Expertise and Strategic Approach

Our approach to geotechnical engineering is rooted in collaboration and technical excellence. We work closely with clients, understanding their vision, needs, and challenges to craft solutions that reflect their project requirements and support their goals. Whether evaluating subsurface conditions for a new roadway, designing foundations for critical infrastructure, or analyzing slope stability for development projects, we ensure that every project is a perfect balance of technical rigor and practical application.

Geophysical Testing

YeDoma has methods of geophysical testing at our disposal, including seismic refraction and resistivity testing. We prefer to use the geophysics testing on the project to determine the depth to bedrock, rippability, and evaluating continuity and corrosiveness of materials. We consider the combination of probing and geophysics leads to much less ambiguous results.

GRIZZLY® Dynamic Probing with Super Heavy Weight Hammer (DCP-SH) Mobile Drill Rig

YeDoma has two DCP-SH Drill rigs. These rigs were developed for anomaly detection, compaction control and for geotechnical studies. The rigs use the same energy specified in the Standard Penetration Test (140 # Hammer with a 30" Drop).

Our technical approach includes discrete sampling using auger flights, split spoons and modified ring samplers overseen by geological and geotechnical engineering specialists. The second drill rig arrived in May of 2022 and has a data integrated computer. The drill rig has been correlated with CPT and SPT and is proven to be incredibly valuable for identifying weak strata, subgrade sampling, and permeability testing.
