Negative pitch creates an undesirable situation for you, the homeowner. Whenever it rains or when snow melts, the water flows toward your house and seeps into your foundation. Water always flows downhill, so the simple and effective solution is to change the direction of the flow away from your house.
Adjusting the grade so the negative pitch toward your home becomes a positive pitch, with water flowing away from your home, is often the best and most cost-effective solution. Combine grade adjustments with a drainage tile system and you will have functional drainage solutions for years and years.
