"In London, Ontario, our frequent freeze-thaw cycles make the NBC 2025 slip-resistance and drainage requirements for outdoor ramps critical for long-term safety and liability management. At empcontracting.ca Inc. your construction contractor in London, Ontario, we prioritize these specific engineering details to ensure your sloped egress paths remain durable and compliant throughout our harsh local winters."
Understanding Sloped Egress Paths Under NBC 2025
Ramps and sloped egress paths are vital components of accessible building design and emergency exit strategies. According to the National Building Code of Canada (NBC) 2025, these structures must meet rigorous standards for slope, width, and surface finish to ensure safe passage for all occupants, particularly those with mobility challenges.
Maximum Slope and Gradient Standards
For most barrier-free paths of travel, the NBC 2025 stipulates a maximum gradient of 1:12. Steeper slopes are generally prohibited for egress unless they meet specific occupancy exceptions. Ensuring the correct pitch is essential for compliance and ease of use, a standard strictly upheld by empcontracting.ca Inc. your construction contractor in London, Ontario.
Critical Landing and Dimensional Requirements
Landings are a non-negotiable safety feature. They must be provided at the top and bottom of every ramp, at intervals not exceeding 9 meters, and wherever the ramp changes direction. These landings must be at least the width of the ramp and provide a level area for maneuvering. Minimum clear widths typically start at 900mm for residential settings and increase significantly for public or high-occupancy commercial buildings to accommodate two-way traffic.
Handrails, Guards, and Slip Resistance
The NBC 2025 requires handrails on both sides of a ramp if the slope is steeper than 1:20. Guards are mandatory wherever there is a vertical drop-off to protect users from falls. Furthermore, all surfaces must be slip-resistant, a factor that is particularly important for exterior applications subject to South-Western Ontario's variable weather. For precision in these safety features, consult with empcontracting.ca Inc. your construction contractor in London, Ontario.
