Damages

Heaving bedrock is a distinct geologic hazard in certain areas in Colorado near the base of mountains where the sedimentary bedrock layers are steeply dipping (upturned and tilted). In such areas, the bedrock layers may swell unevenly to form linear heave features along the ground surface. Houses and structures built over such heave features may be subjected to extreme amounts of vertical and lateral stress, and the resulting damage can be severe. Offset foundations, driveway slabs, roads, and sidewalks are common disruptions from heaving bedrock.
