For example, when downspouts are not used or used incorrectly water can seep underneath a driveway and cause settlement cracks and other related problems.  Another important consideration when it comes to maintaining your driveway in the best condition possible is to avoid chemicals and other types of ingredients such as fertilizer, and deicers indiscriminately on your driveway.  The chemicals can have a negative effect on your driveway and cause it to wear down over time.  Chemical reactions can attack and destroy your driveway so simply avoid using these products.
