Mirafi® N-Series

Nonwoven Polypropylene Geotextiles

Mirafi® N-Series nonwoven polypropylene geotextiles are used for soil separation, drainage in Transportation, Building Site, and Water Infrastructure projects such as subsurface drainage, permanent erosion control and roadway separation applications. Mirafi® N-Series nonwovens combine high water flow rates, high soil interaction and durability while providing excellent soil particle retention.

Key Features

TenCate develops and produces materials that function to increase performance, reduce costs and deliver measurable results by working with our customers to provide advanced solutions. The Difference Mirafi ® N-Series Nonwoven Geotextiles Make:

Construction:

Mirafi ® N-Series polypropylene nonwoven geotextiles easily conform to the ground or trench surface for trouble free installation.

Mirafi ® N-Series geotextiles withstand installation stresses with high puncture and tear resistance.

Drainage:

High permittivity properties provide high water flow rates while providing excellent soil retention.

Environmental:

Mirafi ® N-Series geotextiles are chemically stable in a wide range of aggressive environments.

Cost Effective:

Mirafi ® N-Series geotextiles provide economical solutions to many civil engineering applications including a cost effective alternative to graded aggregate filters.

Products

Mirafi® 140NL

Mirafi® 135N, 140NL and 140NC are lighter weight versions of Mirafi® 140N . These products were developed to meet specific agency (DOT’s, MTO’s, etc.) requirements. These products can be used in areas where they meet the local agency requirements. If there are no prevailing agency specifications, it is recommended to follow AASHTO M288 for subsurface drainage applications.

Mirafi® 1160N

Mirafi® 1100N, 1120N and 1160N are heavy weight nonwoven geotextiles for more severe or extremely harsh conditions, such as rip-rap and revetment applications. Contact your local TenCate Geosynthetic representative for the proper use and specification of these products.

Functions

Drainage

The equilibrium soil-to-geotextile system that allows for adequate movement of a liquid across the plane of the geotextile over the service lifetime of the application.

Filtration

The equilibrium soil-to-geotextile system that allows for adequate movement of a liquid across the plane of the geotextile with limited soil loss over the service lifetime of the application.

Separation

The placement of a flexible, porous geotextile between dissimilar materials so that the integrity and intended functions of both materials remain intact or are improved.
