Understanding Surface Cracking Caused by Rapid Moisture Loss
KB Engineering LLC
Acknowledging the causes and implementing preventive measures can help contractors minimize plastic shrinkage cracking.
June 21, 2019
Occurring in both random and parallel patterns, plastic shrinkage cracks are discontinuous, relatively short and typically fairly shallow. Occasionally they can become full-depth cracks. Parallel cracks are typically spaced between a few inches to several feet apart and many times are oriented perpendicular to the prevailing wind direction. Cracks widths at the surface can be fairly wide (as much as 1/8 in.) but rapidly diminish with depth.
