Wall bases and methods for utilizing the same are provided. A rear surface of the wall base is configured to be secured to an adjacent forward surface of a wall. An extension member extends outward and downward from the base member, and a protrusion extends downward from the extension member. A channel for sealant is defined, at least in part, by the extension member and the protrusion. The protrusion may be separately formed from the extension member and base member.
