PY-003 Poka Yoka Flex Foundation Weep Screed™
#7 Foundation Weep Screed ¾” & 2” Flexible Leg
The PY-003 Poka Yoka Flex Foundation Weep Screed™ sets a new benchmark in foundation weep screed design with its innovative, mistake-proof installation system. Unlike conventional products, this flexible and self-adjusting solution eliminates guesswork, ensuring correct placement and alignment every time.
Its extended flange fully covers foundation gaps, delivering a clean, refined finish while maintaining full building code compliance. Engineered for durability and performance, the PY-003 promotes proper drainage at the foundation line, helping prevent moisture intrusion, insect infiltration, and long-term structural concerns.
As with all Poka Yoka™ solutions, installation is simplified into a single-step process. The installer secures the screed directly at the foundation line—no measuring, adjustments, or trial-and-error required. The result is a code-compliant, durable, and visually appealing finish that reduces installation time and costly errors.
