Yes, you can bolt a park bench into concrete pavers, but it requires careful planning and the right technique to ensure a secure and lasting installation without damaging the pavers. Concrete pavers are a popular and attractive hardscaping material, but they are individual units placed on a compacted base, not a solid monolithic slab. This means the anchoring method must account for this segmented structure.
The most reliable approach is to use a through-bolt method with expansion anchors. First, you must carefully mark and drill holes through both the bench's mounting plates and the pavers beneath. It's crucial to use a hammer drill with a masonry bit sized specifically for your chosen anchors. To prevent the pavers from cracking, start drilling at a slow speed and avoid excessive pressure. Once the holes are drilled, clear all dust from them using a brush or compressed air. Insert the expansion anchor sleeves, then position the bench and secure it with the corresponding bolts and washers, tightening them to the manufacturer's specified torque.
A critical consideration is the base beneath the pavers. The anchors primarily gain hold from the paver itself. For maximum stability, especially for high-traffic public benches, it is often recommended to remove a few pavers at the installation site and pour a small concrete footing underneath. The bench legs can then be anchored directly into this solid concrete base, and the pavers are cut and replaced around it. This provides superior load-bearing capacity and prevents wobbling or loosening over time.
Always check local regulations or with the managing authority before proceeding, as there may be specific codes governing public furniture installation. Using the correct hardware—stainless steel or galvanized anchors to resist rust—and ensuring the pavers are fully settled and compacted will lead to a successful, safe, and durable bench installation that enhances your outdoor space for years to come.
