The first stage of drilling is static sounding.

A car with a drilling installation arrives for the allotted area for construction. Design designers determine how many wells will be and where they will be located. Usually, they are placed in a place under the foundation, where there will be the main load. For the correct choice of the type of foundation, you need knowledge about the characteristics of the soil of the site on which the building will subsequently be built. The first stage of drilling is static sounding. They start it when they turn the horizontal position of the drilling rig. The metal rod is pressed into the ground and the lateral and frontal resistance of the soil is measured. As soon as the metal rod slows down the immersion rate in the soil, on which there is a regulation of building codes, sounding is stopped.
