Iron-silicate stone in road construction

Stone particles made of iron-silicate can be used as an anti-freeze layer and ballast as well as pavement beds in road construction.

Special advantages:

  • Very good load-carrying capacity
  • Very good resistance to frost
  • Good water permeability

Our stone particles fulfil the requirements of TL Gestein-StB 04 / TL SoB-StB 04 and are correspondingly certified and quality controlled by:

  • Works production control (WPC)
  • External quality audits
