Puddle Flanges: Ensuring Watertight Pipe Penetrations in Concrete Structures
Welcome to CIC, your specialist manufacturer of high-quality puddle flanges (also known as pipe sleeves or wall collars). Our puddle flanges are expertly designed to create a secure, watertight seal for pipes passing through concrete walls, floors, and tanks. We provide robust solutions to prevent leakage and protect the structural integrity of your constructions in demanding environments like water treatment plants, basements, and reservoirs.
Why Choose CIC Puddle Flanges?
- Leak-Proof Design: Our puddle flanges feature a continuous water stop plate (collar) that is integrally welded to the pipe sleeve, providing an effective barrier against water seepage along the pipe’s outer surface.
- Durable Materials: Manufactured from high-grade materials for longevity and corrosion resistance:
- Carbon Steel (e.g., IS 2062, A36, S275JR) – often supplied with protective coatings (e.g., hot-dip galvanized, epoxy painted)
- Stainless Steel (e.g., SS304, SS316) – for superior corrosion resistance in aggressive environments.
- Custom Manufacturing: We can fabricate puddle flanges to your exact specifications, including pipe diameter, sleeve length, collar diameter, and material requirements.
- Robust Construction: Our puddle flanges are built for strength and durability, ensuring they withstand the pressures of concrete pouring and long-term service.
- Versatile Applications: Suitable for a wide range of pipe materials (steel, ductile iron, PVC, HDPE) that pass through concrete structures.
- Easy Installation: Designed for straightforward integration into formwork before concrete pouring.

- Welding: Full penetration welds for collar attachment.
How Puddle Flanges Work
The puddle flange is cast directly into the concrete structure. The pipe sleeve allows the service pipe to pass through the wall. The projecting collar (water stop plate) embedded within the concrete provides a physical barrier, preventing water from tracking along the interface between the concrete and the pipe sleeve. This creates a durable, watertight seal crucial for preventing leaks in foundations, tanks, manholes, and other concrete structures.
Applications
Our puddle flanges are essential components in a variety of construction projects, including:”
- Water Treatment Plants & Wastewater Treatment Plants
- Reservoirs & Water Tanks
- Basements & Foundations
- Tunnels & Culverts
- Pumping Stations
- Manholes & Chambers
- Swimming Pools
Quality and Material Options
- Materials: We primarily use:
- Carbon Steel: IS 2062 Grade A/B, ASTM A36, S275JR, or equivalent. Coatings include Hot-Dip Galvanizing (to IS 4759 / ASTM A123), Epoxy Painting, or other specified coatings.
- Stainless Steel: Grade 304/304L, 316/316L for enhanced corrosion protection.
- Welding Standards: All welding is performed by certified welders in accordance with [mention relevant welding standards like AWS D1.1 or IS 816].
- Inspection: Dimensional checks and visual weld inspection are standard. Additional NDT (like DPI) can be arranged upon request.
