Floor Tile Inspection & Installation Requirements

Q: Are flexural strength and modulus of rupture qualities important in a stone paving project?

A: They could be important if the piece size is large, if a thin set installation method is used, or if the substrate has minimal deflection acceptability. These tests measure the ability of the stone to withstand and resist bending forces. In large piece sizes, it is difficult to achieve full bonding of the stone. In a thin set method, there is a problem of unsupported edges of the stone, as water-based thin set materials shrink when curing. Deflection of the substrate will also cause the stone to have to resist weight of traffic.
