Meet Brendan Sheedy

Founder & Lead Slip Resistance Consultant
Brendan Sheedy is the founder of Zerofal and a nationally recognised specialist in slip resistance testing and surface safety. With years of hands-on experience across commercial, industrial, and public environments, Brendan works closely with builders, manufacturers, facility managers, and safety professionals to assess and verify surface slip performance.
His work focuses on practical risk reduction. Using NATA-aligned testing methods and industry standards including AS 4586 and AS 4663, Brendan helps clients understand how surfaces actually perform in real-world conditions — from new product certification through to post-installation compliance testing.
Brendan is known for his practical, collaborative approach. Rather than simply issuing results, he works with clients to interpret testing outcomes, understand compliance obligations, and reduce slip risk across their sites.
Don’t Wait for Handover Week to Book Your Lab Test

Late booking of AS 4586 testing can delay certification. Testing the final surface system is critical.
Retail Entries: The First 3 Metres Are the Highest Risk Zone

Most retail slip incidents occur at entry thresholds. Annual testing provides defensible documentation.
Autumn Changes Surfaces. Have You Checked Yours?

Autumn moisture exposes surface performance drift. Learn why reassessment under AS 4663 strengthens defensibility.
The Five Moments You Should Always Re-Test a Floor

Learn the five moments when re-testing slip resistance matters most — and how timing reduces risk more effectively than routine checks.
When Should a Product Be Re-Tested? The Question Manufacturers Get Wrong

Learn when flooring products should be re-tested for slip resistance and why one result rarely covers a full product range.
Why January Is When Latent Slip Risk Shows Up in Commercial Buildings

January maintenance and reopening cycles can increase slip risk. Learn why early-year verification matters for commercial buildings.
What Changes a Floor’s Slip Risk Over Time (Even If Nothing Looks Different)

Slip resistance changes over time due to cleaning, wear and moisture. Learn what drives risk drift and how to manage ongoing floor safety
Colour, Grit and Surface Finish: How Subtle Differences Change Slip Ratings (AS 4586:2013)

Colour, grit and finish change slip resistance. Learn why P-ratings vary across tile ranges and coatings
Why One Slip Test Isn’t Enough for Product Lines (AS 4586:2013)

Slip resistance varies across colours and finishes. Learn why one AS 4586 test cannot certify an entire product line.
