That's an excellent question! Securing a public bin properly is crucial for safety and to prevent theft or tipping. Here's the most reliable method, similar to what professionals use.
You'll need a hammer drill, a masonry drill bit sized for your anchors, a wrench, concrete anchors (like wedge anchors or sleeve anchors), the waste bin with a pre-drilled base flange, a vacuum, safety glasses, and gloves.
First, position the bin exactly where you want it. Mark the anchor hole locations through the bin's base holes onto the concrete. Move the bin aside. Now, put on your safety gear. Using the hammer drill and correct-sized bit, drill straight down into the concrete at your marks. The hole depth should slightly exceed the anchor length. Clear all dust from the holes with the vacuum—this is critical for a strong hold.
Place the bin back over the holes. Insert the concrete anchors through the bin's flange and into the holes. For wedge anchors, as you tighten the nut with your wrench, the anchor expands and locks itself permanently into the concrete. Tighten everything firmly until the bin is rock-solid.
The key is using the right concrete anchors and ensuring clean, deep holes. This creates a permanent, vandal-resistant installation that will keep the bin securely in place for years. Always check local regulations, as some areas may have specific requirements for public fixture installations.
