If you’re planning to install a bench on a brick or paver surface, you’ll want it to stay put—especially in high-traffic or windy areas. Anchoring a bench on these materials requires slightly different methods than on concrete or wood, because brick and pavers are more prone to cracking or shifting. Here are the most reliable anchoring options.
1. Concrete Sleeve Anchors with Masonry Drill Bits
This is a heavy-duty approach. You drill into the brick or paver using a masonry bit, then insert a sleeve anchor (also called a wedge anchor). These expand as you tighten the bolt, creating a secure grip. Make sure the anchor depth is at least 1.5 inches into the base material, and always drill directly into the paver (not the sand joint) for maximum hold.
2. Adhesive Anchoring with Epoxy
For a less invasive option, use a two-part epoxy anchor system. Clean the hole thoroughly, inject epoxy, and then insert a threaded rod. This works especially well for bricks because the epoxy bonds chemically to the porous surface, providing strong tensile strength without the risk of cracking that mechanical anchors might cause.
3. Spike or Stake Anchors through Paver Gaps
If your pavers have regular gaps (like between concrete pavers or brick set in sand), you can use metal ground spikes that drive between the pavers. These anchors rely on the surrounding soil or gravel base rather than the brick itself. This is the least damaging method and works well for temporary or lightweight benches.
4. Surface-Mount Brackets with Heavy-Duty Adhesive
For benches that can’t be drilled (e.g., rental properties), use surface-mount brackets combined with polyurethane construction adhesive. Clean the paver surface thoroughly, apply adhesive to the bracket base, and press down. While not as strong as mechanical anchors, this can hold well for moderate weight loads.
5. Through-Bolt with a Backing Plate (for Paver Base)
If your pavers sit on a concrete slab or compacted base, you can drill through the bench leg, through the paver, and then through into the base material. Use a long bolt with a large metal washer or backing plate underneath (if possible). This ensures the bench pulls the paver into the sub-base rather than lifting it.
Important Tips:
- Always use a hammer drill with a carbide-tipped masonry bit.
- Seal the drilled holes with silicone before inserting anchors to prevent moisture from weakening the bond.
- For hollow bricks or thin pavers, avoid over-tightening mechanical anchors—use a torque-limiting setting.
- Test the bench by applying lateral force (pushing it side to side) to confirm stability.Choosing the right method depends on your bench weight, local weather conditions, and whether you can drill into the substrate. For most outdoor settings, a combination of epoxy anchors and sleeve bolts provides the best long-term hold.
