baserock
Underlying geological layer
Baserock is the solid, unweathered rock that lies beneath layers of soil, sediment, or looser surface materials.
In geology and construction, it represents the stable foundation on which everything else rests.
Engineers drilling or excavating must eventually hit baserock to anchor structures securely.
The term functions similarly to bedrock, though baserock may emphasize the rock as a base or platform rather than its position at depth.
