Fernco Puddle Flanges provide an effective solution against water penetration, reducing the risk of emitted gases in concrete structures which may cause damage to residents and buildings.

During the casting process, the puddle flange material is compressed and when the concrete shrinks during curing, the puddle flange material relaxes to block any ingress paths, providing a pressure-tight seal against water, gases and hydrocarbons such as oil and petrol.

• Cost-effective

• Easy to install and widely used as a radon barrier

• Provide a pressure-tight seal against water, gases and hydrocarbons

• Can be connected to all standard pipe materials such as steel, plastic, and stoneware, and installed on walls, floors and ceilings

• Range of sizes available ‘off-the-shelf’

• Made from high-quality EPDM

• Pressure-tight to 10 bar

• High chemical resistance
