Dallas Home Inspections, Grading & Drainage
Maintaining Your Home Series
Defects in soil grade and water drainage around homes is a common problem that should be corrected to improve the longevity of your home's foundation performance. Things like high soils, low soils, erosion and improper drainage are normally easy to repair. These are sometimes a problem from the time a home is built and sometimes they happen over time.
High soil levels can contribute to water intrusion and wood destroying insects. High soil levels allow moisture to enter through weep holes, conceal observable defects in the foundation perimeter beam and hide the entry points of wood destroying insects. Proper soil level (including mulch) at the foundation should allow 4-6 inches of the foundation to be visible in all areas.
Improper grade slope may also allow unwanted water to damage a home's foundation over time or even enter the walls. Proper grade slope is when the soil is graded downward and away from the foundation at a slope of about 6 inches per 10 feet. Water should never flow towards the foundation.
Negative grade slope is when the slope is downward towards the house. Negative grade is a problem that should be corrected to prevent possible flooding, water intrusion into the home, water ponding, soil erosion and other problems.
