Olson's Best Selling Nondestructive Testing System to Test Newly
Placed Shaft Foundations!
The Crosshole Sonic Logging system is the most accurate
and reliable technique for assessing the integrity of deep foundation elements
constructed on-site from concrete or grout. The system is designed for
Quality Assurance (QA) testing of newly placed critical drilled
shaft foundations and auger cast piles, but can also be applied
to slurry walls, mat foundations, and mass concrete pours. Using
water-filled access tubes, CSL testing provides assurance that
the foundation concrete is sound with no defects such as soil
intrusions, necking, sand lenses, voids, etc.
Where defects exist, the extent, nature,
depth, and approximate lateral location of the defects can be determined
with the CSL method and further refined with Tomographic
Imaging Software,
which is sold by Olson Instruments. (Note: Optional Tomo software is available
for the CSL, UPV, and CS/DS add-on test methods)
A variation of the CSL method, called Single-Hole Sonic Logging (SSL)
can also be used on smaller diameter drilled mini-piles and auger cast
piles. The Single-Hole Sonic Logging method is used in cases where only
a single access tube can be placed in a deep foundation, and tests the
concrete quality in the region around
the single access tube.
Training
Hands-on training classes are available for all of our NDE test methods at our Wheat Ridge, Colorado (USA) location, which is a suburb located appromately 15 minutes northwest of downtown Denver. Training may be available at your location by one of our agents upon special arrangement.
