Rectifying Trip Hazards from Differential Floor Heights
Uneven transitions between floor finishes (e.g., tiles to carpet) are a leading cause of trips, especially in accessible paths.
Under the current AS 1428.1:2021 (referenced in NCC 2022 Amendment 2 and Premises Standards since July 2025):
Vertical changes ≤5 mm: Acceptable with smooth transition (tolerances allow minor bevel/rounding on edges to reduce trip risk).
Changes >5 mm but ≤13 mm: Must be bevelled with a maximum slope of 1:2 (≈27°), applied to the higher edge.
Changes >13 mm: Treated as a step or ramp — require full ramp compliance (e.g., ≤1:8 gradient, landings, handrails if needed).
Quick rectification steps:
Grind/plane down high spots for ≤13 mm differences.
Install durable bevel strips or tapered edges (1:2 max).
Add threshold ramps for larger changes (if doorway allows).
Re-level or replace finishes for permanent flush results.
Always measure finished floor levels — subfloor tolerances often create hidden non-compliance.
Fixing these small hazards boosts safety for wheelchair users, low-vision individuals, and everyone — preventing incidents and retrofit costs.
