Abstract: An in-situ cast floor underlayment is disclosed in this invention, wherein the floor underlayment comprises a cemented rubber layer, which further comprises rubber granules and cementitious binder. The floor underlayment further comprises a highly deformable cemetitious composite layer on top of the cemented rubber layer for the protection thereof. The rubber granules are pre-treated such that a better interaction between the rubber granules and the cementitious binder is achieved. A method of installing the in-situ casted floor underlayment is also disclosed.

Abstract: A garbage disposer replacement unit for straining food waste comprises a drainage means fitted to one or more sink for transporting food wastes to a sewer system and a main interceptor connected in series with the drainage means. The main interceptor is fluidly connected in series to the sink drain outlet through an adapter funnel and includes a convex reservoir and a number of legs for supporting the main interceptor above a floor. Two opposite side outlets are positioned at the lowermost level of the convex reservoir. A tray is slidingly suspended within the main interceptor above the reservoir, wherein the tray has fine bottom perforations for retaining small particles of food waste. A draining basket is removably positioned under the side outlets for catching escaped wastes bypassing the main interceptor. The interceptor has a top opening over which the adaptor funnel is placed concentrically to redefine the top opening to fit with the existing sink drainage means.

The tray of the main body retains small particles food waste via fine bottom perforations. The tray has a large top opening and a centrally opened adaptor plate to redefine the top opening to fit with the drainage means for the existing sinks in the kitchen.

Abstract: A garbage disposer replacement unit includes a pre-rinse basket with food waste straining holes. A main body houses a tray slidingly suspended that retains small particles food waste via fine bottom perforations. The tray has a top opening larger than a drain diameter of an existing bus bowl in a kitchen. A plastic clip disc pairs with clip top members to clip the main body onto bus bowl flanges. The clip disc drain adapter adjusts and adapts the unit's outlet to different drain diameters of existing bus bowl fixtures. The clip disc and a top clip member constitute a clip assembly for adjustably clipping the unit main body to the given drain flange easily but securely. Optionally, a four-legged riser replaces the clip assembly to attach to the unit main body top for bus bowls with a flangeless standard drain fitting.
