Woven & Non-woven Geotextiles

Non-Woven Geotextiles

Non-woven Geotextiles Fabrics are probably the most commonly known geotextiles. Non-woven polypropylene fabric, which has a felt-like consistency, combines strength and flow ability. Available in varying weights and thicknesses, the fabrics are strong but permeable, allowing for varied uses. Non-woven fabrics commonly are used as a separator between subsoils and rock riprap, and they also are used to separate soils and sized stone in many ground-level and subsurface drainage applications.

Non-woven Geotextile Fabrics have a random, three dimensional pore structure and are highly water permeable, as is necessary in many geotextile applications. A wide range of fabric weights ranging from 3.1oz. to over 16 oz. is offered to meet the various requirements. We offer the lighter weight fabrics in 3′ X 300′ and 3′ X 360′ rolls for use as Pipe Wrap.

Woven Geotextile

Woven geotextiles are made from polypropylene as well, but the manufacturing process, product characteristics and applications differ dramatically from those of nonwovens. Narrow strands of polypropylene tape are woven together during manufacturing, producing a tough fabric, but one with much less permeability than nonwovens.

Commonly known as ground stabilization fabric, these fabrics are effective in separating less desirable subsoils from gravel or paved surfaces. By effectively bridging over poorer-quality soils, they can provide savings in material costs and project life cycles. Perhaps the easiest way to understand the value of soil separation in roadway construction is to be aware that stone and gravel tend to sink into softer soils. A simple adage that road builders have used for years goes something like this: “Five pounds of stone on top of five pounds of mud equals ten pounds of mud.
