Pervious Concrete Contractor Certification

Important Update: Pervious Concrete Contractor Certification
The NRMCA Pervious Concrete Contractor certification program is temporarily on pause as it is being transferred from NRMCA to ACI. Additional information will be posted on its new page, ACI Certification Programs.
Key Transition Details:
  • Effective April 1, 2026: Program servicing will officially transfer from the National Ready Mixed Concrete Association (NRMCA) to the American Concrete Institute (ACI).
  • Current Status: ACI is currently finalizing the materials, processing infrastructure, and reporting systems required for this handoff.
  • WACA Sessions: The Washington Aggregates & Concrete Association (WACA) will resume offering certification sessions immediately following the April 1st transition date.
What This Means for You:
  • Currently Certified Individuals: Your certification remains valid. You only need to recertify when your current expiration date is reached.
  • New Applicants: Once sessions resume, you will be provided with updated application forms and materials as issued by ACI.
