Q

synthetic fabric used in landscaping and in landscape or road construction applications as a barrier under mulch or pavement to reduce weed germination and growth, as a filter to reduce infiltration of fine soil into drainage or aeration structures (including tiles or pipes), as a barrier to separate and prevent infiltration of fill or paving layers (e.g., to prevent gravel paving from infiltrating a tree root zone), and/or to spread the load of a paving or fill layer and reduce compaction of an underlying layer. Geotextiles generally allow for the passage of water and for gaseous exchange but will be limited by the material placed above.
