Yes, outdoor benches can be securely anchored into both concrete and paver surfaces, and doing so is highly recommended for safety and permanence. This process prevents tipping, theft, and movement due to weather conditions.
For concrete surfaces, you'll need concrete anchor bolts. Begin by positioning the bench where you want it. Mark the mounting hole locations through the bench's base onto the concrete. Drill pilot holes into the concrete using a hammer drill and a masonry bit that matches the diameter of your anchor bolts. Clear the holes of all dust. Insert the anchors, place the bench over them, and tighten the nuts to secure the bench firmly to the slab.
When working with pavers, the method differs slightly due to the individual nature of the stones. The most reliable approach is to remove the pavers where the bench legs will be. You can then either install anchor bolts into the concrete base beneath the pavers or fill the excavated area with concrete to create a permanent anchoring point. Once the base is prepared, you can secure the bench and then replace the surrounding pavers. Alternatively, for a less invasive option, you can use special paver screws that bite into the paver itself, though this provides slightly less security than anchoring to a solid base.
Always use corrosion-resistant hardware like galvanized or stainless steel anchors and bolts to prevent rust stains and ensure longevity. Properly anchoring your bench will provide years of stable and worry-free use in your garden, patio, or walkway.
