Subsurface exploration is one of the first and most important steps in designing the foundation for a new building or roadway. When properly performed, the most practical, cost efficient foundation design can be utilized. Unlike most other construction materials, soil is far from homogeneous and differs greatly from site to site, even within a site. Our subsurface exploration services are performed on commercial and industrial sites such as: schools, hospitals, government buildings, mills, etc. Our drilling rigs are setup to sample rock and any soil type from gravel to clay. This procedure allows us to extract samples for testing and ultimately for concise and specific foundation design recommendations.
