Pervious Concrete Contractor Certification Program

 

Program Summary

 

The goal of this certification program is to ensure that knowledgeable contractors are selected to place the product and thereby minimize the chance for failure.

The program is designed to be administered locally by local sponsoring groups in conjunction with planned training sessions or demonstrations of pervious concrete placement. NRMCA provides certification exams and performance evaluations to approved local sponsoring groups for administering the certification. For the current list of local sponsoring groups, click here.

 

Three levels of certification are available:

  1. A Pervious Concrete Technician is a person who demonstrated knowledge 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.

  2. 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.

  3. A Pervious Concrete Craftsman is a person who has demonstrated 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.

Scope and Knowledge 

 

The program requires knowledge in the following areas of concrete construction:

  1. Basic concrete technology

  2. Pervious concrete materials and mix proportioning

  3. Proper use of tools and equipment

  4. General design principles of pervious concrete pavements

  5. Pervious concrete construction

  6. Maintenance and troubleshooting

NRMCA Publication #2PPCRT Text Reference: Pervious Concrete Contractor Certification will serve as the reference material for the written test. The reference text was developed through funding by the RMC Research Foundation. View the text outline of the Pervious Concrete Contractor Certification.

NRMCA Pervious Concrete Contractor Certifications shall be valid for a period of five [5] years. The expiration date for the certification shall be based on the date of completion of the written examination.

 

Exam Information

 

The two-hour written examination is "closed book," consisting of approximately 50 multiple-choice questions. The passing grade for the written examination is 75%

During the performance evaluation, each examinee must demonstrate procedures for placing, compacting, finishing, edging, jointing and beginning curing a pervious concrete slab. The examiner will observe and evaluate the techniques used and record passing or failing grades on the various individual procedures. A passing grade is defined as "no significant variation from proper procedure and no more than two variations from proper technique in the use of the tools."

 

The project experience or work experience must include placing, consolidation, finishing, edging, jointing and curing of pervious concrete and must be documented on the Installer Application form or the Craftsman Application.

 

Recertification 

 

Recertification is required every five years and requires successful completion of a written examination.
