A drive to maintain technology leadership while bringing new innovative products to customers quickly led Stoneway to SmartRock® Plus by Giatec.

The solution allows ready-mix producers to add value to their concrete mixes by giving their customers (contractors) the ability to see the strength of their concrete in real time.

Wireless sensors placed in the formwork relay in-place concrete temperature and strength results directly from the jobsite to the contractor’s phone using the free app supplied by Giatec. Here’s what they got:

  • Real-time data on the concrete curing process (temperature, strength, maturity)
  • Wireless connectivity that sent mix calibration data from jobsite to contractor’s mobile device
  • Free on-site, one-on-one training
  • Responsive customer support and professional sales materials from Giatec
