Ultrasonic Pulse Velocity

Ultrasonic Pulse Velocity (UPV)

Ultrasonic Pulse Velocity (UPV) testing is used to determine the integrity and quality of structural concrete or stone (up to 6 feet thick) by measuring the speed and attenuation of an ultrasonic wave passing through the element being tested. Areas with lower velocities typically have lower density and strength relative to high velocity areas. Data collected along multiple test paths can be used to create tomographic images of defects.

Identify voiding, honeycombing, cracking and other defects
Identify areas of low-quality concrete
Define the size and shape of a defect by using multiple test paths
Two-sided access required for direct-path testing
Test around corners when complex geometry precludes direct-path testing, such as at beam intersections
Test across a surface for surface-opening crack depth measurements

Sonic Pulse Velocity (SPV)

Sonic Pulse Velocity (SPV) testing is used at lower frequencies for distances greater than 6 feet, such as large columns, beams, and dams.

Test concrete, stone, or wood members up to 25 feet thick

Applicable on:

Elevated Slabs
Columns
Beams
Dams
Members with Two-Sided Access

Test for:

Voids
Honeycomb
Cracks
Delaminations
Strength of Early Age Concrete

The UPV System

Ultrasonic Pulse Velocity (UPV) investigations are performed to assess the condition of structural members if access to both sides is available.

Quality Assurance
- Determine the integrity of structural concrete
Diagnose Defects
- Identify and map voids, honeycomb, cracks, delaminations, and other damage
Test New Pours
- The UPV system can predict the strength of early age concrete

Variety of Materials
- Test on concrete, wood, masonry, stone, ceramics, and metal materials
Testing Options
- The two surfaces used for testing can either be a direct transmission, semi-direct transmission, or an indirect transmission
