Maintaining landscaping to prevent water accumulation
Proper landscaping plays a vital role in basement waterproofing:
- Ensure plants are at least 2 feet away from the foundation
- Use water-absorbent mulch in garden beds
- Trim trees and shrubs to prevent root intrusion
Creating a French drain system
A French drain is an effective way to redirect water away from your home:
- Dig a trench around the perimeter of your home
- Install a perforated pipe in the trench
- Surround the pipe with gravel
- Cover with soil and slope away from the house
Installing proper gutters and downspouts
Well-maintained gutters and downspouts are essential:
- Clean gutters regularly to prevent clogs
- Ensure downspouts extend at least 5 feet from the foundation
- Consider installing gutter guards to reduce maintenance
Improving soil grading around the house
Proper grading ensures water flows away from your home:
