Knowledge of subsurface stratigraphy is essential for every civil engineering project. Our geotechnical consultant team uses a variety of tools and techniques to sample, test and evaluate subsurface information and to create a soil mechanical model for analysis.
For our field investigation we employ a wide range of drilling methods such as hollow and solid stem drilling, vertical and inclined diamond drilling and rock coring, sonic drilling, and cone penetration testing (CPT). As project requirements demand we use non-intrusive investigations such as ground penetration radar (GPR) or multichannel analysis surface waves (MASW) to investigate underground geophysical parameters. In most projects a combination of methods is used to enhance the quality of soil modelling.
Our field investigation and in-situ testing is complemented by our materials laboratory services. Our laboratories, located in Ottawa, the GTA and Calgary, are variously certified for CCIL category C and D soils and aggregates and under MTO’s RAQS system for medium complexity soil and rock, including testing for foundation engineering.
