Our drill rigs are equipped with both rotary auger head and direct push hammer capabilities, which enable us to perform a variety of explorations. The type of boring and sampling methods chosen for a project are often determined by the site conditions, scope, and budget.
Test borings are performed to obtain a subsurface profile by allowing for visual classification of soils through sampling. Soil parameters are obtained through various in-situ testing methods which can be used in conjunction with different types of borings.
