To effectively fix drainage problems in your yard, you should implement a combination of surface and subsurface solutions to redirect water away from your foundation.

### 1. Improve Surface Grading Establish a positive slope of at least 5% (roughly ½ inch of fall per foot) extending 6 to 10 feet away from your home. Use clean fill soil to raise low areas and compact it thoroughly to prevent future settling.

### 2. Install Subsurface Drainage

• French Drains: Dig a trench 18–24 inches deep with a slope of 1 inch per 8 feet. Line it with geotextile fabric, add gravel, and lay a perforated pipe (holes facing down) to capture groundwater.

• Perimeter Drains: Install these at the foundation footing level to relieve hydrostatic pressure. These systems channel subsurface water to a sump pump or a daylight outlet at least 10 feet away.

### 3. Manage Roof Runoff

• Downspout Extensions: Attach flexible or rigid PVC extensions to direct water 5–10 feet away from the foundation.

• Splash Blocks: Place these at the end of downspouts to prevent soil erosion and pooling.

### 4. Address Sunken Concrete Use polyurethane foam lifting to level sunken patios or walkways. This restores the proper grade and eliminates depressions that trap water against the foundation.

### 5. Utilize Natural Solutions Install dry wells or rain gardens using native plants with deep roots. These features intercept concentrated runoff from roofs and driveways, allowing it to infiltrate the soil safely away from the house.
