Cemstone Quality Standards
Cemstone aims to consistently provide first class products and service to our customers. We understand the detrimental effects of failing to meet these expectations and are dedicated to delivering quality every time.
In addition to our engineering staff, Cemstone has the largest group of certified Plant and Field Technicians in the upper Midwest. These skilled individuals are certified annually by the Iowa, Minnesota and Wisconsin Departments of Transportation for concrete and aggregate testing. In addition, many of these technicians are also certified by the American Concrete Institute for field testing of concrete. Our personnel serve in two capacities:
Plant Technicians
To ensure our concrete meets the expectations of our customers, our Plant Technicians:
- Monitor aggregate properties
- Perform physical testing of the plastic concrete
- Cast compressive and flexural strength samples
- Document admixture dosing
- Perform Department of Transportation Certification
Field Technicians
Once our product arrives on the project site, our Field Technicians:
- Measure and document the plastic proper ties of the concrete
- Adjust mixtures for air content and slump
- Oversee admixture dosing onsite
- Ensure our materials are meeting customer expectations
- Relay onsite mixture data for the ready-mix plant
