Shaft Area Profile Evaluator (SHAPE®)

A cost effective QA testing device providing a visual representation of foundation excavation prior to concrete pour in wet conditions.

  • Wireless acquisition calculations of shaft profile to determine shaft radius, volume and verticality, 360 degree, 2D and 3D profile views
  • Data acquisition at a rate of approximately one scan per second with eight channels scanned simultaneously
  • Quick connection to Kelly bar or can be used with a top mount winch system

SHAPE® is a cost-effective quality assurance testing device used for deep foundations such as drilled shafts, slurry walls, barrettes and more to determine the excavation dimensions and verticality. 

Drilled shafts are rarely ideal cylinders and irregularities can affect capacity and design. SHAPE® better characterizes the three-dimensional
shape of drilled shafts and other excavated deep foundation elements. SHAPE® provides a fast, economical visual representation of the foundation excavation and verticality prior to placing concrete in wet conditions.

SHAPE® offers:
• Quick connection to Kelly bar or can be used with an optional winch system
• Multi-channel ultrasonic device to scan the sidewall condition of wet pour drilled shafts
• Wireless acquisition calculations of shaft profile to determine shaft radius, volume and verticality
• Data acquisition at a rate of approximately one (1) scan per second 
• Eight (8) channels scanned simultaneously SHAPE’s drilling stem advancement rate is approximately one (1) foot per second,
offering 360˚, 2D and 3D profile views.




Patent No. 10330823

The SHAPE® conforms to ASTM Standard D8232 – Standard Test Procedures for Measuring the Inclination of Deep Foundations.
