What are the load-bearing limits for concrete outdoor sofa bases?
Concrete outdoor sofa bases are popular for their durability and modern aesthetic, but understanding their load-bearing limits is crucial for safety and longevity. Typically, a well-constructed concrete base can support 500 to 1,000 pounds (227 to 454 kg) depending on the mix design, thickness, and reinforcement. Factors like concrete strength (measured in PSI), curing time, and environmental conditions (e.g., freeze-thaw cycles) also impact capacity. For heavy-duty use, opt for high-strength concrete (3,500+ PSI) with steel reinforcement. Always consult an engineer for custom designs to ensure stability and compliance with local building codes. Proper maintenance, like sealing, further preserves load-bearing performance over time.
