How to Use a Puddle Flange in RCC Slab Construction – Step-by-Step Guide

-
  A puddle flange is a simple yet essential fitting used in civil construction to prevent water leakage where pipes pass through concrete structures. In RCC (Reinforced Cement Concrete) slabs, these flanges act as a seal that stops water from migrating along the outer surface of a pipe. Whether you are working on water tanks, basements, lift pits, or underground pipelines, installing a puddle flange correctly ensures waterproofing and structural durability. This step-by-step guide from Udhhyog , a leading supplier of GI, MS, and SS puddle flanges in India, explains how to use a puddle flange during RCC slab construction. ๐Ÿงฐ Step-by-Step Guide ✅ Step 1: Choose the Right Puddle Flange Select a puddle flange based on the pipe size and material (MS, GI, or SS). GI puddle flanges are ideal for general drainage and water pipes. Use stainless steel for corrosive environments or coastal zones. At Udhhyog , we provide puddle flanges in custom sizes with...
