Freeze-thaw Cycles and Concrete Grinding. Because concrete is porous, it absorbs water. When the wet concrete freezes, that water expands and causes the pores of the concrete to pop. Over time, this expansion due to freezing and thawing, then refreezing, causes damage to the concrete slab. When the surface of the concrete is ground down, …
