Tactile indicators & anti-slip
The tactile surface goes down to speak to blind pedestrians through the floor: blisters warn and stop; what a bar pattern means depends on the country and its orientation scheme — it can guide or warn of a hazard, so the scheme of the project country governs. The white cane and the sole read the texture; the tactile surface delivers the message without sight. It reads underfoot, contrasts and grips. The yellow surface also guides partially sighted pedestrians by luminance contrast. The tactile surface is used at dropped kerbs, heads of stairs, platform edges and building entrances.
- Blisters stop, bars guide
- Read by foot and by cane
- The bonded plate goes down without lifting the floor

Technical features
A tactile surface is not a warning sign but a marking read with the feet. The white cane and the sole detect the texture, so the message travels without sight. Choosing the right pattern is therefore a safety matter rather than an aesthetic one.
The two patterns say different things. A blister surface announces a hazard: before a crossing, at a platform edge, at a level drop. A bar surface draws the safe route and shows direction. Confusing the two gives the user wrong information.
Contrast matters as much as colour. The surface must differ enough in luminance from the floor around it to be seen, and ISO 23599 defines that difference numerically. Yellow is the most common choice because it separates from both dark asphalt and light tiling.
In refurbishment work the bonded plate is usually the most practical route. In new build, units integrated into the paving last longer. The bonded type goes down without lifting the floor; application and reopening time follow the adhesive instructions, and the job usually finishes without closing the area. A clean, dry surface decides the whole of the bond strength.
The right pattern in the wrong position sends the wrong message. The layout drawing takes five inputs: the project country’s scheme, the location (crossing, stairs, platform), the setback from the edge, the depth of the warning field and the route of the guidance path. These dimensions come from the country’s accessibility guidance, not from the product datasheet; the quotation carries the layout drawing with that guidance named.
Three properties are three separate test fields: profile dimensions, luminance contrast and slip resistance. None documents another — a plate with correct dimensions does not thereby pass the contrast test, nor a contrasting plate the slip test; each field speaks through its own report. Anti-slip coating is a separate product again: it makes a floor grip but carries no message a cane can read; the tactile job needs the patterned surface.

Installation
Where it is used
- Pedestrian crossing. At the dropped kerb the tactile surface announces the stopping point with blisters.
- Head of stairs. Before the first tread the tactile surface warning strip announces the level change.
- Platform and stop. The tactile surface draws the safe distance at the platform edge, readable with the feet.
- Building entrance and terminal. With its bar pattern the tactile surface carries the route from the entrance to the desk.

Standard reference
ISO 23599 defines tactile walking surface indicators for blind and vision-impaired people. There are two pattern types: an attention pattern for a hazard or decision point and a guiding pattern for direction.
The standard covers both the product and where and how it is laid. The right product in the wrong place does no good.
The Turkish market speaks of tactile surfaces through TS ISO 23599, TS 13536 and TS 13720; conformity is written with the supplier document. Contrast and profile dimensions follow the authority specification. Test results and certificates are shared with the report and the document.
Frequently asked
Blister or bar tactile surface — which one goes where?
They say different things. A blister surface says "stop here, there is a hazard": before crossings, at platform edges and level drops. A bar (guidance) surface says "travel this way" and draws the safe route. Confusing the two gives the user wrong information — and it is the most common mistake in this product class.
What colour should tactile indicators be?
Contrast matters more than colour: the surface must differ in luminance enough from the floor around it to be seen. ISO 23599 defines that difference numerically. Yellow is the most common choice in practice because it separates from both dark asphalt and light tiling. But the criterion is the luminance difference, not the colour name.
Can tactile indicators be added to an existing floor?
Yes. Bonded plates and individually fitted studs go onto existing pavement and tiled surfaces without lifting the floor. In new work, units integrated into the paving last longer. In refurbishment, the bonded type is the only practical way to finish without closing the area. The floor is ground before bonding. A plate bonded straight onto a painted or polished surface lifts with the first wheel that crosses it.
