A Puddle Flange provides a watertight seal around pipes passing through concrete walls, floors, and foundations.
It prevents water leakage and seepage through the annular space between the pipe and surrounding concrete.
Across Riyadh, Dammam, Jeddah, Jubail, and Al-Khobar, engineers and contractors trust the Puddle Flange in Saudi for reliable waterproofing in sewage, drainage, water supply, and infrastructure projects.
A Puddle Flange is a ring-like barrier fixed around a pipe before embedding it in concrete structures.
When concrete sets, the flange forms a tight bond that blocks water pressure from traveling along the pipe’s outer surface.
It’s commonly used in underground basements, water tanks, retaining walls, lift pits, and manholes.
Available in various diameters—50mm, 80mm, 100mm, 150mm, and larger sizes—these flanges suit both PVC and steel pipes.
Waterproof Seal: Prevents water ingress through wall penetrations.
Easy Installation: Fits directly on the pipe before pouring concrete.
Versatile Design: Compatible with PVC, HDPE, cast iron, GRP, and steel pipes.
Durable Construction: Made from stainless steel, ductile iron, or rubber-coated materials for long-term sealing.
Corrosion Resistant: Ideal for underground or submerged environments.
Maintenance Free: Once installed, it provides permanent leak protection.
Water & Sewage Treatment Plants: Ensures pipe penetration sealing in wet structures.
Basements & Underground Parking: Prevents groundwater from entering concrete walls.
Pump Rooms & Water Tanks: Seals high-pressure pipe penetrations.
Dams & Reservoirs: Strengthens waterproofing barriers.
Industrial Facilities: Used for pipelines carrying chemical or industrial fluids.
Marine Construction: Suitable for retaining walls and underwater tunnels.

1) What is the main function of a Puddle Flange?
It creates a watertight barrier around a pipe passing through concrete, preventing leakage.
2) Can it handle high water pressure?
Yes. Properly cast-in-place Puddle Flanges withstand pressures up to 10 bar or more.
3) What materials are available?
Options include rubber, stainless steel, ductile iron, and GRP, depending on the environment.
4) Are double Puddle Flanges better?
Yes. Double flanges provide extra protection in high-pressure or deep installations.
5) Can I use it for both PVC and steel pipes?
Absolutely. It’s suitable for PVC, HDPE, GRP, DI, and metal pipe systems.
6) Is it reusable?
No. It’s permanently embedded in the concrete during installation.
7) Where can I buy Puddle Flanges in Saudi?
