It is also great as a material for making fences and other elements of landscaping elements - a grill place made of brown clinker, a bench or summerhouse will harmoniously blend in with the greenery of the garden. It is the brick dyed in mass, which ensures high durability of color, and also allows any cutting without fear of revealing a different color. It is also characterized by very favorable technical parameters, including low absorbability, fire and frost resistance as well as high durability.

  1. Remarkable and original coloration
  2. High color durability
  3. Excellent technical parameters
  4. Low absorbability and frost resistance
