In a vessel utilized for providing powdered materials, such as binder, for the construction of an in-situ piling, the vessel has a binder feeding system having a fluidization chamber, where the fluidization chamber receives air at a higher pressure than the substantial portion of the remainder of the vessel. This higher pressure enhances the fluidization of the powered materials as the materials are dispersed through an actuated valve at the bottom of the vessel. This system results in a decreased volume of air required for transporting the powdered materials through the feeder hose to the tool in the piling borehole, thereby reducing the creation of air pockets in the in-situ piling. This feeder system replaces the cell wheel currently used in binder feeder systems.
