Why does concrete crack in Lubbock
In Lubbock, the main causes are fast drying in hot, dry, windy weather (plastic shrinkage cracks), soil that shrinks and swells with moisture (especially Randall clay near playas), poor base compaction, and freeze-thaw cycles between about October 31 and April 10. Control joints and curing reduce random cracking.
Common causes
- Shrinkage as it cures
- Missing or late joints
- Soil movement and drainage
