A puddle flange is a vital waterproofing component used where pipes pass through concrete walls, basements, or water tanks. By sealing the joint between the pipe and the structure, it prevents seepage and leakage. Available in GI, CI, SS, ductile iron, and rubber, puddle flanges are trusted in fire water tanks, underground drainage, and building foundations. https://udhhyog.com/puddle-flange-124
