Bedrock

As a solid rock (also called " the Pending " ) is called in geology rocks, which are still in a substantial association with the rocks of the underground ( " bedrock "). It shows the encountered at precisely this point geological conditions. A broken from a rock wall block would therefore not be present.

The bedrock must not visible at the surface ( open ), but may be covered by recent sediments or soils. So when bedrock is also referred to the solid rock under geologically very young unconsolidated material.

The above definition is, however, not apply in the context of engineering problems, especially in the context of civil engineering projects, since in principle the total cubic volume of excavated soil is referred to as.
