Praad Geotechnical has extensive experience in geologic field mapping and subsurface explorations, including conventional soil sampling as well as continuous soil/rock sampling. We have performed and supervised numerous explorations involving small and large diameter drilling, downhole logging, and trenching.

We conduct in-situ tests such as cone penetration testing, standard penetration testing, and field density testing (sand cone).  We also conduct suspension logging and seismic piezocone testing to determine the dynamic properties of soil and rock.

Praad Geotechnical provides a variety of services related to field instrumentation.  Instrumentation services include pre-construction surveys, construction monitoring, post construction monitoring, and forensic monitoring. Our experiences include the installation and monitoring/observations of:

• Wells

• Slope inclinometers

• Piezometers

• Crack gauges

• Tiltmeters

• Monitoring of load strain gauges

• Floor level (manometer) surveys

Our field testing equipment includes:

• A slope inclinometer probe for monitoring lateral land movement

• Ground water monitoring devices

• Thin-walled and California drive samplers to obtain undisturbed samples in test borings

• Sand cone equipment to determine the density of the soil in the field

• Vane shear equipment

• Penetrometers (including a U.S. Army Corps of Engineers field penetrometer)

• Survey equipment

 Downhole logging and slide plane observed in borehole

Praad Geotechnical offers deep foundation testing and engineering services.  These services include cross-hole sonic logging and low strain dynamic testing for evaluating the integrity of caissons and piles, dynamic pile monitoring using a Pile Driving Analyzer (PDA), and dynamic load testing for verification of bearing capacity and shaft resistance of caissons, as well as energy calibration for the standard penetration test (SPT).
