Abstract: A splash block can include a base surface and a raised sidewall surrounding the base surface except for an outlet side of the base surface. The raised sidewall defines an inlet sidewall located opposite the outlet side of the base and a pair of longitudinal sidewalls spanning from the inlet sidewall towards the outlet side of the base. A tab is provided to the inlet sidewall. The tab is attached to the inlet sidewall such that the tab can pivot between a first position extending horizontally outwardly away from the base surface and a second position folded under the splash block such that the tab does not protrude outwardly from the raised sidewall. A first aperture can be defined in the tab to receive an anchor spike. A second aperture can be defined in the base surface adjacent to the outlet side in order to receive an anchor spike.
