Exterior Flatwork Finisher Certification

This certification program has been developed to provide the basic knowledge on best practices for placing and finishing concrete flatwork, typically exterior slabs on ground. The goal of certification is to ensure that knowledgeable contractors are selected to install concrete slabs and minimize the potential for failure resulting from installation practices.

This program is not intended for contractor personnel involved in larger projects like construction of large interior floor slabs, streets and local road, mainline paving, or decorative concrete flatwork. Contractors involved in this work may consider programs offered under the ACI Flatwork Finishing Certification or programs offered by other entities.

The program is designed to be administered locally by local sponsoring groups approved by NRMCA who can administer training sessions and facilitate a performance evaluation.

NRMCA provides the content and certification exams to approved local sponsoring groups for administering the certification.
