Geotextile Fabric for French Drain: Selection and Applications
Geotextile fabric for french drain systems is widely specified for residential drainage, retaining walls, landscaping, and civil engineering projects. For contractors and distributors sourcing drainage materials, selecting the correct geotextile helps prevent soil migration, protect drainage aggregate, and maintain long-term water flow. Available in different weights, roll sizes, and filtration properties, nonwoven geotextiles can be matched to specific soil and project conditions. Why Use Geotextile Fabric for French Drain Systems? A French drain typically consists of a perforated drainage pipe surrounded by clean gravel or crushed stone. Although the aggregate creates a highly permeable drainage zone, surrounding soil can gradually migrate into its voids. Over time, accumulated fine particles may reduce drainage efficiency. A geotextile creates a filtration and separation interface between the natural soil and drainage aggregate. Water can pass through the fab...
