Post-Incident Slip Resistance Testing

Independent, NATA-accredited testing of the floor where a slip or fall happened. We measure the surface to AS 4663 and report the result and classification for each area, so the people handling the matter are working from facts.

What It Is

An independent record of the floor's condition

After a slip or fall, the first question is usually whether the floor met the slip resistance it should have. Post-incident testing answers that with a measurement, not an opinion. Our technician attends the site, tests the area where the incident happened and the comparable areas around it, and reports the measured result and P classification under our NATA accreditation.

Sliptest Australia is an independent testing laboratory. We do not sell flooring, coatings or anti-slip treatments, so the result carries no commercial interest. Property owners, insurers, claims managers and legal teams use our reports as the factual record of the floor.

How It Works

From incident to NATA-endorsed report

Tell us about the incident

Site address, the area involved, the incident date and who the report should go to. We confirm the scope and the test locations before we attend.

Site attendance

Wet pendulum testing to AS 4663 at the incident location and comparable areas nearby, with Slider 96 for shod areas or Slider 55 for barefoot areas. Each location is photographed and measured.

Conditions recorded

Surface type, finish, contamination, cleaning state and any known changes since the incident are noted, so the result can be read in context.

Factual report

Measured BPN, P classification and a comparison with the classification typically recommended for that location. Endorsed under NATA accreditation No. 15374, usually issued within 24 hours of the visit.

When You Need It

Situations where we are called in

Public liability claims, a customer or visitor falls in a shopping centre, hotel, restaurant or office foyer
Workplace incidents, an employee falls and the employer needs to understand the floor's condition
Strata and body corporate, falls on pool decks, lobbies, stairs and common areas
Council and public spaces, footpaths, aquatic centres, libraries and transport hubs
Insurer and claims manager requests, an independent measured result for the claim file
Builder and defect matters, whether a new surface met its specified classification
We report the measured facts of the test. We do not provide expert opinion or act as an expert witness. Where a matter needs expert opinion, legal teams engage their own expert and use our NATA-endorsed results as the factual basis.

Common Questions

Post-Incident Slip Testing FAQ

As soon as practical. Cleaning, wear and treatments change a floor over time, so testing close to the incident date gives the most representative record. Tell us the incident date when you book and we will prioritise the visit.
