Slip resistance testing
in Brisbane.

What a pendulum test involves on an existing floor

Most Brisbane enquiries are about a floor that is already down — tile, stone, vinyl, sealed or polished concrete, outdoor paving, or a surface that has been coated or treated since it was laid. That is existing-floor slip resistance testing: Premrest comes to the property, tests the locations in the brief, and records how those pedestrian surfaces perform on the day.

The instrument is a pendulum tester. The operator works on the nominated spots, notes the surface and the conditions, and takes the readings the method requires. Access is arranged around how the building actually runs, so a lobby, kitchen, amenities block or outdoor path does not have to be closed for a whole morning. Barricade time at each location is usually short.

AS 4663:2013 addresses measurement of existing pedestrian surfaces. That is the standard this kind of site visit sits against. It is not a laboratory classification of unused material, and it is not an “anti-slip test” of a coating in the abstract — it is a slip resistance assessment of the walking surface people are using now. Tell Premrest the finish, any treatment or cleaning regime, and why the test has been requested, so the scope matches the floor rather than a generic label.

Wet versus dry testing

Wet floor slip testing and dry testing answer different questions. Wet pendulum testing assesses slip resistance under recorded wet conditions. That is the relevant state for entries that take rain, bathrooms, change rooms, pool surrounds, wash-down floors and outdoor circulation that stays open through a Brisbane storm. If people use the surface while it is wet, a dry reading on the same tile does not describe that use.

Dry testing may be specified where the surface is used dry, or where a project brief asks for both states. Say so in the enquiry. “Test the floor” is not enough: list each area and whether it is normally wet, dry, or wet only in weather or during cleaning. The method in the quote then follows the way the property is used, instead of a one-size visit that misses the condition that matters.

For a working commercial building whose wet rooms, storm-soaked entries and outdoor paths have to stay in service, see slip testing for commercial wet areas. The Brisbane wet-area checklist helps you describe drainage, weather exposure and access before you enquire.

What the written report contains

The deliverable is a slip resistance testing report — a written record of the visit, not a certificate that the floor is safe or that the building complies. Confirm the report requirements with Premrest when you book. A useful report typically includes:

• The locations assessed, so a later reader can find the same spots.
• The test method used at each location.
• The conditions recorded on the day, including whether the surface was tested wet or dry.
• The results for those surfaces and conditions.

If an insurer, consultant, superintendent or project team has asked for particular information on the page, include that request in the enquiry so the report can be scoped to it. The findings sit with the surfaces and conditions assessed. They do not guarantee a floor will never be slippery, and they do not settle every aspect of a property’s compliance. Water, contamination, footwear, wear, cleaning and how people use the space still matter after the team has left.

Who typically needs a slip resistance assessment

Businesses ask for slip testing when a floor is already in use and someone needs a current measurement: after a treatment, after an incident, before a refurbishment, or because an insurer or consultant has asked for one. The brief is usually a short list of pedestrian surfaces and the reason the reading is needed.

Property managers, facilities teams and body corporate managers tend to book the same kind of visit across a portfolio or a common-area building — entries, amenities, outdoor paths and other floors the public or residents walk every day. Slip testing for property managers works best when the enquiry names each surface, how it gets wet, and the access windows the site can actually give.

Builders meet the request in two different places. While a tender is still being priced, the documents may mix an AS 4586 slip rating on new material with on-site testing of floors already in the building. That pricing question is set out on slip testing for Brisbane builder tenders. Once the floor is installed and someone wants a pendulum test before practical completion, occupancy or handover, the brief is a site visit to that surface — see slip testing before handover or practical completion.

Existing surfaces and new materials

AS 4663:2013 addresses measurement of existing pedestrian surfaces. AS 4586:2013 addresses classification of new pedestrian surface materials. The appropriate standard depends on what is being assessed. A classification on a supplier sheet describes unused product; it should not automatically be treated as a current measurement of a floor that has been laid, grouted, sealed, cleaned and walked on.

Start with the purpose of the test. Are you assessing a floor already in use, reviewing a recent treatment, or working to a project specification? Share that reason, any previous findings, and the clause or written request if there is one. Premrest can then confirm which surfaces and methods belong in the scope, instead of quoting a generic “slip test” line that does not match the documents.

Before the visit

• List each surface and its location within the property.
• Describe usual wet or dry conditions and known concerns.
• Provide specifications, previous reports and treatment details where available.
• Confirm access, operating hours and who will meet the testing team.

Use the Brisbane wet-area checklist to prepare your site brief.
