COMCON® CDR sidewalk tiles are smooth, measure 255 x 255 mm, and are 30 mm thick.
These tiles are can be produced in any colour, and are normally produced in white, black, dark grey and brown. Colours are achieved through the colour of the filler and binder used, and/or the use of permanent colours, mainly inorganic. Standard pigmentation ensures colour permanence even outdoors, and does not require any special maintenance.
COMCON® CDR tiles are installed using dry lime or cement-lime mortar 3 to 5 cm deep, spread on a well-compacted substrate. These tiles are intended for foot traffic. A project engineer shall assess installation suitability for other load levels and applications.
