CMHA makes no representations or warranties of any kind, expressed or implied, and disclaims any liability for damages resulting in the use of this guide construction specification.
There are two methods used for mortared applications of concrete paving slabs. They are (1) setting pavers on a thick workable latex-fortified mortar bed and (2) sometimes applying a bond coat and then a thin layer of latex-fortified mortar. The latter procedure is called term “thin set.” Both methods place mortar on a cured concrete base.
The installation methods referenced in this guide specification are found in ANSI Specifications for Installation of Ceramic Tile and the Tile Council of America’s Handbook for Ceramic Tile Installation. Reading these references is a prerequisite to using this guide specification. Mortar manufacturers can provide additional guidance on selection and installation of their products depending on which installation method is chosen. Grout in this guide specification refers to mortar used to fill paver joints.
