A device for protecting objects such as houses, industrial and commercial buildings, storage vessels, boat moorings, and the like from rising water, as in floods, is described. The device comprises a lifting component, termed a liquilift, which act to raise the objects being protected above the rising water. Two types of liquilifts, sealed and nonsealed, are described. Although a single liquilift may be used effectively to protect objects from rising water, preferred embodiments of the invention employ several liquilifts. For example, one form of the invention provides for a generally rectangular support frame, to which the object being protected is attached, to be supported by four liquilifts, disposed near the corners of the support frame. Controls to sense the level of rising water, and to maintain the support frame in a horizontal position, are described. The device also includes a power supply to activate the components thereof.
