Drainage gravel in Detroit, MI: what the project needs
Most drainage gravel jobs in Detroit, MI fall into a few groups: a French drain along a foundation, a footing drain, a dry well for roof runoff, or a low corner of the yard that stays wet after a storm. Each one depends on stone that lets water pass through quickly while the pipe, the soil and the surface above it do their part.
Choosing the material and size
Four stones on this page cover most of these jobs. Drain Rock is the usual choice for the stone that surrounds a perforated pipe, since its open space lets water move freely. #4 Crushed Stone and #57 Crushed Stone are smaller and fill the space above the drain, with #4 suiting a deeper bed and #57 working as a mid-size fill. River Rock is rounded and looks natural in a visible swale, though it moves more than angular stone on a steep grade.
Depth, base and how much to order
Dig the trench deep enough that the pipe sits in stone with a full layer above it, then add extra depth so the bed can settle a little under its own weight and the soil above it. Settling is slow and uneven, so that margin protects the grade you finished with, not just the first week.
To estimate the stone, multiply the trench length in feet by its width in feet, then by its depth in inches, and divide by 324 to get cubic yards of trench space. Our calculator does that math for you and gives a stone estimate to work from. Round up rather than down so the trench does not run short partway through.
Local conditions that affect the build
Detroit is a city of about 630,000 people in the Detroit-Warren-Dearborn area, and many lots here are older, so walk yours after a heavy rain and mark where water pools. Make sure the trench falls toward the exit, and give it a steeper fall if the soil stays soggy for days. A clean stone surround lets the trench drain between storms. Plan the dig for a dry stretch of workable weather in spring or fall, since saturated or frozen ground makes a neat trench hard to cut and hard to backfill.
Delivery and getting started
Stone is sold by the ton and delivered to your ZIP code. The price shown on the page is the delivered price for your ZIP, calculated live, and larger orders get a lower rate per ton. Detroit drainage gravel orders start at 2 tons.

About Drainage Gravel projects
Drainage gravel is open stone that moves water away from a foundation, a low yard or a downspout. In Detroit, MI, homeowners and small contractors use it to fill French drain trenches, surround footing drains and line dry wells. The right stone depends on the trench, the soil and how much water the drain has to carry.

How a drainage gravel project goes
- Pick the exit and check accessPick the exit point first, then trace the route from the trench start to it. Note tree roots and any sprinkler heads along the way. Confirm a delivery truck can reach the drop spot before the dig is scheduled.
- Excavate a clean, even trenchDig to the width you planned and keep the walls straight. Clear loose clumps and rocks from the bottom so the pipe rests on firm ground rather than on pockets of soft soil. Mark the trench edges with stakes or spray paint so everyone knows the line before the stone arrives.
- Lay the pipe on a stone bedSpread a first layer of stone in the bottom, then set the perforated pipe with its holes facing down. Keep the run straight between access points so a cleaning tool can pass through later. Fill around the pipe until it is fully supported, and do not let the stone push it out of line.
- Fill the drain zone in even layersAdd stone in lifts of even thickness and rake each one level before the next. Keep soil clumps out of the stone as you go, since they can block the spaces that carry water. Stop once the stone reaches the level you planned and leave the top free for the cover layer.
- Cover, then test the flowTop the stone with soil or sod, then run a hose into the trench to confirm water reaches the exit. Watch for pooling at the surface or a slow discharge, and fix either one before you finish the lawn or the bed. A short test now saves digging again later.

Drainage gravel in Detroit's climate
In Detroit, the local climate shapes which drainage gravel materials hold up over a full year. Long freezing winters and high snow-melt loads. Aggregate base needs to drain fast or it cracks. For drainage gravel work specifically, that means choosing material that handles local moisture and traffic loads without re-dressing every season.
The small market profile of Detroit also shapes how a project runs. Most jobs are residential, with the occasional school or municipal project. Truck access is usually wide and turnarounds run fast.

Do I need landscape fabric around drainage gravel?
Fabric helps keep soil from working into the stone and clogging the open space, so it is common in French drains where fine soil surrounds the trench. Some builds skip it, especially where the trench sits in clean sand or where the stone is a deep base rather than a drain zone. If you use fabric, lay it along the trench walls and over the top of the stone before backfilling, and overlap the seams so soil cannot slip through at the joints.
How do I connect a downspout to a drain trench?
Run the downspout into solid, unperforated pipe and carry it to the outlet or a dry well, and keep it separate from the perforated line until the two meet. Roof water arrives in a rush, so the solid section moves it past the trench instead of flooding it. Add a cleanout or a removable cap at the joint so leaves and grit can be cleared out without digging.
Do I need to call before I dig?
Yes. In the United States, call 811 before you dig so utility lines can be marked. Marks show buried gas, power, water and phone lines, but they do not show private lines such as a feed to a detached garage. Look for those yourself, and check whether your city requires a permit for work near a sewer connection or the street.
Can one person install a French drain?
A short trench in soft soil is a manageable job for one person with a trencher or a sturdy shovel and a level. Long runs, deep trenches or heavy clay usually call for a rented machine and a second pair of hands. Bulk stone arrives as one large pile, so plan how you will move it by wheelbarrow before the truck comes.
How long does drainage gravel last?
The stone itself does not rot or break down, so the trench lasts as long as it keeps moving water. The usual weak points are the pipe, the fabric and soil that migrates into the stone over time. Check the outlet each spring, look for soft spots on the surface, and flush the pipe if your design has cleanout ports. A drain that slows down is usually telling you to clear the outlet first.
What should I do with the soil from the trench?
Keep topsoil separate from subsoil if you plan to backfill the surface with it. Subsoil that is heavy clay can go back in the trench above the stone as long as the drain zone stays intact, or it can be spread in a low area that needs filling. Soil that is contaminated or full of debris should not go back in the yard, so check with a local hauler before you start digging.
Is drainage gravel a good base for a patio?
Not on its own. Open-graded stone shifts under foot traffic and does not lock, so pavers can settle unevenly. A patio base is usually a compacted layer of denser crushed stone with a bedding layer above it. If you want a drain under a patio, place the drain stone beside or below the base rather than replacing it.
Will heavy rain wash the stone out of the trench?
Stone sized for the flow and covered properly stays in place. Washout usually happens when water runs across the top of the trench rather than into it, or when the cover soil is too loose. Keep an eye on the first storm after the build, and fill any low dip with a few shovels of stone before it grows.
