Line the trench with water-permeable landscape fabric to prevent dirt from entering and clogging the drain. Leave about 10 inches of excess fabric out on each side of the trench and fold back.
Yes the trench should be lined with fabric. A fabric lined trench is better than a sock because larger surface area means it will take longer to clog.
Non-woven geotextile fabric is the best choice for drainage applications where water flow through (permeability) is the main concern. Non-woven landscape fabric is commonly used in French-drains, drain-fields, and erosion control.
The best material for a french drain is a mixture of clean sand and gravel. This is better than gap graded aggregate. This would be the typical aggregate used in making concrete, but of course without the cement. There is one other possible problem.
Pour and compact about 3 inches of gravel or landscaping stone along the bottom of the trench. This will act as bedding for the drainage piping.
Without the gravel and the fabric, however, the drain can clog up with sand and soil over time. We're sorry, there seems to be an issue playing this video.
Dry wells are another effective alternative to French drains, particularly for properties with poor drainage. A dry well is essentially an underground chamber that collects and temporarily stores runoff water, allowing it to seep into the surrounding soil gradually.
French drain depth: About 8 inches to 2 feet deep should be sufficient for many water-diverting projects, though related systems, such as those built around foundations and sub-ground living spaces, as well as the bases of retaining walls, may be deeper.
One step you can take is to install a filter or strainer at the inlet point of your French drain. This can help catch larger debris before it has a chance to enter the drain and cause a clog. Just be sure to clean or replace the filter regularly.

A French drain is a simple trench dug in the ground in the most problematic areas of the yard. The trench is filled with a perforated pipe wrapped in water-permeable fabric, and the pipe is covered with several layers of stone or gravel.
The use of this fabric can be of great benefit to a garden, soil stabilization, or road construction project. There are many benefits of landscape fabric, but its main purposes are to separate soil, stabilize, drain, and filter water or runoff.

Standing water can have many adverse effects on your home's foundation and structural integrity if left unattended.
Installing a French drain costs $500 to $18,000, with a national average of $9,250. On average, you can expect to pay $10 to $100 per linear foot, or between $500 and $5,000 to have a 50-foot French drain installed.
Clay soil has poor permeability, meaning it doesn't allow water to pass through easily. In such cases, the effectiveness of a French drain may be limited as the water may struggle to drain away from the area efficiently. French drains may not be suitable for areas with high water tables.
If installing the drain involves diverting a stream or affecting a wetland, you likely need a permit to move forward. Generally, a small French drain on your property that doesn't change the flow of runoff entering and exiting your yard won't need a permit.
A French drain needs to be surrounded by gravel in order to filter out silt and prevent clogging the drain pipe.
Bluestone is highly favored for French drains because of its larger stone size. This size difference allows for better absorption and drainage, ensuring that water is quickly diverted away from your property. The larger stones allow water to flow through, reducing the risk of clogging.
What landscaping projects does gravel help with drainage the best? Gravel does help with drainage for most landscaping projects. But it all depends on the type of gravel used and the drainage project. For most projects, gravel with a size of 1/2 inch to 1 inch will suffice.
Since the goal of a French drain is to move water away from your home and its foundation, you want to select an exit point that is in a drier area designed to carry runoff water. You should also install the exit point in a location that's closest to your problem area (the spot where water tends to pool).
If you have a problem area where water tends to pool, a trench drain may be the best option. If you want a drainage system that is less visible or installed around the perimeter of yo French drains are long-buried trenches containing a perforated pipe enclosed by gravel.
A French drain has a typical lifespan of 20 to 30 years, although this can vary depending on the quality of the installation and surrounding conditions. Regular maintenance and the materials used, such as PVC or crushed stone, play an important role in prolonging its lifespan.
With stormwater, most likely, your drainage systems would fall under land improvements. Stormwater best management practices such as french drains, downspouts and gutter systems, bioswales, and dry wells could qualify as depreciable assets.
