Method and apparatus employing modular engageable components for formation of maintenance hole platforms

A method for forming a maintenance hole base having base recesses configured for communicating a fluid flow from one or a plurality of incoming conduits, to each other or to a drain pathway using one or a plurality of formed communication pathways, comprising:

• from a plurality of central core components having one or a plurality of differently sized channels recessed into a top surface surrounded by a descending sidewall, choosing one said central core which is configured with a said channel to yield a said communication pathway in a central area of a formed said base;
• from a plurality of periphery components, configured for abutted engagement with side surfaces of each other, and a with a side surface of said core component, where each of said periphery components has different sized and angled recessed channels formed in a top surface, choosing a plurality of said core components having said recessed channels in said top surface configured to yield properly angled and sized communication pathways to operatively engage with said incoming conduits and said communication pathway in said central area;
• removably engaging said periphery components having top surfaces surrounded by descending side surfaces, to surround said central core component and abut respective top surfaces of said periphery components with respective top surfaces of adjoining periphery components, and with said top surface of said core component, thereby forming a modular mold with a single assembled top surface and surrounding descending sidewall;
• employing polymeric material heated to a moldable temperature, and molding said polymeric material against said assembled top surface and against exposed said descending side wall of said modular mold;
• and
• allowing said polymeric material to cool and removing a formed said maintenance hole base from modular mold.
