That's a great question! A loose trash bin rolling into the street or getting stolen is a real hassle. Securing it to concrete is simpler than you might think. Here are the most effective methods.
The most permanent and sturdy solution involves using concrete anchors. You'll need a hammer drill with a masonry bit, concrete sleeve anchors or wedge anchors, and a metal bracket or a length of heavy-duty chain. First, position your bin where you want it. Mark drill points on the sidewalk through the bracket or for the ends of your chain loop. Drill into the concrete to the required depth, clear the dust, insert the anchors, and tighten them down to secure the bracket or chain. Finally, use a sturdy lock or carabiner to attach the bin to the anchored bracket or chain. This method is excellent for high-theft areas.
For a less invasive, tool-free approach, consider heavy-duty straps or bungee cords designed for anchoring. Look for outdoor-rated straps with a loop on one end. Place a large, heavy sandbag or a purpose-made anchor weight next to the bin on the sidewalk. Loop the strap around the base of the bin and through the handle of the weight, pulling it tight. Alternatively, you can loop the strap around a sturdy, immovable object like a fence post or railing leg if one is nearby. While not as theft-proof, this greatly prevents tipping and rolling.
A couple of quick tips: Always check local ordinances or with your landlord before drilling into public or rented property sidewalks. For a cleaner look with the chain method, you can use a plastic chain cover. Regularly check your anchoring point for wear, especially if using straps.
Choosing the right method depends on your need for permanence versus convenience. A simple strap and weight system solves most rolling issues, while concrete anchors offer maximum security for peace of mind.
