Needle Punched Non Woven Geotextile

Needle Punched Non Woven Geotextile

What It Is

A needle punched nonwoven geotextile made from polypropylene staple fibre laid transversely and punched on the needle loom. It is supplied in 100-1000 g/m2, roll width 1 m to 6 m and roll lengths of 50 m, 100 m, 150 m and 200 m, in white, black, green or brown as required.

What It Does

• Filtration: gaps between the fibres keep the cloth porous, so water and gas pass while clay particles are held back.
• Separation: keeps soil and gravel layers apart under railway subgrade, airport surfaces and parking areas.
• Reinforcement: distributes the stress in the soil, prevents lateral movement and improves stability; the plastic fibre keeps enough strength and elongation even when wet.
• Protection: reduces scour of river banks and bed and prevents soil loss.

The cloth resists acid, alkali, corrosion and ageing in soils and water of different pH, is not damaged by micro-organisms or insects, and stays dimensionally stable. Being light and soft, it is easy to transport, lay and install.

Where It Is Used

Filter layers on embankments, channels, seawalls, concrete slopes and retaining walls; separation under railways, roads, airport runs and car parks; reinforcement of earth and rockfill dams, breakwaters and slope fills; drainage behind retaining structures; and bank and river bed protection.
