SLIP RESISTANCE FOR RAMPS

slip resistance for ramps

NCC 2016 requires slip resistance ratings for new construction of ramps. The pendulum or ramp rating testing method is used to determine the grip on incline surfaces. The the ramp surfaces must pass both WET and DRY slip resistance requirements to comply with the construction code.

Given the broad range of test methods available deciding how to best evaluate the safety of your pedestrian surface can be confusing.  Correct test method selection depends on a range of factors including:

Is the surface unlikely to become wet? 

The area must be surveyed for occasional water such as water from umbrellas, beverage spills etc. Once the surface has been assessed the the risk will determine the correct solution to be employed. Lift lobbies and corridors are not generally exposed to water contamination and are therefore often tested using a dry Floor Friction Tester . 

HOW IS SLIP RESISTANCE MEASURED?

  • There are five different approved methods of measuring slip resistance
  • Wet Pendulum
  • Wet Pendulum and Dry Floor Friction
  • Dry Floor Friction
  • Wet/Barefoot Ramp
  • Oil-wet Ramp

Each type of test is specific to the type of installation location and the exposure to the elements.

There is no direct correlation between the results obtained from each method. More slip resistant surfaces should obtain higher ratings across all methods used.

External ramps are subject to additional issues with dust, oils from overhanging trees and general contamination like oils from vehicle exhausts and spills etc.

APPROPRIATE TREATMENT OF RAMP SLIP RESISTANCE

  • Minimising detergent residue build up or other contaminants.
  • Acid etching
  • Increasing surface texture.
  • Coatings and sealers
  • Surface coatings and penetrative types.
  • Surface texture
  • Coatings, etchants, sandblasting, shot blasting, etc.
  • Surface replacement
