FAQ
What type of fabric is best for a French drain?
Non woven geotextile fabric is typically preferred because it allows water to pass through while helping prevent soil from entering the gravel and pipe system.
Should I use woven or non woven fabric for a French drain?
For most French drain applications, non woven fabric is preferred because it offers better water permeability and filtration. Woven fabric is generally used more for stabilization applications.
Does this French drain fabric help in clay soil?
Yes. In clay soil, our filter fabric helps separate fine soil particles from gravel while allowing water to enter the drainage system.
Do I wrap the pipe or line the trench?
Many installations line the trench first, place gravel and pipe, then wrap or cover the gravel envelope depending on design preference and site conditions.
Is the landscaping fabric water permeable?
Yes. This highly porous landscape fabric offers a high flow rate of 140 GPM/ft², allowing water to move through while helping retain surrounding soil particles.
How long does geotextile fabric last underground?
When buried and protected from UV exposure, this fabric can last 50+ years.
How does this compare to Mirafi 140N, Propex Geotex 401, or Hanes Geo TerraTex N04.5?
This product is commonly cross-shopped against those styles of 4 oz non woven drainage fabrics. Always compare project specifications, flow rate, strength requirements, and local engineer requirements before purchase.
Can homeowners use this or is it only for contractors?
Both. Homeowners use it for yard drainage projects, while contractors use it for residential and commercial drainage systems.
