Program Summary
With increasing interest in pervious concrete, we recommend
only NRMCA certified contractors. The NRMCA established
a task group which has developed a certification program
for contractors qualified to place pervious concrete.
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 NRMCA Pervious Concrete Contractor Certification
is modeled after ACI ‘s Flatwork Finisher Certification.
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 will only provide certification exams
to approved Local Sponsoring Groups for administering
the certification. At least 20 local groups have expressed
interest in administering the certification program.

Two levels are possible:
1) Pervious Concrete Technician, which
requires passing a written exam. A Pervious Concrete
Technician is a person who is knowledgeable about proper
procedures to place, consolidate, finish, edge, joint,
cure and protect pervious concrete pavements, but who
lacks sufficient work experience to qualify as a concrete
craftsman.
2) Pervious Concrete Craftsman, which
requires passing the same exam plus some level of work
experience and/or passing a performance exam component.
A prerequisite is the ACI Flatwork Finisher certification
which ensures that the craftsman knows the basic level
of care needed for flatwork construction.
Pervious Concrete Craftsman is more knowledgeable because
he/she not only meets the Technician requirements but
also has earned ACI Flatwork Finisher Certification
and, through documented work experience, can demonstrated
the ability to place, consolidate, finish, edge, joint,
cure and protect pervious concrete pavements.
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
