Concrete Tank Stations:
Fresh Concrete in Small Quantities from 0.15 m³

With a promix concrete tank station, your customers can dispense fresh concrete in small quantities from 0.15 m³ themselves – fully automatically via QR code control. Whether single-use ticket or customer card: the entire transaction is processed through the integrated self-service terminal.

Self-Service Payment Terminal:
Pay for Building Materials Cashless 24/7

The promix self-service payment terminal expands your building materials facility with a cashless sales channel. Customers order and pay for concrete or bulk materials independently – by EC card or Mastercard, around the clock. For you as the operator, manual cash handling is completely eliminated.

Bulk Material Dispenser:
Fully Automatic Sale of Sand, Gravel and Chippings

With the promix bulk material dispenser, you sell sand, gravel, chippings and aggregates fully automatically – unmanned at the dispensing point. Customers select product and quantity, pay by ticket or self-service payment terminal and take the goods directly with them. The system operates independently of your opening hours.

Consulting & Planning:
Site Selection, Financing, Commissioning & Maintenance

From site selection through financing to commissioning, we accompany you through every step. After startup, individual maintenance concepts and spare parts are available. Our service technicians are deployed throughout Germany from Lauchringen, Recklinghausen and Cottbus – and upon request throughout the DACH region as well as in Poland and France. Planning, production and service come from a single source.
