These would fall under the more general category of geosynthetics. Geotextile selection can be expressed as a relationship between these 4 basic functions and the properties required by the design engineer. Geotextile Comparison Geotextile Product Comparison. Nilex Nonwoven Civil Geotextile Product. Geotextile sheet.
Nonwoven Geotextiles have a wide range of applications in civil environmental engineering and construction projects. In general geotextiles are typically classified as either a woven a non woven material.

Produced from high quality sheet polypropylene fibres Nilex' s Nonwoven Geotextiles are needle punched to form a strong fabric that retains its dimensional stability is resistant to damage from construction stresses. Scope This work consists of furnishing all material equipment, labor necessary for the installation of geotextiles.
Geotextiles are used as matting to stabilize flow in stream channels and swales. Project Spotlight Learn how GEOTEX 1201 nonwoven geotextile was used to create artificial reefs to reduce the impact of hurricanes - Click here to read the full case study. Quality Fibers ( threads and yarns) used in the manufacture of geotextile shall sheet consist of synthetic. The geotextile drainage sheet is an air gap film with non woven geotextile on one side that provides drainage and filtration. Specifically developed to respond to the installation challenges of geotextile the DuPont™ Typar® products are an important breakthrough compared to other traditional construction techniques. Construction Specification 495 – Geotextile 1. Geotextile placement for subsurface drainage ( Holtz et al. The geotextile drainage sheet is made by heat bonding high density polyethylene to sheet polyester or polypropylene non woven geotextile. Geotextile sand- filled units provide a " soft" armoring solution for upland property protection.
Nilex Woven Geotextiles High Strength Woven Geotextiles are often used for separation stabilization in the construction of roads. Application Guide and Specifications for Geotextiles in Roadway Applications 5. For more information about GEOTEX ® download the sell sheet here. The woven geotextile’ s separation action prevents the mixing of dissimilar soils allowing each soil layer in the road structure to function as intended. Geotextile- related materials sheet such as fabrics formed into mats , webs, nets, grids formed plastic sheets are not the same as geotextiles. From woven stabilization to specially designed fabrics, to non- ‐ woven separation Propex leads the industry in providing geotextile solutions. Geotextiles can improve soil strength at a lower cost than conventional soil nailing. Choosing the right geotextile for your application is often dependant on several different factors including soil types soil texture, application sheet the amount of water/ rainfall in your area. US Fabrics offers a full line of geotextile products. Products > Geotextiles.
Geotextiles for the purpose of soil filtration, roadway stabilization and other civil engineering projects. Nonwoven Fabrics ( Needle Punched) These fabrics are designed to filter soil particles from drainage systems and stabilize roadways to increase performance life. Mirafi® H2Ri woven geotextile is a revolutionary continuous moisture management system for base course reinforcement and subgrade stabilization of Transportation, Site Development, and Energy Infrastructure projects such as roads, railways, and airports. Our geotextile sheet including woven geotextile and non woven geotextile is the ideal materials for civil construction applications such as roads, harbors, reservoirs, canals, dams and many others retaining construction to improve soil stability, provide erosion control or aid in drainage. The pressure of backfilled soils holds the Sheet Drain in place.
A filtration geotextile covers the drainage core. The geotextile allows unrestricted flow of moisture into the core while it restricts the passing of soil particles which could contaminate and clog the core.
