Best way to repair cracks in a concrete driveway

Q.    My concrete driveway and parking area have become pitted and cracked over the years and I notice that when it rains, the water goes into these cracks and sometimes finds its way into the basement.

Can this whole area be coated with asphalt driveway sealer or would you recommend putting an asphalt topping over the concrete? A thick covering would cause the garage openings to be lower and allow water to enter the garages. Your advice would be greatly appreciated.

A.    You should check the condition of the grade and any appurtenances around your house to see if they are responsible for the basement wetness and, if they are, you should get them fixed. Although it’s possible, it is less likely that the cracks in the driveway are the cause of the wetness unless the driveway pitches toward the garages. An asphalt driveway sealer is not the answer; the cracks have to be filled with something more substantial.

Considering that it sounds as if your driveway is very flat, your best option, if the damage is not too extensive, is to have the pitted areas and the cracks repaired with a product like Thorocrete or Top’N Bond. However, if the entire surfaces of the driveway and parking area are affected, an asphalt topping may be the best bet if it can be thin enough not to lead water into the garage.
