Geotextile Membrane – Non-Woven – Outdoor Drainage

Product Overview

Enhance your drainage systems with this 1m x 10m non-woven geotextile filter membrane, designed using 80g/m² polypropylene fibers. Covering 10m² per roll, this membrane allows water to flow freely while preventing fine soil particles from infiltrating drainage layers.

Ideal for use in soakaways, French drains, and behind retaining walls, this fabric maintains the efficiency of drainage systems by blocking soil fines from clogging gravel or perforated pipes. Its non-woven structure offers a perfect balance of permeability and particle retention, ensuring long-term stability in domestic and light civil applications.

Durable, rot-proof, and chemically inert, this compact roll size is perfect for narrow drainage trenches, small soakaways, or patch repairs to existing systems.
