Controlling water around your home can save you thousands of dollars in repairs. You should have the surface around your home sloping away to allow the water to properly drain. Allowing the water to flow towards your home could potentially cause the water to settle against the foundation and migrate into the building. Other issues could also arise with the soil erosion which could cause stress on your foundation. In severe cases, the water can cause the building to lose structural integrity. Water made the Grand Canyon and is pretty persistent- Control it before its too late.
