Textured Surfaces

Textured surfaces, when used in various forms and applications, can be used to convey important information about the external and internal environment:

  • hazard warning (ie. at the top and bottom of steps)
  • directional guidance (ie. guidance around obstacles, finding a specific location)
  • presence of an amenity (ie. public telephone, information board, toilets).

External environment

  • Routes

  • Pavements

  • Stairs and steps

  • Car parks
  • Crossings

Internal environment - Building interiors

  • Approach to buildings
  • Stairs and steps

  • Lifts
  • Toilets
  • Danger warnings

Types of Textured Surfaces

Warning surfaces

Blister surface for pedestrian crossing points

  • Rounded flat topped blisters 5mm high. Found at controlled crossings only, this surface should be red. At uncontrolled crossings it should be buff or a colour other than red, so as to contrast with the surrounding area.

Corduroy hazard warning surface

  • Rounded bars run transversely, 20mm wide and 50mm from the centre of one bar to the centre of the next.

Platform edge (off street) warning surface

  • Comprises offset rows of flat topped domes 5mm high, spaced 60mm apart from centre to centre.

Platform edge (on street) warning surface

  • Comprises rows of oval shapes 6mm high with rounded edges.

Information/Warning surface

Segregated shared cycle track/footway surface and central delineator strip

  • This surface comprises a series of flat topped bars 5mm high, 30mm wide and 70mm apart. It is installed in the line of travel on a cycle path and across the line of travel on a footpath. The delineator strip is 12-20mm high, 150mm wide with sloping sides and flat top.

Amenity surfaces

Guidance path surface

  • This surface comprises oval bars with round ends 5mm high, 30mm wide running almost the width of the slab.

Information surface

  • To denote the location of amenities such as a public telephone, ticket office etc. Soft feel to surface.

The kinds of adjustments that you could make include:

Entrances, Interiors

  • Clear unobstructed routes must be provided throughout all the buildings. It is useful to create a path leading to the reception desk/bar counters etc. using contrasting floor finishes e.g. wood to carpet.
  • Recommend guests are able to differentiate between hot and cold water e.g. embossed taps.
  • Washing machines and dryers should have clear visible signs, preferably embossed on/off and hot/cold or tactile marking fluid.
  • Tactile (tactile marking and 'bumpons') and braille signs must be provided.


  • Lift locations must be clearly sign posted throughout establishment with guiding tactile markings and braille.
  • The floor level/location must be indicated on the wall adjacent to or just above the call buttons, and opposite the lift doors where possible, in large print, tactile and possibly braille (unless an audible floor level indicator is provided).
  • The emergency button must be easily identifiable in tactile and braille.


  • Top and bottom of ramp to be easily distinguished by contrasting texture and colour/tone e.g. a contrast strip.


  • Provision underfoot, of a timely warning, that there is a change in level is essential. The top and bottom of the stairs to include a warning surface.


  • Raised texture on paving is required when reaching an area that may be dangerous to a guest with visual impairment e.g. road junctions, service areas, water features etc.
