Yes, urban benches can absolutely be bolted directly onto concrete, and it's actually the standard, most secure method for permanent installation in public spaces. However, it's not as simple as just drilling and screwing. Doing it correctly requires the right tools, materials, and technique to ensure a safe, stable, and long-lasting result.
The key is using concrete anchors. You cannot use standard screws or bolts. Instead, you need mechanical anchors like sleeve anchors, wedge anchors, or chemical anchors (epoxy-set studs). The process involves marking the precise mounting points on the concrete, drilling holes to the correct diameter and depth specified for your chosen anchor, clearing all dust from the holes (this is critical for grip), inserting the anchor, and then tightening the bolt that runs through the bench's mounting bracket. For heavy-duty public benches, chemical anchors often provide the strongest hold.
Always check the bench manufacturer's installation instructions first. The concrete must be in sound condition—not cracked or spalling. You'll need a hammer drill, a masonry bit, a vacuum or blower for cleaning holes, a wrench, and of course, the correct anchors and bolts. For liability and safety in public areas, this work is often best left to professional installers who can ensure a secure fit that withstands constant use and weather. Proper installation prevents wobbling, tipping, and potential injury, making the space safe and functional for everyone.
