A drainage device for use under a floor in a structure including the floor, a foundation wall, a footing located below the foundation wall and a drain. The drainage device is constructed for placement on the footing adjacent to the foundation wall prior to installation of the floor to permit water to flow along the footing under the floor to the drain. The drainage device includes a wall member and spaced apart feet depending from the wall member. The feet are engageable with the footing at spaced apart locations for vertically spacing the wall member from the footing. The feet define fluid flow channels for water seeping from between the foundation wall and the footing and allow water to flow freely underneath the floor and along the footing toward the drain. The wall member being formed of a material capable of transmitting light in the visual range so that any foreign matter located below the wall member and potentially blocking the channels will be apparent upon visual inspection from above the drainage device prior to installing the floor over the drainage device.
