4.5m x 100m Non-Woven Geotextile Filter Membrane / Drainage Fabric 80g (450m2/Roll)

4.5m x 100m geotextile filter membrane, manufactured from 80g/m² non-woven polypropylene fibres, covering 450m² per roll. Designed for drainage and soil separation, it allows water to flow freely while preventing fine soil particles from washing into drainage layers. The fabric is commonly used in soakaways, French drains, and behind retaining walls, where it preserves the efficiency of the drainage system by stopping soil fines from clogging gravel or perforated pipes. Its non-woven structure balances permeability with particle retention, ensuring long-term stability in domestic and light civil applications. Durable, rot-proof, and chemically inert, this roll size provides efficient coverage for large-scale drainage systems, commercial landscaping, and civil engineering projects.
