The TACTILE (patent n. 00237769) is a special language, imprinted on "Granitogres" fine porcelain tiles, able to guarantee greater autonomy and safety for the visually impaired when they have to move around. The modular elements in the flooring are arranged in easily understood informative codes, which give directional information and situation warnings through four different channels: plantar tactile sense manual tactile sense (with the white stick) hearing colour contrast, or, more specifically, luminance contrast (for the visually impared) The creation of systems aimed at helping mobility, through the ability to recognize places and sources of danger on the part of the visually impared, is a legal obligation, as underlined by art 1 od D.P.R. (Decree of the President of the Republic) 24 July 1996 n 503, which better specifies what was already formulated in the "Outline-law on the handicapped" of 5 February 1992 n. 104, relating to the elimination of architectural barriers. The "artificial" TACTILE guide system accompanies and complements the "natural" guide system which consists of the particular conformations of specific places (walls, pavements, ropes, hedges, flower beds, echo sounds ...) allowing the visually impared to orient themselves and move without need of further indications.

Italian standards

A number of articles contained in D.P.R. 503/96:

Art. 1.2.c "Architectural barriers are defined as: the absence of devices and signals which permit orientation and the ability to recognise places and sources of danger for all people and in particular for the blind, visually impared and the deaf".

Art 4 "Projects relating to public spaces and town planning schemes predominantly for pedestrian use must anticipate at least one accessible route able to allow for ... the use of services, social relations and enjoyment of the surroundings also for people with reduced or limited motory or sensory ability".

Art. 7.1 "For stairs and ramps are regulated by the provision contained in points 4.1.10 of the decree of the Minister of public works 14 June 1989, n. 236." The aforementioned Ministerial Decree states in art. "Stair ramps must be easily perceived also by blind 'people" and in art. 8.1.10 "... A signal on the floor (a strip of material which is different or in any case perceivable by blind people), situated at least 30 cm from the first and last stair, must indicate the beginning and the end of the ramp". 

Art. 13.3 "For external spaces belonging to the same buildings, the necessary requirement for accessibility is considered as met if there is at least one route for access to the building useable also by people with reduced or limited motory or sensory ability".

Basic codes

Straight Direction Code

t consists of a series of parallel grooves in the direction of movement, whose trapezoid shape and reliefs have been specially studied for best possible recognition, also using the white stick; it is created by using 2 tiles (art 30x30 Straight) which form a route with a width of 60 cm. The lenght of the route varies according to needs.

Stop-Danger Code

It consists of a series of spehrical segments arranged in a diagonal grid, sensed under the feet so as to make walking on them for any lenght of time uncomfortable. The signal consists of 2 tiles(art 20x20. 12 round and art. 20x20 13 round)laid alternatively (see figure) to form a depth of 40 cm and a minimum width of 60 cm.

Complementary codes

Compulsory L-Turn Code

It is a square of 60 cm. each side, divided into two triangles one of which contains grooves inclined at 45° with respect to the grooves in the Straight Direction Code; the second triangle contains the spherical segments which indicate an area of danger or an area not to be used.The tile size is 30x30 cm.The Code is created by installation of four tiles having three different surface finishes (art. 30x30 round, art. 30x30 diagonal/round and art. 30x30 diagonal).

T-Junction Code

It consists of a square-shaped bubbled surface, of 60 cm each side, made with 9 tiles (art. 20x20 studs).

Attention-Service Code

It consists of a strip of 40 cm depth, with a surface densely lined in a perpendicular direction with respect to the Straight Code grooving; the width in excess of the 60 cm of the straight route stands out in the direction of the service or the object adjacent to the route which is intended to be pointed out.The code is created by using tiles of 20x20 cm (art. 20x20 lines).

Code de Danger Franchissable

Il se compose d'une combinaison de deux codes, une bande de Code d'Attention-Service de 20 cm (art. 20x20 righe) immédiatement suivie d'une bande de Code Arret-Danger, elle aussi de 20 cm (art.20x20 12 tondi et 20x20 13 tondi alternés); il est appliqué à proximité d'une zone qui doit etre affrontée avec beaucoup d'attention (passage piétons ou grand escalier dans le sens de la descente).

Reccomendations for installation

The single articles composing the Tactile system are sold by the piece. To obtain a perfect final result, we recommend paying particular attention to installation, which must be done to professional standards, without joints and must ensure a perfect complanation of the tiles. Considering the relatively low thickness of the tiles, it is necessary to embed or stick the tiles on a suitable base, as required for any ceramic flooring (see installation instructions in the Granitogres Manual.

The Technical Handbook Granitogres can be requested free by sending a written request). The guided route for the blind in GRANITOGRES material represents the ideal solution for use in public spaces, such as stations, airports, the underground, shopping centres, squares, pavements, etc...

All, the tiles in the GRANITOGRES line, in fact, are resistant to wear and abrasion; they are totally frost resistant, non-slip (in the suitable surface) and easy to clean (in fact the greater the traffic to which the floor is subjected, the easier it becomes to clean). Considering the numerous possibilities for using the Tactile system, the designer can refer to the technical office of Casalgrande Padana, which is able to offer a complete consultancy service for the design and installation of the tiles. Our sales network, present in all the most important countries in the world, is also ready to offer any help needed.
