Packaged Expanded Clay

fraction of 4-10 mmPackaged Expanded Clay- is expanded with the rapid firing of dark brown clay material cellular structure. Expanded clay is a unique ceramic porous gravel, which has the following properties:

  • lightness and high strength;
  • excellent heat and sound insulation;
  • fire resistance, moisture and frost;
  • acid resistance, chemical inertness;
  • durability;
  • eco-friendly natural material;

We offer expanded clay gravel fraction 8/20 mm, 4/10 mm, packed in a plastic bag with 50 liters (0.05 m ³). Shipment is made of expanded clay gravel in the rail and road transport.
