Securing an urban bench to a concrete slab is crucial for safety, durability, and preventing theft or vandalism. The best method involves a combination of the right hardware and proper technique. First, you'll need heavy-duty anchor bolts, such as wedge anchors or sleeve anchors, specifically designed for concrete. Epoxy adhesive anchors offer an even stronger, chemical bond for high-security locations.
Begin by positioning the bench's base plate or mounting feet on the slab. Mark the drill holes accurately. Using a hammer drill and a carbide-tipped masonry bit, drill holes into the concrete to the depth and diameter specified by the anchor manufacturer. It's vital to blow out all concrete dust from the holes to ensure a tight fit. Insert the anchors, then place the bench over them and tighten the nuts with a torque wrench, ensuring the bench is level and stable. For maximum security, consider using tamper-resistant bolts that require special tools to remove. This permanent mounting solution withstands heavy use and deters theft, ensuring your public seating remains safely in place for years to come.
