If your yard holds water after every rain, fall is the time to deal with it. Once the ground freezes, that standing water turns into ice, heaving, and a wet basement problem you will be thinking about all winter. A French drain is one of the most common fixes we see customers tackle this time of year, and it is very doable in a weekend with the right machine if you plan before you dig.
Start With Where the Water Needs to Go
A French drain does not make water disappear. It collects water in a gravel-filled trench with a perforated pipe and carries it to a lower outlet, where it can daylight at a slope, a ditch, or a dry well. Walk your yard after a rain and note where the water sits, where it comes from, and where it can realistically end up. The trench needs a steady downhill slope from start to outlet the whole way. A drain with no place to discharge is just an underground pond, so settle the outlet first and work backward from there.
Before any digging, call 811 to have underground utilities marked. That step is free and a lot cheaper than finding a line with a bucket.
Sizing the Trench
For most residential drainage work, the trench is wider than people expect. You need room for the pipe plus gravel around and over it, so a trench in the range of 12 to 18 inches wide is a practical target for many jobs. Depth depends on what you are draining. A shallow swale area may only need the pipe a foot or so down, while a drain protecting a foundation or crossing a low spot usually runs deeper. Whatever depth you choose, keep the slope consistent. High and low spots in the trench floor become places where water and silt settle, and the drain slowly stops working.
Line the trench with landscape fabric if you are working in soft or silty soil, lay the perforated pipe, cover it with washed stone, fold the fabric over the top, and backfill. The fabric and clean stone are what keep the drain working years from now instead of clogging in the first two seasons.
Which Mini Excavator Fits the Job?
This is where bucket size matters more than raw power. Our Bobcat E35 Mini Excavator comes with a 12-inch or 24-inch bucket, which lines up well with a typical French drain trench. The 12-inch bucket cuts a clean, narrow trench with less gravel to buy and less soil to haul off. The E35 is also a zero tail swing machine, so the back of the excavator stays within the width of the tracks as it rotates. At just under 70 inches wide, it works comfortably along fences, between houses, and in backyards where swinging into a fence or a foundation is a real concern. Its digging depth of about 10 feet is far more than a drainage job needs.
Step up to the Bobcat E48 Mini Excavator when the job gets bigger: a long drain run across a large property, deeper foundation work, heavier soil, or a project that combines drainage with grading, stump removal, or footing work. The E48 is a larger machine at 9,830 pounds and about 73 inches wide, with similar digging depth and more lift capacity. For a straightforward backyard drain, it is usually more machine than you need; for long runs, the extra size pays in speed.
When a Trencher Is the Better Tool
If your project is a single narrow line, such as a buried downspout extension, an irrigation run, or a cable trench, a walk-behind trencher may be faster than an excavator. Our Ditch Witch C24X Trencher cuts up to 6 inches wide and 36 inches deep in one steady pass. That narrow cut is perfect for pipe and cable. It is not the right tool for a true French drain, though, because you need width for the gravel envelope around the pipe.
A Practical Weekend Checklist
- Walk the yard after rain and mark the wet area and the outlet point
- Call 811 and wait for utilities to be marked before digging
- Stake the trench line and check the slope from start to outlet
- Order perforated pipe, washed stone, and landscape fabric ahead of time
- Choose your bucket width before pickup, 12-inch for most drain trenches
- Plan where the excavated soil will go before the first bucket comes out
- Dig, set the pipe, and check the slope again before adding stone
- Cover with stone, wrap the fabric, backfill, and tamp in lifts
Mistakes That Cause Rework
The most common failure we hear about is a flat trench. Even a small belly in the run collects silt and shortens the life of the drain. The second is skipping the fabric and using cheap stone, which lets fine soil migrate in. The third is underestimating the soil you will move. A 100-foot trench produces a surprising pile, so decide up front whether it gets spread on site, used for grading, or hauled away.
Fall ground in Michigan is usually in good shape for this work: soft enough to dig cleanly, dry enough to grade, and not yet frozen. Get the drain in now and the spring melt becomes a non-event instead of an emergency.
