Puddle Flanges - Wall Collars

Pipe through wall sealing

Puddle Flanges WA-PF waterstop style, prevent water from migrating along the outside of a pipe into the building. Stainless steel bands clamp the waterstops firmly to a pipe and are cast in the wall attached to the pipe.

Foundation Walls, Pool Walls, Floor Slabs are made watertight when a puddle flange is attached. WA-PF Puddle Flanges fit all American and International pipe sizes.

Puddle flanges waterproof sealing systems, are easy to install and may be used on all pipe types. They alow pipes to continue through a concrete without wall sleeves and create a water tight passage for the pipe.

EDPM puddle flanges:


Puddle flanges WA-PF models have raised profile ridges on the collar that creates a bonding surface with the concrete.

EDPM elastomer collars have a thick disk that compressed during the pouring process and relaxes into shrink cavities during the concrete drying process. EDPM rubber disks units are pressure-tight up to 145 psi (10 bar).

The rubber density is 1030 Kg/m cube with a tensile strength of 8/N/mm square. They prevent water creep along the pipe exterior into a building structure.

316L stainless steel tightening bands firmly attach the puddle flange to the pipe.


Puddle flanges may be used with a PVC wall sleeve. The puddle flange will prevent leakage along the outside of the wall sleeve into the building.

May set in a floor slaps to waterproof pipes that are installed through the floor.

Applications for puddle flange instal at ions include: Foundations installs, Pools, Tank and Manhole instal at ions.

EPDM rubber is resistant to a wide range of acids and chemicals.
