Because what is under the ground on which a project is to be built is often more important than the condition of the surface itself, Froehling & Robertson, Inc. offers our clients a comprehensive suite of geotechnical drilling services that utilize the latest technological tools and procedures. Whether a client needs F&R to evaluate the strength and composition of the subsurface or test to determine whether there may be soil or groundwater contamination, we have the field and laboratory testing capabilities to support our clients’ specific needs.

F&R maintains its own fleet of drilling equipment as well as accredited geotechnical engineers that offer a comprehensive scope of geotechnical drilling services utilizing diversified drilling equipment with standard testing techniques that include penetration tests and rock coring.  F&R’s drilling staff is trained in applicable ASTM testing procedures and participates in our in-house quality control programs.  As part of our geotechnical services, we perform a wide range of geotechnical laboratory testing services in support of our subsurface exploration.  These tests include, but are not limited to: classification indices, consolidation studies, triaxial and direct shear, unconfined compression, and permeability.  Once the analysis is completed, our professional staff of geotechnical engineers compiles the field and laboratory data into a detailed report of our findings and recommendations which can then be utilized by the project design team and/or owner.
