C3S, Inc.

Builds the quality of concrete ingredients upfront into projects to improve the lifespan of structures and reduce ongoing maintenance costs.

• Sourcing and Qualifying

  Assists with identifying and monitoring sources of good aggregates and cements during project planning stages.

• Concrete and Cement Evaluation

  Evaluates cements and aggregates on capital projects for compliance to project specifications and durability requirements.

• Alkali-Silica Reactivity Testing

  Performs petrographic tests and analysis to identify potential alkali-silica reactivity (ASR) in concrete aggregates.

• Mineral Admixture Optimization

  Selects and optimizes mineral admixtures to improve concrete placement in varying weather conditions and enhance durability.

Quickly responds to defects or recurring problems during construction, such as low compressive strengths, cracks, and surface scaling.

• Concrete Strength Testing and Evaluation

  Conducts concrete strength testing, mix design confirmation, and in-place strength evaluations.

• Field Inspection and Quality Control

  Provides progress reports, concrete batch plant inspection, air content tests using a Type-B Meter, slump tests, and pier observations.

• Rebar Inspection and Layout Verification

  Performs layout verification and rebar cage inspection for compliance with design documents prior to concrete placement.

• Construction Monitoring

  Oversees concrete construction, reviews construction documents, and provides progress reports with recommendations to correct deficiencies.

Minimizes maintenance costs and prevents costly repairs by identifying the underlying causes of structural problems prior to extensive repair.

• Condition Assessment

  Performs visual inspections and non-destructive testing, such as Ultrasonic Pulse Velocity (UPV), to evaluate the condition of concrete, rebar, and reserve capacity.

• Forensic Investigation

  Identifies general distress in concrete, cementitious grout, and other construction materials using field and laboratory testing.

• Petrographic and Chemical Analysis

  Utilizes petrographic evaluation, chloride ion content determination, and scanning electron microscopy (SEM) to analyze concrete deterioration.

• Litigation Support

  Provides expert witness testimony and forensic evaluations of damaged structures for construction litigation cases.
