That's an excellent and very practical question! The good news is that in many cases, you can absolutely place a park bench on existing concrete, which can save significant time and cost compared to pouring a new foundation. However, it's not always as simple as just setting the bench down. The key factor is proper anchoring.
If the existing concrete slab is in good condition—structurally sound, level, and without major cracks—it often provides a perfectly suitable base. The critical step is securely anchoring the bench to the concrete. This is typically done using concrete anchors or bolts, which prevent the bench from tipping, sliding, or being stolen. Most commercial and public park benches are designed with flanges or base plates specifically for this type of secured installation.
A special foundation, like a new concrete footing, is usually recommended in a few specific situations: if the ground is unstable or slopes significantly, if there is no existing hard surface, or for extremely heavy or long bench designs that require extra support. Pouring a new pad ensures optimal weight distribution and longevity.
So, to answer directly: Yes, you can often use existing concrete. Just ensure it's stable, use the correct anchors for a permanent fix, and always follow the manufacturer's installation guidelines for your specific bench model. This approach combines convenience with safety and durability.
