When installing street benches on concrete or asphalt surfaces, the anchor system you choose is critical for safety, stability, and longevity. The specific anchor system we use depends on the surface type and local requirements, but here is a clear breakdown of the standard solutions.
For Concrete Installation:
We primarily use expansion anchor bolts or wedge anchors made from galvanized steel or stainless steel. These bolts are inserted into pre-drilled holes in the concrete. As you tighten the nut, the anchor expands against the concrete, creating a strong mechanical hold. For heavier benches or areas with high foot traffic, we also offer epoxy adhesive anchors, where a chemical epoxy bonds the threaded rod inside the hole. This method is ideal for cracked concrete or where maximum pull-out resistance is needed.
For Asphalt Installation:
Asphalt is softer and less cohesive than concrete, so we recommend ground screw anchors (also called earth anchors) or surface-mounted plates with concrete ballasts. Ground screws are twisted directly into the asphalt and sub-base, providing a removable yet solid grip. For permanent installations, we sometimes pour small concrete footings beneath the asphalt and then use the same expansion bolts as concrete installation. Alternatively, heavy-duty base plates with concrete blocks can be bolted on top of the asphalt without drilling into the surface itself.
Common Features Across Systems:
- All hardware is corrosion-resistant (hot-dip galvanized or stainless steel).
- Anchor patterns are pre-drilled on our bench bases to match standard spacing.
- We include tamper-resistant security bolts for public spaces.
In short, we use expansion anchors for concrete, ground screws for asphalt, and offer epoxy or concrete footing options for heavy-duty needs. Our goal is to match the anchor system to your specific site conditions, ensuring your benches remain firmly in place for years to come.
