When working on paved or structurally reinforced sites, traditional digging methods for fence post foundations are often not viable. Chain wire fencing with bolt-down footplates provides an efficient, code-compliant, and surface-friendly option for both permanent and temporary applications on hard ground such as concrete, asphalt, and stone slabs.
The layout process begins with a site assessment—identifying expansion joints, underground utilities, and substrate strength. Each post is mounted to a laser-cut steel footplate designed to spread loads across surface area. In a UK data center, fencing was laid out with 100mm offset from drainage channels and still allowed full tensioning of chain-link fabric.

Anchor type depends on substrate hardness. On newer concrete, expansion bolts meet ASTM E488 pullout strength criteria. On older surfaces, resin-injected chemical bolts provide superior grip. ISO 21940 also recommends vibration resistance in dynamic environments like near equipment yards.

Footplates are typically square or rectangular with four-bolt arrangements. Fence posts include pre-drilled flanges for seamless bolt-down attachment. Mesh fabric is tensioned using brace bands and end rail fittings. The ASCE 32-01 urban fence standard supports bolt-mounted post systems in densely paved environments.
Drilling into pavement risks cracking without proper prep. Anchor zones should be cleaned, leveled, and primed with epoxy if surface degradation is present. Fence layout must also consider water flow—footplates should be installed away from slope downs or expansion seams. In Osaka, bolt-down fencing was installed along rooftop HVAC decks with water deflectors integrated into each base plate.

A major courier hub needed a fencing solution that avoided pavement cuts on its new concrete yard. Using 10mm epoxy-anchored bolts, they installed 2.1m-high chain wire fencing with anti-ram posts every 10m. The setup included access control gates also mounted via steel baseplates. Final inspection confirmed compliance with ISO 21932 and ASTM anchoring criteria.
