Integrating Tactile Ground Surface Indicators (TGSIs) into Tile Flooring: AS 1428 Compliance & Installation

02 December 2025

Tactile Ground Surface Indicators
Century Tiling ensures AS 1428-compliant tile flooring in Melbourne with tactile ground surface indicators installed for safety and accessibility. 

Tactile ground surface indicators are crucial safety features integrated into modern tile flooring to guide individuals with visual impairments. Their design and placement support compliance with AS 1428 standards, ensuring accessibility in public and commercial environments. Century Tiling implements advanced installation practices that uphold functionality, durability, and architectural aesthetics. 

Design Integration of Tactile Ground Surface Indicators 

Tile flooring design must balance safety, compliance, and visual harmony when incorporating tactile ground surface indicators. Proper layout ensures consistent direction cues and hazard warnings across transitional pathways. Materials such as stainless steel, polyurethane, and porcelain inserts maintain both slip resistance and long-term wear performance. 

Installation planning requires surface preparation and adherence to layout specifications before adhesive application. Grout joint alignment, thermal expansion, and substrate flatness must be carefully considered during installation to ensure full compliance with design and accessibility standards. Each tactile unit must be level and evenly spaced to maintain both accessibility and visual uniformity. 

AS 1428 Standards and Compliance Requirements 

Australian Standard AS 1428 defines the dimensional, luminance contrast, and placement criteria for tactile ground surface indicators to ensure accessibility for people with vision impairment. Adherence to these parameters promotes safe navigation in public and commercial environments while aligning with Australia’s universal design principles. 

Contractors must verify product certification, installation precision, and surface performance against the AS 1428 benchmarks before final approval. The Australian Building Codes Board’s Access to Premises Standards outlines detailed technical requirements and ongoing compliance measures to maintain safety and functionality throughout the system’s lifespan. 

Best Practices for Tile Installation 

Installing compliant tile flooring begins with selecting slip-rated materials suitable for the intended traffic load. Accurate measurement, dry layout, and adhesive selection prevent lippage and premature failure. Surface cleaning and grout sealing further improve longevity and appearance. 

Key installation considerations include: 

•  Surface Preparation: Achieve a level, contaminant-free substrate by grinding, cleaning, and priming as required to ensure superior adhesive bonding and long-term tile performance. 

•  Adhesive Selection: Specify high-performance, polymer-modified adhesives tested for tensile strength and flexibility to accommodate movement in high-traffic or heavy-load applications. 

•  Joint Control: Maintain uniform grout joint widths and alignment to minimise stress concentrations, prevent cracking, and enhance both appearance and durability. 

•  Curing Time: Adhere strictly to manufacturer-recommended curing periods to achieve full adhesive strength before subjecting the tiled area to mechanical load or moisture exposure. 

•  Final Inspection: Conduct comprehensive checks for slip resistance, tactile ground surface indicator alignment, and overall finish quality to confirm AS 1428 compliance before project handover.
