Moisture will still seep in, but the amount that passes through depends on two factors: the amount of water running and the quality of the concrete used. Sadly, there's not much you can do to limit the cement board's exposure to water. The better approach here is to use high-grade concrete with better resistance to water and moisture buildup.

Concrete is characterized by the type of aggregate or cement used, by the specific qualities it manifests, or by the methods used to produce it. In ordinary structural concrete, the character of the concrete is largely determined by a water-to-cement ratio. The lower the water content, all else being equal, the stronger the concrete.
