testing systems can be configured for a wide range of weights and delivered to projects anywhere in the continental USA.

How Engineers Perform Dynamic Load Tests with Drop Weight Systems

Using APPLE drop weight systems, GRL Engineers can perform high strain dynamic load tests on drilled shafts and driven piles.

Estimating Top-Load Movement and Base Resistance with Bi-Directional Static Load Testing

GRL Engineers offers bi-directional static load tests using a pressurized GRL-CELL.

How Engineers Use Bi-Directional Static Load Testing with Pressurized Cells on Drilled Shafts

GRL Engineers use the Bi-Directional Static Load Test on deep foundations to determine load capacity.

Safe and Economical Dynamic Pile Monitoring

GRL Engineers perform Dynamic Pile Monitoring to obtain and evaluate driving system performance, driving stresses, pile integrity, as well as the soil resistance magnitude and resistance distribution.

How Engineers Monitor Pile Driving with the PDA

High strain dynamic load tests are performed by installing accelerometers and strain sensors on a pile and using a Pile Driving Analyzer (PDA) to monitor pile driving and hammer impact.

Assessing Drilled Shaft Integrity with Crosshole Sonic Logging

Concrete quality is tested by GRL Engineers using crosshole sonic logging (CSL) methods.

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.

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.

How Engineers Use Static Load Testing to Validate Foundation Designs

Static load tests are performed to assess pile movement responses to applied load which help validate foundation designs for construction projects.
