Should I do anything about this? The crack is about 1/16 inch and four or five feet long and first appeared mid-winter. The driveway was poured just over a year before the crack appeared.

I've heard there is a product that is water like and seeps into the crack to prevent water getting in and widening the crack once winter sets in but I haven't gone to the hardware store to look for it.

There are 2 types of concrete: Concrete that that is cracked and concrete that will crack.

There are several products that work well to seal cracks. Oover the years I have found the types that stay flexible to be the best —especially if in a region that has low winter temps below 25F. Below that temperature, I find water will cause more damage if not sealed.

My experience with masonry cracks is that widening them and deepening them is necessary before filling with a repair product. With concrete I always use a bonding agent applied to all surfaces of the crack, and let it dry. A product like Sika Flex can then be used to fill the crack. It is available in a tube, and applied with a caulking gun. If you want a smooth surface you can use a point-up trowel or a taping knife.
