ZALIG engineers have comprehensive knowledge and significant experience in ground investigations. We own a fleet of various types of drill rigs (CME 750, CME 55, CME 45 etc.), accessories and specialized in-situ testing equipment, such as a Cone Penetrometer with pore pressure and seismic measurements, Dilatometer, etc. and Zalig professionals are trained to interpret specialized in-situ testing. Our engineers apply advanced technology to determine the geotechnical parameters of soils and rocks.

Our In-Situ Geotechnical Testing include : - Standard Penetration Test (SPT) - Cone Penetrometer Test (CPT) - Falling Weight Deflectometer (FWD) - Shelby Tube Sampling - Field Soil Resistivity – Wenner Four Electrode Method - Dynamic Pile Monitoring (Applied during driving) - Dynamic Load Testing (Applied following Pile installation)
