3 Inch Flexible French Drain Pipe with Non Woven Fabric, Perforated Drainage Tube for Yard and Garden

Flexible Permeable Drainage Pipe for Soil and Roadbed Drainage Key specifications Material: Nonwoven filter layer, polyester fiber, builtin carbon steel wire Available diameters: 5 cm (2 in) and 8 cm (3.1 in) Length: ; example length 17 m (55.8 ft) Function: Absorb, filter, and drain water Why this product solves common drainage problems Combined filtration and drainage: The outer nonwoven layer filters out sediment and debris while the inner polyester fiber and spiral steel core allow water to pass into the surrounding soil, reducing surface runoff and pooling. Durable and crush resistant: The carbon steel spiral provides strong tensile and pressure strength so the pipe resists crushing and maintains continuous flow under load. Flexible and easy to install: The pipe bends without breaking, allowing fast cutting and laying to fit trenches, curves, and confined spaces. Main features Integrated 3in1 design for water absorption, filtration, and drainage Nonwoven fabric prevents sediment intrusion and prolongs service life Spiral steel wire core delivers good articulation and impact resistance Fast to cut and lay, reducing labor time on site Can be joined directly or connected with a PVC pipe for extra length (PVC not included); designed to allow seepage so small connection gaps are not problematic Suitable for both vertical and horizontal drainage applications Applications and practical scenarios Retaining wall drainage: Install behind retaining structures to relieve hydrostatic pressure and channel water away through vertical or horizontal outlets. Roadbed, highway, and railroad drainage: Use under shoulders and within soft ground layers to improve subgrade drainage and reduce waterrelated settlement. Tunnel and underground drainage: Place around tunnel linings or in underground passages to collect and direct seepage water into designed drainage paths. Installation tips and notes The pipe is designed to let water seep into surrounding soil, so minor gaps at joints do not create a leakage risk. Cut and shape on site as needed; the pipe is flexible enough to follow curves and contours without fracturing. Color and appearance may vary slightly from photos due to lighting or monitor differences. Manual measurement may introduce slight size variations. What makes it stand out Combines filtration and structural strength in a single flexible pipe Simple to extend and adapt on site for custom length requirements Effective in applications where surrounding soil or sand is fine and filtration is required options include custom lengths and choice of diameter to match project requirements.
