Signs Your Yard or Foundation Needs Regrading

Water is one of the most destructive forces a property faces, and most water damage starts with the grade of the land around your home. If you notice any of these signs, your yard may need regrading.

  • Water pools near your foundation or in low spots after rain
  • The ground slopes toward your home instead of away from it
  • Your basement or crawl space is damp or smells musty
  • Soil has eroded near downspouts, along slopes, or at the base of walls
  • Puddles linger in the yard for days after a storm
  • Your driveway, patio, or walkway is cracking or settling unevenly

How Proper Drainage Grading Prevents Water Damage

Good grading shapes the ground so water moves away from your home and off your property. The standard rule is a slope of about one inch of drop per foot for the first six to ten feet away from the foundation. This is called a positive grade, and it is the first line of defense against water damage.

When the grade is right, rain and irrigation water flow away from the structure instead of pooling against it. When the grade is wrong, flat or sloping toward the house, water saturates the soil around the foundation, builds hydrostatic pressure, and eventually finds its way through cracks and joints.

As a grading and drainage contractor, Dirt Wurx SD looks at the whole property: the slope, the soil type, where the water is coming from, and where it needs to go. Grading alone handles surface water, but when the soil is dense clay or the water table is high, we may also install French drains or surface drains to give water a controlled path off the property.

Our Process

1

Site Assessment

We walk the property, check the slope around the foundation, identify low spots and water paths, and discuss what you see during storms.

2

Slope Correction

We regrade the soil to create a positive slope away from the home, filling low spots and reshaping problem areas.

3

French Drains & Drainage

Where grading is not enough, we install French drains, surface drains, or drainage rock to collect and redirect water.

4

Backfill & Finish

We compact the new soil in lifts so the grade holds, then leave the area smooth and ready for landscaping or hardscape.

Grading & Drainage FAQ

How do I grade my yard for better drainage?

Proper yard grading directs water away from your home's foundation instead of pooling near it. The general rule is a slope of about 2% grade, roughly a 6-inch drop over the first 10 feet away from the house. For yards with drainage problems, this often means regrading the soil, adding French drains, or combining grading with a drainage system depending on how much water needs to move.

How much slope should there be around my house foundation?

Most building codes call for at least a 6-inch drop in elevation within the first 10 feet away from the foundation, roughly a 5-6% grade. Less than that, and water tends to pool against the foundation instead of draining away, which over time can lead to cracking, moisture intrusion, and settling.

What's the difference between rough grading and finish grading?

Rough grading is the first pass, leveling and shaping the land to the general elevations needed for construction, drainage, or landscaping. Finish grading is the final, precise pass that smooths the surface, sets exact slopes for drainage, and prepares the site for sod, seeding, or paving. Most projects need both, in that order.

What is residential excavation?

Residential excavation is the process of digging, moving, or removing earth for home projects like foundation prep, utility trenching, pool installation, drainage systems, or site clearing. It's typically done with heavy equipment like excavators and skid steers, and it's the groundwork step that has to happen before most major home construction or landscaping projects can begin.

What type of soil should be used for grading around a foundation?

Compactable soil with low clay content works best around foundations. It drains well and doesn't expand and contract with moisture the way high-clay soil does. A sandy loam or engineered fill is common. Avoid pure topsoil directly against the foundation, since it holds moisture and can contribute to drainage problems instead of solving them.
