Test Applications Method Access

Pavement, Structural & Tunnel Systems

Impact Echo (IE)

ASTM C1383

• Determine the thickness of concrete or masonry elements.

• Detect internal flaws and for QA of repairs.

IE Test Head with built-in displacement transducer and impact hammer taps the concrete creating a sound wave.*

Access to only one side of the concrete (or masonry) element is required.

Impact Echo Scanner (IES)

ASTM C1383

• Determine the thickness of concrete

• Diagnose voided post-tensioned bridge ducts, void/honeycomb, cracking, delaminations, and thickness profiling.

Rolling IE Scanner with built-in displacement transducer and impactor takes a reading every 25 mm (1 in).

Access to only one side of smoother finish or formed concrete up to 1 m (3.3 ft) thick.

Surface Wave Testing (SASW)

ACI 228.2R

• Concrete quality vs. depth for forensic damage assessment.

• Condition assessment of concrete slabs and tunnel liners.

Surface waves are created by a hammer strike and collected by two receivers which are in-line at a set spacing.

Access to only one side of the concrete element is required.

Slab Impulse Response (SIR)

ASTM C1740

• Used for finding and mapping voids below concrete slabs, pavements, dam spillways, and behind tunnel liners.

• Used on concrete structures for defects.

The slab surface is struck with an instrumented impulse hammer and the response collected by an adjacent receiver.

Access to only one side of the concrete element is required.

Foundation Depth & Pile Integrity Systems

Sonic Echo/Impulse Response (SE/IR)

ASTM D5882

• Evaluate pile integrity.• Determine the length of deep

foundations.

The foundation top is struck by a hammer and the response of the foundation is monitored by an accelerometer and/or geophone receiver.

Either the top or access to the upper side are required for foundation testing.

Parallel Seismic (PS)

ACI 228.2R

• Used to determine the lengths of deep foundations that are long and slender.

• Investigate foundations with inaccessible tops or unusual construction.

The foundation is struck by a hammer and the response of the foundation is monitored by a hydrophone or geophone receiver lowered down a cased borehole.

A 50-100 mm (2-4 in) diameter cased borehole is drilled to 3-5 m (9-15 ft) below the foundation.

A versatile and expandable Nondestructive Evaluation (NDE) Data Acquisition (DAQ) platform for QA/QC and infrastructure condition assessment. Olson’s NDE-DAQ is used to investigate:

MULTIPLE NDE TESTS ON ONE DEVICE

The NDE-DAQ is Olson Instruments newest data acquisition platform for nondestructive evaluation. The NDE-DAQ is a robust, 4-channel data collection unit that allows for real-time data collection and interpretation, when used in conjunction with a user-supplied Windows tablet or laptop. The NDE-DAQ’s six in situ testing techniques offer powerful tools with which to locate and diagnose defects, or investigate structural and foundational elements.

* Note: Optional 0.1 kg impulse hammer and accelerometer

The NDE-DAQ is used in conjunction with a user-supplied tablet or laptop

The user-supplied platform must have a screen resolution of 1366 x 768

No Ultrasonic Pulse Velocity Test, Requires NDE 360 or FDPC

Note: Runs on your Windows tablet or laptop computer

Olson Instruments designs and builds NDE systems that are first used

by our sister company, Olson Engineering, Inc. before being sold

as field-proven instruments worldwide. This development approach

provides the quality, ruggedness, and performance demanded by

construction industry standards. Furthermore, since our systems are

assembled in-house, the purchaser can be assured that we have the

bench strength to provide assistance for years to come. If you call in for

tech support, more often than not you will be speaking with an engineer

who has actually designed and used the equipment. With Olson’s broad

knowledge and experience, we provide personalized service for all of

your NDE instrumentation needs.
