Slip resistance testing: Adelaide’s NATA-accredited laboratory

Our NATA-accredited laboratory is run by skilled technicians who help solve problems and minimise the risk of trips and falls in your project. Our Adelaide-based slip testing team is certified to test to AS 4586:2013 (New Pedestrian Surfaces) and AS 4663:2013 (Existing Pedestrian Surfaces). We offer same-day slip testing* for Adelaide projects (we test Australia-wide).

Dimension stone testing and evaluation

Build confidence in your stone product and be assured of its fitness for use. Appropriate testing will determine the properties of the material and give you insight into thickness requirements for various paver formats for it to meet relevant industry standards or load requirements.

Finishes evaluation

The Finishes Evaluation Department encompasses slip resistance testing, stain resistance testing and sealer evaluation (among other relevant tests). When it comes to selecting a stone finish, there is far more than aesthetics to take into consideration. Our materials testing specialists can help you match the right products with your project, and create flawless surface finishes that are fit for purpose.

Ceramic tile testing

Whether you’re a designer, manufacturer, supplier or builder, our ceramic tile testing services provide reliable data and relevant insights for the benefit of your product or project. We provide comprehensive testing of ceramic tiles, including tiles for use on pedestals (pods).

Mineralogical examination

Stone Initiatives can facilitate testing to analyse the composition of any dimension stone. Our specialist technicians can perform a wide range of mineralogical tests to analyse your dimension stone for the presence of naturally occurring asbestos minerals, crystalline silica, or other potentially deleterious mineral components.

Facades and cladding surfaces

We provide independent testing of facade and cladding surfaces that utilise natural stone. Appropriate testing conducted by experienced technicians validates engineering calculations and assists architects, engineers and other stakeholders in ensuring that their proposed facade or cladding surface is fit for purpose.

Heritage services and mortar testing

Stone Initiatives specialises in the testing and evaluation of building stone and related materials such as historical coatings, mortar and cement products. Working alongside heritage architects, we carry out trials and perform a range of on-site and in-lab testing.

Failure investigation and expert witness services

We provide objective and independent Expert Witness services related to the selection, installation and use of stone products and related infrastructure. Our testing is backed up by an externally audited quality-assurance system, providing added confidence in court.

New construction

When dimension stone is used for building construction without full knowledge of its properties, problems such as cracking, spalling, staining and decay can occur. The natural variation and uniqueness that makes the stone so appealing can also bring about variability in physical properties. We can help.

How is stone evaluated?

At Stone Initiatives we spend time upfront learning about your project and the stone product to be evaluated. This important step gives us a solid understanding of what we are testing, at what thickness and size, for what and where it will be used, and what you’d like to achieve by using this particular type of material.

Representative sampling is very important – if we’re testing your product for a particular project, it’s best to test from a batch that is going to be used, at a relevant thickness and finish. Ship your samples to our NATA-accredited laboratory in Adelaide, or we can perform some tests on site in Adelaide, Sydney, Melbourne, Brisbane, across Australia and internationally.

Product evaluation experts

With decades of knowledge and experience in product testing and evaluation services, we’ve developed a suite of in-house testing methods to help determine fitness for use. These include various tests for strength, water absorption, slip resistance, abrasion resistance, stain resistance, durability and petrographic examination.

We also choose relevant tests from the range of Australian and International Standards that are most appropriate for your job, taking into account your specific project specifications. Once the testing has been completed, we work with you to ensure you understand what the test results mean and how you can use the results for the benefit of your product or project.

I have had many dealings with Stone Initiatives over the years and in all cases, Mark Milevski has taken time to guide me through the various forms of materials analysis that are performed on the sample we sent for testing. He explains the process and results sought for accurate findings on the material, so we can deliver a report to our client which I can confidently discuss with them. Mark has taken the time to assist in each case to suggest best locations for sample extraction and quantity or volume required on projects on which we are working, always heritage buildings. The reports delivered are detailed and comprehensive but done in a way that I and my clients can easily understand – layman’s language. These days it is almost a refreshing change to engage with someone in a highly specialized field who will provide the time and easy conversation.
