Puddle Flanges Explained – The Secret to Waterproof Pipe Installations

Overview of Puddle Flange Systems

Wellfit Engineering is one of the leading puddle flange suppliers and waterproofing component manufacturers in the UAE, delivering high-performance sealing solutions for MEP contractors, builders, and civil infrastructure projects.

A puddle flange is a circular collar installed around a pipe to prevent water seepage where the pipe penetrates a concrete structure. It acts as a permanent barrier that blocks the movement of water along the pipe’s exterior, ensuring a completely watertight seal even under hydrostatic pressure.

Commonly used in basements, water tanks, retaining walls, and underground utilities, puddle flanges are an essential part of any UAE waterproofing and drainage design.

• Prevents water leakage through concrete penetrations
• Resistant to hydrostatic pressure and aggressive soil conditions
