My wife is disabled with Cerebral Palsy and therefore can’t walk on ice or snow, so we must be able to use lots of de-icing salt on our front path. We would like to replace the paving with something that looks nicer. What are our options?
Perhaps pre-sealed pavers/bricks (but I really like the rubber paver option above).
Having never lived in a place where icing of pavements is more than a 10-minute problem, I'd never really thought much of this issue before. If I understand correctly, the problem is where the concrete absorbs saline water via capillary action which then causes the concrete paver to fret, distort or crack due to expansion/contraction of water inside plus the increase in pH (which in turn draws in more water).
Some brief research tells me that a plethora of products exist to seal pavers which contain or silicon a similar substance, filling air gaps and repelling water. I presume it must be possible to buy pavers that have been pre-treated with such a product if you're willing to pay extra for it. A quick google search confirmed dozens of such options exist in Australia at least so there must be loads of competition in the US. And, evidently, the resilience of such concrete pavers is further enhanced by applying extra sealant after the paving is laid.
