This chapter discusses the various rock and soil sampling techniques and the procedures followed. Sampling techniques must be selected according to the soil to be tested. They use several methods: wells, trenches, excavation and tunnels (mechanically or manually dug); manual drilling (done by hand with an auger); punch drilling, and rotation drilling. Drilling can be classed into three categories as core drilling, semi‐destructive drilling, and destructive drilling. The procedures followed are not arbitrary. They are now defined by a standard. Deep reconnaissance is limited to several meters in fine soils. It collects soil with two jaws enabling the ascent of the disturbed soil to the surface. Sampling techniques must be selected according to the soil to be tested. For rock drillings, the fracturing density is stated and called the rock‐quality designation (RQD). This allows the classification of rocks based on their weathering.
