Pervious Concrete Contractor Certification

Important Update: Pervious Concrete Contractor Certification
The NRMCA Pervious Concrete Contractor certification program is temporarily on pause as we transition to a new provider.
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.
