2 Introduction Nonwoven Geotextile (TechGeo) - Functions & Applications TechGeo is made from the highest quality PP fibers. It is a Nonwoven Geotextile, needle punched to form a strong fabric that relates its dimensional stability adding years to the life of any roadways, railways, landfill, landscaping, horticulture or civil environmental application. This geotextile is resistant to UV degradation and biological, chemical environments normally found in soils.. Geotextile Overview A geotextiles as defined by ASTM as Any permeable material used with foundation, soil, rock, earth, or any other geotechnical engineering-related material, as an integral part of a man-made project, structure, or system. Geotextile are categorized as, woven and nonwoven fabrics. Functions of Non woven Geotextile (TechGeo) Separation Filtration Drainage Containment Protection Barrier Separation TechGeo acts to separate two layers of soil that have different particle size distributions, This prevents base materials from penetrating into underlying soft subgrade soils, thus maintaining design thickness and integrity of the layer. Tech Geo Filtration This allows water to move through the soil while retaining all upstream soil particles. It is used to prevent soils from migrating into drainage aggregate or pipes while maintaining flow through the system. Drainage TechGeo acts as a drain to carry fluid flow through less permeable soils. It dissipates pore water pressures at the base of embankments. Containment TechGeo are used in making geocontainers and geobags which are used in a wide range of applications.

3 Protection TechGeo is used to cushion Geomembrane liners to prevent liner puncture due to drainage media, stones or other sharp objects. Paving fabrics are used as stress absorbing mechanical inter layers in asphaltic overlays Geomembrane Liner TechGeo underliner protection TechGeo surface protection Barrier Techpave nonwoven paving fabrics when saturated with the tack coat functions as a moisture barrier preventing entry of surface moisture into the pavement.

4 Landscape Drainage products are an economical and environmental friendly option any time. Application includes playing fields, golf courses, providing significant & environmental savings by minimizing the cost. A landscape fabric performs four significant functions: weed restriction, soil separation, reinforcement and filtration. TechGeo is highly resistant to acids, alkalies, insecticides, fertilizers and damage from insects and rodents. The weed control fabrics safely eliminate most weeds, while allowing water, air and nutrients to penetrate the plants roots. Roof Garden TechGeo provides excellent drainage over the whole base area of the soil layer in addition to providing additional water proofing protection. This product is also environmental friendly; it absorbs and holds times its weight of water, acts as capillary dispersion layer and performs the function of geotextiles separator filter. Landfill TechGeo nonwovens are used in critical subsurface drainage systems, soil separation and geomembrane liner protection against containment within landfills. These geotextiles provide the required strength and abrasion resistance to withstand installation and application stresses to create an effective, long-term drainage solution.
