Installing urban benches on concrete requires proper anchoring to ensure safety and durability. First, position your bench exactly where you want it installed. Mark the anchor points through the bench's mounting holes onto the concrete surface using a marker. Move the bench aside and put on safety glasses before proceeding.
Using a hammer drill with a masonry bit matching your anchor size, drill holes into the concrete at your marked locations. The hole depth should slightly exceed your anchor length to accommodate debris. Clear the holes completely using compressed air or a vacuum.
Insert concrete anchors into the holes - wedge anchors work well for heavy benches while sleeve anchors provide good all-around performance. Position the bench over the holes, aligning the mounting holes with your anchors. Install washers and nuts, tightening until the bench is firmly secured without over-tightening.
For maximum stability, ensure all anchors are properly seated and the bench doesn't rock. Regular maintenance checks will help maintain security over time. This method creates permanent installations resistant to theft and movement while maintaining the aesthetic appeal of your urban space.
