How does water enter a French drain?
Herein, should there be standing water in a French drain?
If groundwater collects in the basement, it is not only an inconvenient eyesore for the homeowner, it can also lead to wood rot and mold. The most reliable way to eliminate undesirable, free-standing water is to install French drains with slotted pipes, filter fabric and gravel.
Beside above, will a French drain be enough? 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.
Similarly one may ask, do French drains work?
Most descriptions of a french drain involve a slotted or perforated pipe, a trench, geotextile fabric and gravel backfill. Properly constructed, french drains will work well to transmit water from the pipe to the exit of the pipe; however, they are not very efficient in dewatering poorly drained soils.
