Freeze thaw Damage
Recommended Solution: Silblock
Freeze-thaw damage can occur when concrete is saturated and exposed to temperature cycles that fluctuate around the freezing point of the pore solution.
Hardened concrete may be damaged by freeze/thaw cycles typical of northern climates. Damage is often observed ... minimizing the effects of freeze/thaw damage includes the use of Sil-block. Concrete is susceptible to damage by many cycles of freezing and thawing. The water inside the pores of the concrete expands upon freezing, and internal stress is developed that can lead to cracking.
