Quality Control, Geotechnical Instrumentation and Monitoring

Portancemetre
  • Continuous measurement of bearing capacity for capping layers

"in-situ" Compaction Control
  • Measurement of Compaction degree of soil and aggregate layers, through nuclear surface gauges or through the traditional sand bottle method.

Plate Load Tests
  • "In-Situ" evaluation of vertical elastic modulus (Ev) and modulus of subgrade reaction (Ks) according to NF P 94117 and DIN 18134 standards, respectively.

Vertical Inclinometer Systems
  • Evaluation of horizontal displacements in depth, in two orthogonal directions.

Inclined Extensometers
  • Allows evaluation of horizontal displacements along with vertical movements (settlement) within the instrumented casing.

Pile Testing
  • Sonic Pile Testing (TDR2) - The method of dynamic response (TDR2) measures the applied force to the pile, operating in the field of time and frequency. Allows an assessment of the pile axis, in 3 dimensions, and the pile length.
  • Cross-Hole Sonic Testing - This system allows testing piles of large diameter, the analysis provides a model to two dimensions (2D) and three dimensions (3D) of the axis of the pile. SC-XT2000 is a cross-hole test where an ultrasonic transducer is used to measure the time of sound propagation in concrete.
