French Drains & Yard Drainage in Franklin, TN

French Drains · Franklin, TN

Standing water needs somewhere to go

A French drain pulls standing water out of a wet Franklin yard before it reaches the house. Mid South Mulch has been in business since 1996, and French drains have long been part of the work. We handle yard drainage across Williamson County and into Rutherford County. We dig the trench with our own excavators and run 4 inch perforated pipe to an outlet.

Water in a yard is a grade problem before it is a pipe problem. Sometimes the fix is regrading the low spots and cutting a swale, and sometimes it is a French drain. Our yard sits on Lewisburg Pike in Franklin, and we cover Spring Hill, Nolensville, Thompson's Station and College Grove. Quotes are free and on site, so call (615) 599-7550 and we will come look.

What is a French drain, and when is it the right fix?

A French drain is perforated pipe set in a gravel filled trench and wrapped in filter fabric. Water in the soil moves into the gravel and drops into the pipe. Manufacturer install guides face the holes downward so soil stays out of the line. From there the water runs downhill to an outlet and leaves the yard.

It is the right fix when water sits in the soil after the surface has dried. When the ground slopes back toward the house, regrading does more than any pipe can. The Tennessee residential code wants the ground to fall 6 inches in the first 10 feet from the foundation. Where that fall is impossible, the code itself calls for drains or swales.

How we build a French drain in Williamson County clay

The build starts with a locate ticket from Tennessee 811 and a check on the permit rules for your address. Tennessee law calls for at least three and no more than ten working days of notice before digging. In unincorporated Williamson County, a Land Disturbance Permit applies to work that disturbs more than one acre. A yard drain disturbs far less ground than that, and we confirm what your property needs before the first cut.

We open the trench with our own excavator, 5 to 6 inches wide for a small problem. Depth is commonly 8 inches to 2 feet, and the base is cut at a 1 to 2 percent fall. The trench gets a geotextile lining, then 4 inch perforated pipe bedded in washed gravel. We fold the fabric over the stone and close the trench with topsoil from our yard.

Why do Franklin yards hold water after rain?

Franklin yards hold water because the ground takes about 50 inches of rain a year and drains slowly. That normal comes from the nearest National Weather Service station. Across Middle Tennessee, March is the wettest month at 5.76 inches. Two thirds of the year's rain falls in the November through May wet season.

Under the grass, county soils sit shallow over limestone, and clay horizons block water on the way down. The county counts 35 percent clay or more as a blocking layer, so water pools on the surface. UT Extension reports that heavy equipment compacts soil during construction, and the pores left behind drain slowly. UT's test is simple: dig a hole 12 inches deep, fill it with water while the soil is moist, and if it empties in under three hours the drainage is excellent.

What else moves water off a wet yard?

Swales, regrading, dry creek beds and buried downspout lines all move water without a French drain. Surface work costs less than trenching, so we look at the grade before we price pipe. A swale is a shallow channel cut across the yard, and grass swales need a 1 to 5 percent slope. Drainage manufacturers pair surface drains with buried pipe so the French drain carries less water.

Roof water is the load people underestimate. Where expansive soils are known, the residential code sends roof water at least 5 feet from the foundation walls or into an approved drain system. One inch of rain on 100 square feet of roof makes 62 gallons. That is about 1,240 gallons off a 2,000 square foot roof in a single inch. We carry it underground in solid pipe and let it out well away from the house.

How much does a French drain cost?
National cost guides list a shallow exterior French drain at $10 to $50 per linear foot. Another guide puts yard French drains at $10 to $65 per foot. Totals across the country run $2,800 to $6,500, with a $5,000 average. The length of the run and the outlet distance drive the number, so we price yours on site. Our yard grading and drainage cost guide breaks the pieces apart.
How deep does a French drain need to be?
Manufacturer install guides put most water diverting trenches at 8 inches to 2 feet deep. Width is often 5 to 6 inches for a small yard problem. Depth matters less than fall. The base has to drop at least 1 percent, and we cut ours at 1 to 2 percent. Drains at a foundation or a retaining wall go deeper than yard work.
Can I install a French drain myself?
Yes, for a short shallow run into a low spot, a homeowner with a shovel can do it. The work gets harder as the run gets longer. A pro job holds a steady 1 percent fall the whole length and ends at a real outlet. We trench with an excavator and haul the spoil off in our dump trucks. The lawn goes back over the top.
What are the downsides of a French drain?
Soil fines migrate into the fabric and the pipe over time, which slows flow and can clog the line. A drain snake clears a clog. A French drain also needs an outlet, so a flat lot with nowhere to send water is a problem. The trench and the stone also make it cost more than surface drainage. A yard that slopes toward the house needs regrading first.
Do I need a permit for a French drain?
In unincorporated Williamson County, a Land Disturbance Permit applies to work that disturbs more than one acre. It also applies to smaller work that is part of a larger plan of development. A yard drain disturbs far less ground than an acre. Rules differ inside city limits, so we check what your address requires before we dig. That check is part of the free on site quote.
Where does the water go?
To the lowest safe point on your own land: a ditch, a swale, a creek or an emitter. Drainage manufacturers are firm that runoff must never be routed onto adjoining property. Water may not go into a sanitary sewer either. We map the outlet before the trench is dug, because the outlet decides the whole layout. The same rule holds for yard drainage in Brentwood and across Williamson County.
Will a French drain fix water in my basement or crawl space?
Our work stops at the outside of the house. A yard French drain and new downspout lines cut the surface water that reaches the wall. That solves plenty of damp crawl spaces. Water already standing inside a finished basement is a different trade. Interior systems and sump pumps belong to a waterproofing contractor, and we handle the outside.
