A gravel packing apparatus (210) having expandable channels (244) comprises first and second tubulars (212, 214) forming an annulus therebetween. First and second base plates (230, 232) are positioned within the annulus, each base plate (230, 232) having at least one receiving notch (234, 236). An expandable channel (244) having first and second configurations extends between the respective receiving notches (234, 236) of the first and second base plates (230, 232) within the annulus. Each expandable channel (244) initially has a flexible hose (252) disposed therein such that when the flexible hose (252) is pressurizing, the expandable channels (244) are expanded from the first configuration to a second configuration, thereby forming slurry passageways in the gravel packing apparatus (210).
