Grading and Drainage Issues
Drainage problems are common in landscapes, especially during rainy seasons. Improperly graded landscapes, clogged gutters and downspouts, certain soil types and improper drainage systems can all lead to water accumulation and the subsequent formation of puddles, mud holes, erosion, and flooded basements.
The number one cause of drainage problems is improper grading. This simply means that the land is not sloped correctly so that water can run off of it effectively. When rain falls on a slope that is too gradual, the water will pool and eventually seep into the ground, causing saturation problems. If the slope is too steep, however, the water will run off too quickly, causing soil erosion and possible flooding downstream. If the water slope towards the home, it will pool near the foundation and cause flooding or leaks.
How We Improve Grading
In order to correct drainage problems, you may need to grade your landscape. Grading is the process of sloping the land so that water drains away from the foundation and does not pool. The minimum grade for a drainage slope is about 3 inches per 100 feet
