Parking expansion joints: wheel loads and crossing conditions
A parking joint needs a traffic assessment as well as a movement check. Vehicle type, wheel contact, turning and braking conditions affect the selection and supporting detail.

Selection considerations
Identify the heaviest expected vehicles and whether emergency or service vehicles use the route. Mark turning zones, ramps and crossing angles. A joint on a straight passage may see different loading from a joint immediately beside a tight turn.
Compare any published load entry with its stated test or design conditions. Do not interpret a generic heavy-duty label as an approved axle or wheel capacity. Coordinate support edges, fixings, drainage and replaceable components. For an open parking deck, ask how the movement joint interfaces with the waterproofing system underneath the traffic surface.
Before you specify or order
- Describe vehicle and wheel conditions
- Map turning and braking zones
- Confirm load evidence and waterproofing interface

Common question
Is a heavy-duty name enough for a parking project?
No. The specified load case and movement requirement must be confirmed for the proposed system.
