|PSI stands for “Pounds Per Square Inch” and normally refers to the amount of weight a material can support/withstand. Higher PSI’s can be achieved by using pressure to create manufactured materials that are very dense. This density provides strength but can also increase the rate of blade glazing.|
PSI is a common term in the work of masonry and Hardscapes. Different material types such as paver brands, brick brands, and block brands all have different PSI’s and are usually chosen for a certain application. The higher the PSI, the tougher the material, thus making it harder to cut such as a hard porcelain vs a soft marble. Check with you material’s manufacturer documentation for the PSI rating.
