A French drain is a gravel-filled trench with a perforated pipe at the bottom that intercepts groundwater and surface water before it reaches your home, yard, or structure. Done correctly, it redirects that water away from problem areas and discharges it safely downhill or into a dry well.
In Central North Dakota, drainage problems are common. Clay soils don't absorb water well, spring snowmelt is heavy and fast, and flat terrain means water has nowhere to go without help. Dakota Earthworks installs French drain systems throughout McLean, Burleigh, Morton, Oliver, Mercer, and Ward Counties — sized and sloped correctly for North Dakota's conditions.
Types of Projects We Handle
- Wet yards and lawn drainage — standing water after rain or snowmelt
- Foundation perimeter drains — intercept groundwater before it reaches basement walls
- Driveway and parking area drainage — keep gravel firm after spring thaw
- Retaining wall drainage — prevent hydrostatic pressure buildup behind walls
- Hillside curtain drains — intercept slope drainage before it reaches structures
- Rural and farmstead drainage — shops, outbuildings, equipment yards
- Integration with buried downspout systems and foundation drainage
- Garrison, Coleharbor, Riverdale, Totten Trail, and Three Mile area properties
- Bismarck, Mandan, Minot, Hazen, Beulah, Turtle Lake, and Underwood area properties
Our Installation Process
Site Assessment & Design
We walk the property, identify where water enters, and design the routing with consistent slope from inlet to outlet.
Utility Locate
811 call placed before any digging to confirm underground utility locations along the planned route. Required on every project.
Trench Excavation
Trench excavated to required depth — typically 18 to 36 inches — with slope checked and maintained throughout.
Fabric & Gravel Bed
Filter fabric lined in trench to keep clay fines out. Clean washed aggregate placed as a bedding layer at the bottom.
Pipe & Outlet
Perforated pipe laid on gravel with correct orientation and slope. Solid outlet pipe connected to the discharge point.
Backfill & Grade
Aggregate backfilled over pipe, fabric folded over top, trench restored and graded for seeding or landscaping.
Why French Drains Fail — and How We Avoid It
French drains are simple in concept but easy to install incorrectly. The most common failure modes in North Dakota:
- Insufficient slope. A system without consistent fall holds water instead of draining it. Every trench we excavate is checked for slope throughout the full run.
- No filter fabric. In ND's clay soils, a system without filter fabric will clog within a few years as fines migrate into the gravel. We use fabric on every installation.
- Undersized pipe. During spring snowmelt, drainage volume is significant. We size pipe to the drainage area being served, not a one-size-fits-all approach.
- No defined outlet. Water collected has to go somewhere. We plan the outlet location at the design stage, not as an afterthought.
- Shallow installation. In Central ND, frost can push shallow systems or block them during the critical spring drainage period. We design depth for seasonal conditions.

Frequently Asked Questions
How much does a French drain cost in North Dakota?
Cost depends on system length, depth, access conditions, and discharge point requirements. A short residential yard drain runs considerably less than a long perimeter system around a foundation or shop building. Call us with your situation and we'll give you a straight number.
How long does a French drain last?
A properly installed system with filter fabric and clean aggregate should last 20 to 30 years or more. Systems installed without fabric begin failing sooner as clay fines migrate into the pipe and restrict flow.
Where does the water go when it drains?
Outlet options include daylighting at a lower point on the property, a dry well or infiltration area away from buildings, or connection to an existing storm drainage system. We determine the best outlet during the site assessment.
Can a French drain handle snowmelt in North Dakota?
Yes — but the system needs to be designed for it. ND spring thaw produces high water volume in a short window. We size pipe and slope systems for spring conditions, not just summer rain events.
Do I need a French drain or a buried downspout system?
They solve different problems. A French drain handles groundwater and sheet flow across a yard or along a foundation. A buried downspout system captures roof drainage at the gutter outlet and routes it away from the building. In some cases both are needed. We'll help you identify the right solution.
Do you haul away the excavated material?
Yes. We have our own truck and can remove excavated soil from the site if it's not needed on the property.
