The installation of pervious concrete requires the placement of ready-mix into forms. Unlike permeable pavers, pervious concrete also requires extensive curing time. Pervious concrete has the most particular installation requirements of the various permeable pavement types. It is recommended that contractors with certifications for the installation of pervious concrete, such as National Ready Mix Concrete Association certifications ([https://www.nrmca.org/certifications/ NRMCA, 2022])<ref> National Ready Mix Concrete Association. 2022. Certifications https://www.nrmca.org/certifications/</ref> are tasked with its installation. See [[Permeable pavements: Specifications]] for more information.
