When installing park benches on paved surfaces like concrete or asphalt, proper anchoring is crucial for safety, stability, and longevity. The primary goal is to prevent tipping, theft, or movement, ensuring the bench remains a permanent and secure fixture. Here are the most effective anchoring options.
For permanent installation on concrete slabs, concrete anchors are the standard choice. This typically involves using expansion anchors, sleeve anchors, or chemical anchors. The process requires drilling holes into the pavement, inserting the anchor, and tightening it to secure the bench's base plates. This method offers exceptional shear and tensile strength, making the bench highly resistant to lifting or shifting.
Another reliable option is surface-mounted anchoring with bolt-down feet. Some bench designs come with integrated flanges or feet with pre-drilled holes. These are positioned on the pavement, marked, and then secured using concrete anchors as described above. This provides a clean, direct connection.
For situations where drilling into the pavement is not permitted or desired, heavy-duty surface plates can be an alternative. These large, weighted steel plates are bolted to the bottom of the bench legs. While not as permanently fixed, their significant mass can deter casual movement or tipping, though they are less effective against determined theft.
Key considerations include checking local regulations and utility lines before drilling, using corrosion-resistant stainless steel or galvanized hardware, and ensuring the bench is level during installation. For the most secure and professional result, consulting with or hiring a contractor experienced in public furniture installation is often recommended. Proper anchoring protects public investment and ensures visitor safety for years to come.
