GI Puddle Flange

GI Puddle Flange

In modern construction, one component plays a crucial role in protecting concrete structures from water ingress — the GI Puddle Flange. Galvanized Iron (GI) puddle flanges ensure a watertight seal where pipes pass through concrete walls, slabs, or foundations. By integrating this simple yet powerful device, long-term damage from seepage can be avoided effectively.

Mesta Inc. is a reputed manufacturer and global supplier of high-quality products. Our innovative engineering and region-specific solutions have made us a preferred choice across Kazakhstan, India, UAE, Saudi Arabia, and Uzbekistan.

What is it?

A GI Puddle Flange is a galvanized iron ring or collar that is fixed around a pipe to create a barrier against water. It is usually embedded into the concrete structure during casting. The main purpose is to block water from seeping along the outer surface of the pipe.

Moreover, the galvanized finish prevents corrosion, especially in moisture-heavy environments such as basements, tunnels, and water treatment plants. Because of its anti-rust properties, this product is widely accepted in high-humidity regions like the UAE and India, as well as in colder climates like Kazakhstan.
