REAL-TIME
EXCAVATION INSPECTION
Remove the uncertainty of drilled shaft excavation inspection with
SONICaliper™. Using sonar technology, it provides a full 360-degree,
three dimensional measurement of shaft excavations for a profile of
shape, alignment and verticality. With immediate detailed results,
engineers, designers and contractors know that shafts have been
constructed according to specification and meet quality standards.

The SONICaliper is a cost-effective quality shape, volume and verticality of the


control and quality assurance tool for deep excavation. SONICaliper provides this
