Oklahoma City's Grading Experts
Proper grading and leveling is the foundation of every successful construction project, drainage fix, or property improvement in Oklahoma. 405 Dirt Services delivers precision grading for homeowners, builders, and developers across the OKC metro, whether you need a level building site, a re-graded yard for drainage, or a perfectly prepared pad for a slab foundation.
Grading is the process of reshaping the surface of land to achieve a specific slope, elevation, or level plane. Leveling is a subset, bringing land to a flat, even surface. In Oklahoma, grading is required any time you want to build, pave, or drain properly.
Without proper grading, you risk foundation movement, basement flooding, standing water, and failed concrete work. Getting it right from the start saves thousands in future repairs.
We review existing elevations and drainage patterns. For new construction, we work from your builder's grade plan. For drainage fixes, we assess where water is collecting and design the correct slope to solve it permanently.
Using a box blade or motor grader, we establish the general contour — cutting high spots and filling low areas with balanced cut-and-fill where possible to minimize material cost.
Any filled areas are compacted in lifts to prevent settling. This step is critical under concrete slabs and building pads — skipping it leads to cracked concrete and foundation problems.
We bring the surface to within specification — typically ±0.1 ft for building pads, coarser for yard drainage. The final surface is ready for concrete, rock, or landscaping.
Oklahoma's expansive clay soils make grading both more critical and more challenging than in much of the country. Clay heaves and shifts with moisture — improperly graded lots lead to foundation movement, drainage disasters, and concrete cracking over time.
405 Dirt Services understands Oklahoma soil behavior. We grade to promote positive drainage away from structures, account for clay expansion, and create surfaces that hold up through Oklahoma's dramatic wet-dry cycles.
Grading costs vary based on area size, amount of material to move, and whether fill needs to be brought in or hauled off. Here are typical ranges for residential projects in the OKC metro:

Residential grading in Oklahoma typically costs $500–$5,000 depending on area size, material volume, and project complexity. 405 Dirt Services provides free on-site estimates so you know exactly what to expect.
Signs you need regrading include: water pooling near your foundation, a wet basement or crawl space, erosion channels across your yard, or standing water that doesn't drain within 24 hours after rain.
Yes. If low spots require fill material, we can source and deliver clean fill dirt. The cost of material is separate from labor and is discussed in detail at your free on-site estimate.
Absolutely. We regularly regrade yards around existing homes, driveways, and outbuildings. Our operators are experienced at working tight to foundations and structures without causing damage.
Standard residential grading projects typically take half a day to two days. Larger commercial sites may take longer. We give you a clear timeline at the estimate so you can plan accordingly.
