How do you address thermal expansion in concrete outdoor sofa joints?

Thermal expansion in concrete outdoor sofa joints can lead to cracking and structural damage if not properly managed. To address this, follow these key steps:

1. Use Expansion Joints: Incorporate flexible expansion joints between concrete sections to absorb movement caused by temperature changes. Materials like silicone or polyurethane sealants work well.

2. Proper Spacing: Leave adequate gaps (typically 1/4 inch per 10 feet of concrete) to allow for expansion and contraction.

3. Durable Materials: Choose high-quality, weather-resistant concrete mixes and reinforcing fibers to minimize cracking.

4. Regular Maintenance: Inspect joints annually and reseal them as needed to prevent water infiltration and further damage.

By implementing these strategies, you can ensure your concrete outdoor sofa remains durable and visually appealing for years.
