Black Nonwoven Geotextile 250g

Black Nonwoven Geotextile 250g

What It Is

A needle punched nonwoven geotextile in black, made from PP or PET staple fibre on the transverse web line and the needle loom. This grade is 250 g/m2, supplied in roll widths of 1 m to 6 m and roll lengths of 50 m, 100 m, 150 m and 200 m; white and grey are also produced.

What It Does

• Cushion: the thick punched face protects the HDPE liner below it from puncture by stone and root.
• Separation: keeps the soil and the drainage or protection layer apart, so the aggregate does not sink into the subgrade.
• Filtration: water passes through the cloth while soil fines are retained, which keeps drains from clogging.
• Reinforcement: distributes load and limits lateral movement of the fill; strength and elongation hold even when the cloth is wet.

The fibre resists acid, alkali, corrosion and ageing in soils and water of different pH and is not damaged by micro-organisms or insects. The cloth stays dimensionally stable, and being light and soft it rolls out quickly on site.

Where It Is Used

Under pond and reservoir liners, in landfill base and cover systems, behind retaining wall backfill, in drainage blankets and slope protection, under riprap and concrete blocks, and in road and railway subgrade separation.

Product Photos

The black cloth unrolled over a lined basin, with the overlap running along the slope so the liner stays covered during backfilling.

Edge detail at a pond: the nonwoven is turned down and held with stone before the riprap goes on. Rolls, sample stacks and the winding face are shown in the product images at the top of this page.
