How important is it to seal newly poured concrete and also exsiting concrete?

My driveway was poured two years ago and sealed (skimpy). I had to replace part of it that pushed up during the freeZing weather. When they poured it, they did not seal it. They promised to return and seal the new batch, however, I have not been able to get them to come back. They promise to return but that has not happened!

Any advice on the importance of sealing or re-sealing concrete driveway? I would appreciate any information that you can give me.

Sealing concrete serves 2 purposes:

1) You should seal the concrete immediately when it is finished. This keeps the moisture in the concrete and will help with proper curing. Rapid drying is one of the main causes of weakened and cracking concrete. Other methods of wet curing can be used instead of using sealer such as covering with burlap and using a soaker hose or sprinkler to keep it wet or by covering the fresh concrete with a sheet of polyethylene and taping all the seams. The concrete should be kept wet or covered for at least 300 degree-days. A degree day is the average temperature over a period of days x the number of days. For example if the average temperature is 60 degrees over a five day period:

60 degrees x 5 days = 300 degree-days.

2) It helps keep oil stains from penetrating the concrete making it easier to keep clean. The sealer will also help prevent water from penetrating the concrete where it can freeze during cold weather and could cause spalling.

Another thing you should know about the concrete mix used in your driveway: Insist that the concrete is ordered as "air entrained". The concrete plant will add an air entraining chemical to the mix. Air entrained concrete will hold up better against potential problems during cold weather freeze thaw cycles. Use this mix even if you are pouring in the summer to protect your concrete through the coming cold weather months.

Hope this helps.
