Since the formation of ASN Dale has been the principle Disability Access Consultant for a number of large corporate organisations, such as, Qantas Airways Limited, Fed Square and many of Victoria’s Local Governments.

Key Findings

Some key findings from Dale Sheppard’s Access® Tile product review are:

  • The Access® Tile is the ONLY Tactile Ground Surface Indicator product that ASN will specify / recommend.
  • It is the only TGSI product that doesn’t lift from the substrate causing trip hazards and maintenance issues.
  • Contains premium UV stabilisers, which are not on top of the tile but incorporated into the fibre-reinforced polymer compound.  This is imperative for Australia’s harsh climate and UV rays meaning that the Access® Tile will last much longer.
  • Fully Compliant to AS/NZS1428.4.1:2009.
  • The Access® Tile will not fade and blend into the substrate.
  • Additional grip / features beyond what’s required for a traditional Tactile Ground Surface Indicator.

Why are Tactile Ground Surface Indicators mandatory on footpaths and in buildings?

The practical need for accessible built environments is evident in the fact that 20% of Australians will experience a permanent or temporary disability over their lifetime.(1)  That’s an astounding four million people who require universal access in Australia.

Australian Federal Legislation, The Disability Discrimination Act (DDA), passed into law in 1992 making it unlawful to discriminate against any person with a disability.(2)  This law paved the way for many ingenious Australian innovations in this field, including Tactile Ground Surface Indicators (TGSI’s), and prepared the way for inclusion of Universal Access in many other codes and standards.

The use of TGSI’s, their design and their application, is founded on AS/NZS 1428.4.1.  ESP Australia uses this Australian Industry Standard as the benchmark to its TGSI Access® Tile product design, procedures and policies.

Tactile Ground Surface Indicator Facts


What do Tactile Ground Surface Indicators achieve for our footpaths and buildings?

TGSI’s assist persons with a temporary, permanent, full or partial vision-impairment to negotiate a built environment.(3)

They provide guidance and/or warning of an obstruction or hazard in any location where insufficient alternative or ‘natural’ tactile cue exists in a built environment. When combined with other environmental information, TGSI’s assist people who are blind or vision-impaired with their orientation.(4)

Why must we have Tactile Ground Surface Indicators in our buildings and on our streets?

The Australian Bureau of Statistics data revealed that in 2010, approximately 600,000 Australians were blind or living with some form of vision-impairment.(4) These persons who are classed as experiencing a vision impairment are mostly over 65 years of age.(5) According to Vision Australia, these figures are expected to climb to 1,200,000 by the year 2035.(6)



Who and what governs the use of Tactile Ground Surface Indicators within Australia?

Confused about which Tactile Indicator fixings you should be using to install ESP’s Access® Tile Tactile Ground Surface Indicators?  Not a problem, we’ve provided this article to simplify the process and hopefully answer some questions you may have.

Surface Applied Fixing Methods 

ESP recommend using either of the following fixing methods when installing Surface Applied Access® Tile Tactile Ground Surface Indicators:

  1. Screw + Plug Method
  2. Tek Anchor Method (Sleeve + Nail)

Both methods are recognised & suitable under ESP’s comprehensive warranty and will boil down to the preference of the qualified and certified installer.

Screw & Plug Method

This method is most common amongst Civil Contractors and Councils.

A question that we are often asked by first time users and civil contractors is ‘Can I install Tactile Indicators on asphalt?’

The simple answer is no, Tactile Ground Surface Indicators of any type should not be fixed directly to asphalt.  This is due to asphalt being an inherently unstable substrate, which is subject to movement caused by:

  • environmental or climate influences
  • uneven pavement surfaces
  • traffic loading
  • inadequate mixing
  • laying pavement over previous cracks
  • drainage deficiencies
  • construction deficiencies

However, if treated properly, TGSI’s can be installed safely and correctly to AS/NZS1428.4.1:2009 and the chance of movement and lifting can be eliminated.

Installing TGSI's On Asphalt

Correct / Preferred Method

ESP’s preferred method to properly install TGSI’s on to asphalt is to saw cut out the intended area that will require TGSI’s.  Once the asphalt area has been removed, it should be neatly filled in with concrete.  This will open up options to the installer, giving them the choice to either install ESP Cast In Place TGSI’s at the time the concrete is poured or retro fit ESP Surface Applied TGSI’s at a later date.

By adhering to this method and following the installation guides, ESP Australia will offer their full comprehensive warranty.

Image Below – The image below demonstrates the preferred method.  The neat cuts indicate where the asphalt has been removed and has been replaced with new concrete.  This eliminates the chance of ESP’s Access® Tile lifting and will ensure they perform to the highest standard for many years to come.

Installing TGSI's On Asphalt


Installing TGSI’s On Asphalt using Butyl Tape (Application)

Where removing asphalt and replacing with concrete is not an option, an alternative method is to increase the adhesion of the Access® Tile with the use of Butyl tape.  The tape replaces our regular method of adhesion (Sikaflex-11FC) and is installed to the underside of the tile around the perimeter.  Along with the supplied fixings, this will create the strongest bond possible.

Whilst this method will usually improve the adhesion to asphalt, it will not overcome the longer term instability of the substrate, and therefore ESP Australia is unable to offer a warranty for TGSI’s installed directly on to asphalt.

Installing TGSI's On Asphalt - Butyl TapeInstalling TGSI's On Asphalt


Calculating Butyl Tape Requirements

Butyl Tape is available in 15m rolls.

In order to calculate how much butyl tape will be required for your project please use the formula below:

Number of Tactile Indicators (300x600mm) X 0.6

Example – 16 x Yellow Warning TGSI (300x600mm) x 0.6 = 9.6 metres

Butyl Tape required = 9.6 metres
