MRMCA is the Approved Local Sponsoring Group for NRMCA Exterior Flatwork Certifications.
This certification program has been developed to provide the basic knowledge on best practices for placing and finishing concrete flatwork, typically exterior slabs on the 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 the construction of large interior floor slabs, streets / roads, mainline paving, or decorative concrete flatwork. Contractors involved in this work may consider programs offered under the ACI Flatwork Finishing Certification
