Porous Pavers in the Kitchen (Xeripave)

We did a indoor test of the Xeripave porous paving product.  I was very impressed by how it worked under the kitchen sink.  The question is how does the product withstand shoveling, snow blowing, salt residue, and hold up over time.

Q. How durable is Xeripave®?
A. Pavers comply with ASTM freeze / thaw requirements, they are unaffected by salt, they are unaffected by UV and are considered inert.

If you have long-term experience with the paver please let me know about it.
