CSA A231.1/CSA A231.2, titled "Precast Concrete Paving Slabs/Precast Concrete Pavers," is a standard that provides requirements for the manufacturing and installation of precast concrete paving slabs and concrete pavers. This standard applies to the construction of pavement and roof coverings, as well as pedestrian and vehicular traffic areas.

The scope of CSA A231.1 focuses on concrete paving slabs, which can consist of a single concrete throughout or two layers with a minimum thickness of 4mm. The standard includes units with architectural finishes or tactile surfaces. It also provides information on efflorescence and methods for its removal, as well as installation guidelines for pavement components made with precast concrete paving slabs.

CSA A231.2, on the other hand, covers concrete pavers manufactured from hydraulic cement concrete. Like paving slabs, these pavers can consist of a single concrete throughout or two layers with a minimum face thickness of 4mm. The standard includes information on efflorescence and methods for its removal, installation guidelines for interlocking concrete pavements, and testing and usage of segmental concrete paving units that do not strictly meet the definition of a concrete paver.

Throughout both standards, the terms "shall," "should," and "may" are used to express requirements, recommendations, and options, respectively. Annexes are provided with additional information, such as guidance on efflorescence, installation, and testing, and are designated as normative or informative to define their application.
