What are Post Protector™ Barrier Sleeves?

Post Protector™ is an advanced barrier sleeve designed to protect 6x6 wood posts—like pressure-treated lumber and cedar—from direct contact with soil or concrete. They prevent decay and rot by eliminating two major culprits: moisture and microbial activity.

These innovative sleeves use landfill-liner technology, delivering up to 449 years of ground-tested protection. Lightweight, flexible, and tough, Post Protector™ barrier sleeves are a game-changing solution for anyone building a pole barn, deck, fence, or retaining wall.

How does a Post Protector™ Sleeve work?

Decay happens when three ingredients are present: Oxygen Moisture Temperatures between 40–100°F

Post Protector™ acts as a barrier system that breaks this decay formula by removing soil-to-wood contact—blocking out moisture and soil-dwelling microbes that feast on wood fiber. [Source: postprotectors.com]
