Non-Woven Needle-Punched Polypropylene Geotextile 200 g/m²
Specs checked on
What it is
A white non-woven fabric made from polypropylene (PP) fibres with a mass of 200 g/m², also written 200 gsm. Needle-punched means the loose fibres are locked together by barbed needles rather than woven on a loom, which gives a felt-like sheet that water passes through. Fibre type, method, weight and colour are the facts our product file confirms.
Strength and thickness figures come from two European data sheets for 200 g/m² PP fabrics. The Danosa DANOFELT PP 200 sheet gives a tensile strength of 16.0 kN/m in both directions, a CBR puncture of 2.34 kN and a thickness of 1.74 mm at 2 kPa. The Deschacht NW16 sheet shows 16 kN/m, 2,400 N and 1.25 mm, plus an opening size of 85 µm. Those are similar products’ values, not confirmed for this item.
The roll size, 2 m × 100 m (200 m²), comes from Kitovu’s stock records, and Kitovu’s order specified UV-stabilised fabric with a characteristic opening size (O90) of 0.12 mm. The brand and whether the fibre is staple or continuous filament are still open questions for the supplier. A fuller guide to weights and types is on the geotextile fabric page.

How it is used
Our file has no laying instructions for this roll, so the points below come from the Danosa data sheet for its 200 g/m² PP fabric and are not confirmed for this item. Danosa lists four jobs for it: separating soil layers, filtering, drainage and protecting waterproofing membranes.
- Overlap. Adjacent strips overlap by at least 20 cm, according to Danosa.
- Sunlight. The sheet calls the fabric UV resistant only “for a certain period” and asks for rolls to be stored out of direct sun; its durability figure assumes the fabric is covered.
- Service life. Danosa states a minimum of 25 years when the fabric is covered, in soils with pH 4–9 and soil temperature below 25°C.
Drainage set-ups with a filter fabric are described in the French drain guide and on the soak pit page. For the protection role under a pond liner, the HDPE Geomembrane (Dam Liner), Smooth, 0.3 mm is also in stock in Zanzibar.
