Park chairs are designed to withstand harsh outdoor conditions, including exposure to moisture, temperature fluctuations, and heavy use, which can contribute to mortar deterioration in concrete surfaces. Here’s how they help prevent this issue:

1. Material Selection: Many park chairs are made from corrosion-resistant materials like aluminum, stainless steel, or treated wood, reducing direct contact with mortar and minimizing chemical reactions that weaken concrete.

2. Elevated Design: Chairs with raised legs or bases prevent prolonged moisture retention on mortar joints, allowing proper drainage and airflow to reduce erosion.

3. Protective Coatings: Some chairs feature rubber or plastic feet that create a barrier between the metal or wood and the concrete, preventing abrasion and moisture seepage.

4. Proper Installation: Anchoring systems distribute weight evenly, reducing stress on mortar joints and preventing cracks or crumbling over time.

5. Regular Maintenance: Routine cleaning and inspections ensure chairs remain stable, preventing unnecessary pressure on mortar surfaces.

By combining durable materials, smart design, and upkeep, park chairs play a key role in preserving mortar integrity in outdoor spaces.
