Tactile warning domes
for outdoors
installed in situ

In public spaces TG Lining installs tactile warning domes to make blind and visually impaired people aware that they are approaching potentially hazardous situations such as street crossings or staircases.

These warning domes are installed in accordance with national directives and standards and are applied directly to the substrate in situ. This provides superb adhesion to virtually all types of substrates without the need for drilling, gluing or sawing.

Domes can be walked on after approximately 12 hours at a minimum processing temperature of 10°C and do not require any post-processing. Areas are kept accessible to pedestrians by making use of covering plates, even during the execution of our works.
