Oklahoma City's Drainage Experts
Standing water, erosion, flooded yards, and wet foundations are common problems across OKC metro properties, and they are almost always solvable with the right dirt work. 405 Dirt Services diagnoses and fixes drainage problems for homeowners, developers, and property managers throughout Central Oklahoma. From simple regrading to swales, French drains, culverts, and retention areas, we design and install solutions that work with Oklahoma's soil and rainfall patterns. Veteran-owned. Free estimates.
Drainage solutions are earthwork and infrastructure improvements designed to manage how water moves across and through a property. Poor drainage causes foundation damage, erosion, standing water that breeds mosquitoes, wet basements, driveway washouts, and landscaping loss.
In Oklahoma, heavy spring rains and clay-heavy soils make drainage a critical issue on many properties. If water is collecting where it should not be, the problem will not fix itself. It gets worse every rain cycle until the root cause is corrected.
We walk your property after rain, or review your descriptions and photos, to identify where water enters, where it collects, and where it needs to go. Understanding the full water path is essential before designing any fix.
We design the most cost-effective fix: regrading, channel creation, culvert sizing, or retention. Sometimes the right answer is a combination of methods. We explain the full plan before any work begins so you know exactly what you are getting.
Grade corrections, swale construction, and earthwork are completed with precision equipment. Every change in grade is intentional and calculated to move water where it belongs, not just push the problem to a neighboring low spot.
Where water must pass under a driveway, path, or structure, we size and install the correct culvert or pipe with proper bedding and end treatment to prevent erosion and maintain long-term flow.
Finished grading directs water to its exit point, whether that is a drainage easement, roadside ditch, retention area, or other approved outlet. We leave your property clean and water-ready.
Oklahoma receives an average of 35 inches of rain per year, and much of it comes in intense spring storms. The OKC metro's clay soils do not absorb water quickly. Runoff is rapid and can overwhelm underprepared properties in minutes, causing damage that compounds with every storm.
405 Dirt Services has solved drainage problems on rural acreage, new subdivisions, commercial properties, and established homes across the metro. We understand how Oklahoma's soil, slope, and seasonal rain patterns interact, and how to engineer drainage that works year after year.
Drainage solution costs vary based on the complexity of the problem and the scope of work required. Here are typical ranges for projects in the OKC metro:

Most yard drainage problems in Oklahoma are solved with regrading to direct water away from structures, combined with swales or culverts to channel water to a proper outlet. The right fix depends on your specific site. 405 Dirt Services provides free on-site assessments to identify the root cause before recommending any solution.
Simple drainage regrading typically runs $800 to $2,500. Complex drainage systems with swales, culverts, and retention areas run $3,000 to $10,000 or more. We provide free on-site estimates so you know exactly what the fix will cost before any work begins.
Yes. We regularly install and replace culverts under driveways to restore drainage flow. This is one of our most common repairs across the OKC metro. We assess the correct pipe size and install it with proper bedding to prevent future failure.
We work carefully to minimize impact on existing landscaping. In most cases, regrading in specific areas allows us to solve drainage problems without removing mature trees or major landscaping features. We walk the property with you before work begins to discuss any areas of concern.
Most standing water in OKC metro yards is caused by low spots that hold water, improper grading that slopes toward the house, clogged or undersized culverts, or clay soil that does not drain quickly. We identify and fix the root cause so the problem does not return.
