Geosynthetics are polymeric, innovative, state of the art materials which will improve the whole system performance when in contact with soils. They achieve this objective by applying one or more of the following engineering mechanisms:

• Separation: to stop two adjacent soil layers to be mixed in case of repetitive load exertion
• Filtration: to stop ground water flow through adjacent soil layers
• Reinforcement: material used as a tensile element inside soil to build soil filled structures.
• Sealing: to act as barrier and block the flow of water or gaseous material
• Protection: to resist point load puncture forces that can damage materials and surfaces.
• Drainage: to convey water through a predesign rout and discharge it out of a structure to convey water through a predesign rout and discharge it out of a structure
• Containment: to surround the soil to make a solid & flexible entity moves together
• Erosion control: to stop water or wind eroding soil particles

With above mentioned functions, they could replace many conventional construction material and have been quite a phenomenon in construction industry in recent years. Day by day as infrastructures are growing rapidly around the world, application of these materials had been increasing in past 10 years.

Geosynthetics can be in the form of thick, porous, nonwoven textiles used for separation of different soil layers through to a plastic sheet which stops water infiltration into structures. Some have grid-like forms with openings to interlock with soil particles thereby improving the strength of the soil, which can now resist higher loads. The diversity in geosynthetic materials type and application is increasing and it is very important for clients and their contractors to achieve the best possible benefit from such products by employing experienced, well-educated suppliers and designers like Geotec.
