Nonwoven Geotextiles

GEONIC 100 nonwoven geotextiles are polypropylene needle punched fabrics with high permeability that allow water to flow relatively freely. When used in association with soil, it has the ability to separate, filter, reinforce, protect or drain. These products have a wide range of applications and are currently used to advantage in many civil engineering 
applications including roads, embankments, retaining structures, reservoirs, canals, dams, bank protection and coastal engineering. 

Main basic functions: 

Soil Separation - It is used to prevent road base materials from penetrating into soft underlying soft subgrade soils, thus maintaining design thickness and roadway integrity. Separators also help to prevent fine-grained subgrade soils from being pumped into permeable granular road bases. 

Soil Filtration - It can be used to produce an effective filtration system. The job of a filter is to allow water to pass through the plane of the filter, whilst retaining particles of the filtered soil. 

Soil Drainage - Drainage required in nearly all geotechnical structures. Whether used to remove surface water from a sports field, or to reduce lateral pressure on a retaining wall, the need for effective drainage cannot be underestimated. Drains can be distinguished from filters as such; water travels across the plane of filters and 
travels with the plane of drains.. 

Protection/Barrier - In some geotechnical applications it is necessary to separate or protect one section of the works from another. This could be for a multitude of reasons, including stopping leachate seepage, protecting a structure from moisture and protecting a geotechnical structure from erosion. 

Soil Reinforcement – Geonic 100 can be used to reinforce a soil mass in the hope of increasing the effective angle of shear and reducing the instability of an earth structure. In the reinforcement function, the geosynthetic is subjected to a sustained tensile force or load.
