French Drain Gravel in Baton Rouge

French drain gravel solutions for Baton Rouge's climate
Baton Rouge's warm, humid climate means heavy rainfall and slow-draining soil common to south Louisiana. A French drain system using #57 crushed stone keeps water from pooling around foundations, in yards, and under walkways. The stone allows water to move freely through the trench while blocking fine sediment that would clog the system. This material is sold by the ton, and bulk orders of 15 tons or more qualify for free delivery to Baton Rouge.
Choosing the material and size
is the standard choice for French drains throughout Louisiana and the Gulf Coast. It consists of angular granite fragments roughly three-quarter inch in diameter. The angular edges lock together and prevent the stone from settling or shifting, while the size leaves room for water to flow through. By contrast, pea gravel is smooth and round, which causes it to compact and shift over time. Mulch and compost, which homeowners sometimes confuse with drain rock, are measured in cubic yards rather than tons and are not suitable for subsurface drainage applications. Use crushed stone exclusively for French drains.
Depth, base and how much to order
French drains typically use between 4 and 12 inches of #57 crushed stone, depending on the drain design and soil conditions. To estimate quantity, multiply the length of the trench by its width and divide by 324 to convert cubic feet to cubic yards. For example, a trench 50 feet long and 2 feet wide with 8 inches of stone needs about 0.25 tons. Use the calculator to estimate your project and get an exact quote by ZIP code. Order #57 crushed stone directly and arrange delivery in Baton Rouge to match your excavation schedule.
Local conditions that affect the build
The wet season in Baton Rouge runs from July through September, when rainfall is heaviest. Tropical storms and hurricanes can dump several inches in hours. Install your French drain before the rainy season arrives to avoid washouts and water damage. The clay-based soils found here hold water tenaciously, so adequate gravel depth is essential for drainage performance. Check local building codes and permits before excavating, especially near property lines or utility lines. The Department of Public Works can advise on stormwater regulations.
Delivery and getting started with French drain gravel
Small orders of 3 to 8 tons arrive within one to two business days. Orders of 8 tons or more ship same-day or next-day, and orders of 15 tons or more ship free. Schedule your delivery to align with your trench excavation so the stone is ready to install as soon as the ground is prepared. Have landscape fabric and perforated pipe on hand before the stone arrives. Clear your driveway or property entrance so the truck has easy access to your project area.
About French Drain Gravel projects
A French drain redirects subsurface water away from foundations, yards, and landscaping. Built with perforated pipe, gravel, and landscape fabric, it filters water while preventing sediment infiltration. In Louisiana's wet climate, French drains are essential for preventing foundation damage and basement flooding.

How a french drain gravel project goes
- Plan and measure the drain routeMark where water tends to pool or seep. Measure the length and width of the area needing drainage, and estimate the depth based on the foundation or lowest point. Use a slope of at least one-quarter inch per foot to encourage water flow downhill.
- Dig a trench and prepare the baseExcavate a trench at the planned slope and width. Smooth the bottom and remove rocks and roots. Lay down landscape fabric to prevent soil from clogging the drainage system.
- Add a gravel layer and install the pipePour #57 crushed stone into the base of the trench. Place the perforated pipe on top of the gravel layer, ensuring the drainage side faces downward for proper flow.
- Cover the pipe and add top gravelWrap the pipe with landscape fabric to keep soil out. Cover the pipe with more #57 crushed stone to the required depth, creating a solid base for the surface layer.
- Finish and test the systemAdd soil and sod on top of the trench. After heavy rain, inspect the drain to confirm water is flowing away from the target area and not pooling at the surface.

French drain gravel in Baton Rouge's climate
Picking the right material for a french drain gravel project in Baton Rouge comes down to how the climate treats it. Subtropical with high water table in many parishes. Drainage and erosion control drive material choice. For french drain gravel work specifically, that means choosing material that handles local moisture and traffic loads without re-dressing every season.
The small market profile of Baton Rouge 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.

How deep should a French drain be?
Depth depends on the water source and where you want it to flow. Foundation drains are typically 4 to 6 inches below grade. Yard drains may go 12 inches or deeper to capture subsurface water. Slope the bottom of the trench at least one-quarter inch per foot to move water toward the outlet or daylight point.
Can I use sand instead of crushed stone?
Sand is too fine and clogs quickly with soil particles and sediment. #57 crushed stone lets water flow freely while landscape fabric prevents silt from entering the perforated pipe. Sand would fill your drain within one or two seasons of heavy rain.
What is the difference between #57 stone and pea gravel?
Pea gravel is smooth and round, which means it settles and compacts over time. #57 crushed stone also leaves gaps where water can move too quickly, bypassing the drainage pipe.
How long does a French drain last?
Well-installed French drains last 15 to 20 years or longer. Landscape fabric slows clogging, and regular inspection of the outlet allows you to catch and fix problems early. In Baton Rouge's wet climate, inspect your drain after heavy rain and clear any sediment buildup.
Do I need a permit to install a French drain?
Most jurisdictions require a permit for drains that extend toward property lines or alter site drainage. Contact the Baton Rouge Planning and Development Department or your local municipality to confirm requirements before digging. A permit ensures your drain complies with safety and utility codes.
What happens if the drain outlet is clogged?
Water backs up into the trench and then into the surrounding soil, defeating the purpose of the drain. Inspect the outlet after heavy rain and clear away leaves, soil, and debris. If the outlet is underground or inaccessible, install a pop-up drain head or a surface grate to keep it clear.
Can I put a French drain in an existing yard?
Yes, but you will need to excavate the trench carefully to avoid damaging utility lines, sprinkler systems, and tree roots. Call 811 before digging to mark the location of underground utilities. Plan your drain route to minimize disruption and stay away from trees or shrubs.
Do I need to replace the stone over time?
Stone does not decompose, but it can become clogged with silt and sediment. Landscape fabric prevents most clogging. If the drain slows, it may be the outlet that is blocked rather than the stone itself. Clean out the outlet first, then inspect the stone layer if water still does not flow.
