[NDE]

Foundations Depth & Integrity Methods:

Crosshole Sonic Logging Series

System designed for testing of newly placed critical drilled shaft foundations and slurry walls using ultrasonic logging between water filled access tubes

Impulse Response

For low strain integrity and foundation length determination. Tests both new and existing foundations.

Parallel Seismic Series

For length determination of unknown foundation depths for bridges and buildings even if foundation tops are not accessible

Sonic Echo

For low strain integrity and foundation length determination. Tests both new and existing foundations

Crosshole Tomography Software

For situations where simple CSL in not enough, TOMO-1 allows users to create an image of the size, shape, and severity of any defects present in a drilled shaft. Tomography results presented in either 2-D or 3-D displays, with animation possible

Ultraseismic

Variation of the SE method (above), developed by Olson Engineering. Foundation testing on abutments, walls, and other non-shaft type foundations.

(NDE) Structural, Pavement, & Tunnel Methods:

Slab Impulse Response

Test for subgrade support/void evaluations and structural integrity evaluations of void, honeycomb, delamination, cracking on concrete pavements, slabs, spillways, tunnels, etc.

Impact Echo Series

Flaw detection, concrete thickness testing, masonry thickness testing, with one-sided access for testing on a point-to-point basis.

Spectral Analysis of Surface Waves S Series

For determination of stiffness profiles, i.e., velocity and thicknesses of thin layered systems such as pavements, tunnel liners, structural concrete, etc. without coring and with one-sided access.

Structural Tomography Software

For concrete and masonry structural elements of buildings, bridges and other structures, tomography allows the user to create an actual image of the size, shape, and severity of hidden, internal defects. Tomography test and analysis software includes 2D and 3D displays with animation.

Ultrasonic Pulse Velocity

For measuring the speed of sound and signal strength in concrete, wood, masonry, rock and other coarse-grained material with two-sided access.
