* When tested in August 2012, by Sandberg Consulting Engineers, values reported as:

Mean open porosity 15.23%,

Mean apparent density 2274

Mean Flexural strength 5.00MPa.

 

The frost damage which a stone may suffer when installed in a building will depend on the climatic conditions of the place of use, the relative position in the building and the predicted service life of the building.
