Geotechnical Engineering

Starting with Solid Foundations


Building on solid ground supports financially successful and secure projects. Our clients require a deep understanding of complex subsurface conditions to determine the optimal materials and means of construction for the structures they envision.

Geotechnical engineering is an intricate fusion of art and science. From property oversight to foundational and geologic assessments, GRANT’s geotechnical team understands how the Earth’s composition will affect proposed design or construction systems. Our geotechnical experts use hands-on processes and close collaboration with our other engineers and local authorities to uncover the deep scientific soil, groundwater and bedrock conditions, allowing us to optimally manage the design and construction of every project.


With over 75 years of combined experience, our solutions ensure that our clients’ projects endure, alleviating risk from the onset and saving our clients valuable time, and money on both construction and maintenance.
