Nonwoven Geotextile Fabric

A Nonwoven Geotextile Fabric is a permeable fabric that separates poor soils, provides high flow, and at certain strengths stabilizes the subgrade. A needle punch nonwoven geotextile is made from polypropylene fiber and has a felt-like texture. Nonwoven geotextiles are also known as filter fabrics and drainage fabrics.

Lightweight nonwoven geotextiles are most commonly used as a drainage and separation layer. Typical applications include pipe wrap on road and utility projects, filter fabric for landscaping projects and drainage fabric for retention and detention systems. These geotextiles range from 3.0 ounces to 4.5 ounces.

Medium weight nonwoven geotextile fabrics are used for drainage, separation and stabilization. These fabrics have a greater tensile strength than the lightweight fabrics but lower permittivity. That means they are stronger than the lightweight geotextiles but not as permeable.

A medium weight nonwoven fabric is a great drainage layer for separating soils. When used for separation, medium weight geotextiles prevent contamination between soil layers while still allowing water to pass through the subgrade. This group of geotextiles is often used in combination with a geogrid to achieve maximum stabilization and separation on unstable subgrades.

Heavyweight nonwoven fabrics act as a soft separating geotextile layer between rough aggregate and other geosynthetic structures. The felt-like fabric provides protection for sensitive structures such as geomembranes and liners that can be compromised if they are punctured, ripped or torn. Heavyweight nonwoven fabrics are also applied for stabilization under roadways.

Environmental nonwoven geotextile fabrics line landfill cells and stormwater ponds.

On landfills, these needle-punch nonwovens separate stone from geosynthetic liners. The environmental nonwoven geotextile provides a cushion layer and separation layer to also prevent contamination between soil/stone and trash.

In stormwater ponds, environmental fabrics separate groundwater from the retention pond while providing a cushion layer under the geosynthetic liner.

Weight is the critical difference between a civil nonwoven and an environmental nonwoven. Weight is reported as a typical value for a civil nonwoven. A typical value represents the mean value. This means 50% of the values can exceed the typical value and 50% of the values can be lower than the typical value.

The weight of an environmental geotextile is reported by the Minimum Average Roll Value, also known as MARV. MARV is derived from the average value less two standard deviations. As a result, geotextile testing according to MARV is more accurate. When comparing civil nonwovens to environmental nonwovens, the MARV weight as tested and reported for environmental nonwovens is more accurate than the typical value weight reported for civil nonwovens.

A needle-punch nonwoven Paving Fabric relieves stress between road layers. This reduces cracking and deterioration, increases the road’s flexibility, and ultimately aims to increase the road’s lifespan.

Paving Fabrics are bonded to the road surface and saturated with bitumen (a petroleum based liquid binding agent found in asphalt). This layer seals the pavement and waterproofs the overlay.
