Deterioration from salt

[Robert J. OConnor]

I guess some of you guys missed the part where I indicated I have seen almost exactly the same situation first hand, and it was indeed from melting road salt laden snow with a cracked garage slab. Fixed the cracks and the problem was solved. In another case the slab was pitched towards the house, so for a winter they didn't park the car in the garage, and again the problem "mysteriously" disappeared. Really depends on local conditions and winter temperatures to be sure.

With foundation water penetration about 9 times out of 10 foundation waterproofing or footing drain systems are not needed ... just good roof drainage and grade/slab integrity and pitch away from the house. In fact it's my opinion that footing drains actually draw water towards a foundation, which is more likely to cause leaks.

I would bet the family summer home upstate that if ya fixed the slab cracks and drainage in that garage the problem would "mysteriously" disappear ... that is if I had a family summer home upstate ...
