Freeze-Thaw Cycles
Sioux Falls experiences approximately 75 freeze-thaw cycles annually, with frost penetrating nearly 4 feet into the ground. Water trapped in masonry and concrete expands roughly 9% when freezing — generating forces that far exceed the tensile strength of these materials. The result: progressive microcracking, scaling, spalling, and mortar deterioration that compounds every season.
“Midwest winters cycle above and below freezing often. When concrete and masonry is saturated, water expands approximately 9% when freezing — causing microcracking, scaling, and spalling that accelerates every season.”
