4 Inch Flexible French Drain Pipe with Filter Sleeve, Expandable Perforated Drainage Pipe for Yard 90m

Soft infiltration drainage pipe designed to capture, store, and drain rainwater into surrounding soil while preventing sediment entry. Key benefits Controlled infiltration and storage: Lets rainwater soak into nearby soil for use during dry periods and routes excess water away during heavy rainfall. Effective filtration: Outer nonwoven filter layer with polyester fiber prevents sediment from entering the pipe while maintaining water permeability for allround penetration. Durable and flexible construction: Builtin steel wire supports the pipe under soil or gravel, keeping the line open and stable for long service life underground. Easy to extend and connect: Pipes can be joined directly for additional length or connected using a white PVC pipe (PVC pipe excluded). Designed for permeable flow, so leaks from fittings are not a functional issue. Low maintenance: Filtered entry and robust materials reduce the need for frequent cleaning or replacement. Materials and performance Outer layer: Nonwoven filter plus polyester fiber for filtration and water permeability. Inner support: Steel wire reinforcement for strength under burial and cover. Function: Combines water absorption, permeability, and drainage to manage surface and subsurface water effectively. Installation notes Mark the installation route before burying. Do not allow vehicles over the installed pipe. When extending, ensure secure connections and appropriate bedding with soil or gravel to maintain permeability. Typical applications Perimeter French drain around foundations and patios to prevent pooling and direct runoff into the soil. Lawn and garden drainage to store rainwater in the root zone during wet seasons and provide moisture during dry spells. Landscape, sidewalk, and constructionsite drainage where flexible, buried drain lines are needed beneath gravel or soil. This flexible polyester drain pipe with steel wire reinforcement is suitable for yards, backyards, lawns, gardens, fences, patios, sidewalks, commercial zones, and industrial areas where reliable infiltration and drainage are required.
