What are the challenges of bonding polyethylene to concrete bases outdoors?
Bonding polyethylene to concrete bases outdoors presents several challenges due to the material properties and environmental conditions. Polyethylene is a low-surface-energy plastic, making adhesion difficult without proper surface treatment. Concrete, on the other hand, is porous and can absorb moisture, further complicating the bond. Outdoor conditions like temperature fluctuations, UV exposure, and moisture can degrade adhesives over time. Selecting the right adhesive—such as epoxy or polyurethane-based solutions—is critical, but surface preparation, including cleaning and priming, is equally important. Without these steps, the bond may fail prematurely, leading to structural or functional issues in construction projects.
