Can pervious concrete be used in climates exposed to freezing and thawing?
In most cases, the strength and durability of pervious concrete make it resistant to potential cracking from freezing and thawing. According to the National Ready Mixed Concrete Association, pervious concrete that is partially saturated should have sufficient voids to accommodate the expansion caused by freezing of water. Structural damage could occur, however, if the pavement becomes fully saturated or the ability of the concrete to drain water is compromised due to clogging of the void structure. NRMCA offers recommendations for preventing these problems in its publication Freeze-Thaw Resistance of Pervious Concrete.
