How to Seal a Concrete Patio Crack in Winter

I have a site visitor to HomeAdditionPlus.com asking how to seal a concrete patio crack in winter, and in a cold climate.

The concrete patio has about a 1" wide crack in it and when the snow and ice melt, water seeps through the crack, underneath the patio and into the basement.

My only recommendation is to keep the patio free from snow and ice, and put plastic and sand over the crack until warm, dry weather returns.

If anyone else has a better idea let me know so that I can pass along the tip.
