When it’s enough
- Marking a walkway or a parking edge, guiding traffic, light knocks.
- Slabs you can’t core: parkade decks, slabs with in-floor heat or post-tension cables, tenant spaces where the landlord won’t allow it.
- A shallow-mount crash-rated system, where the maker has tested exactly that mounting.
When it isn’t
A plain base plate on four anchors can shear off under a car that a cored or embedded post would stop. In front of glass, people or gas meters, use a core-drilled or embedded bollard, or a rated shallow system.
