Sewerstream™  Puddle Flange with Hydrotite Seal - PN8 - SDR21
 
Sewerstream is dual-wall, co-extruded, high-density polyethylene pipe (HDPE) with a white inner jacket.
 
Puddle Flanges ensure a watertight and pressure-tight seal where pipes pass through concrete walls of any structure or building.
 
Designed for encasement in concrete, where PE passes through a structure (typically a concrete wall). Because PE is an ‘end to end system’ a PE puddle flange must withstand loads that exceed the ultimate tensile strength of the pipe, meaning Pipe fails first in a tensile pull to failure.
 
The concrete will not bond to the pipe and will usually shrink during curing, leaving an ingress path along the outside of the pipe allowing materials such as water, gases and hydrocarbons to pass through the structure or building.
