The NRMCA Pervious Concrete Contractor Certification program ensures that knowledgeable contractors are selected to place the product and thereby minimize the chance for failure. There are three levels of certification:
- A Pervious Concrete Technician is a person who demonstrated knowledge by successful completion of a written exam about proper procedures to place, compact, finish, edge, joint, cure and protect pervious concrete pavements, but who lacks the requisite field experience to qualify as a pervious concrete Installer or Craftsman.
- A Pervious Concrete Installer is a person who has demonstrated the ability to place, compact, finish, edge, joint, cure and protect pervious concrete pavements and has documented a limited project-based field experience in placing pervious concrete.
- A Pervious Concrete Craftsman is a person who has deomonstrated the ability to place, compact, finish, edge, joint, cure and protect pervious concrete pavements and has documented a higher level of field time-based experience in placing pervious concrete.
