Geotextile Manufacturers and Suppliers in Turkey

A geotextile is a permeable textile used in contact with soil to perform one or more of the functions of separation, filtration, drainage, reinforcement and protection. It is mostly made from polypropylene or polyester, as a woven or a needle-punched nonwoven. In Turkey, the needle-punched nonwoven type is also searched for as “geotekstil keçe” (literally “geotextile felt”), so you may meet that term on supplier sites. This page lists companies that make and supply geotextiles for projects such as roads, railways, drainage and landfill sites. Other geosynthetic products such as geomembranes, geogrids and geonets are not geotextiles, so state the product type separately in your inquiry. Geotextile filter fabric used in ground drainage is on this page; for industrial dust and air filtration see industrial filter fabrics. For raw surfaces see nonwovens, for high-strength wovens see technical fabrics, and for the parent sector see technical textiles.

Define the function first

Choosing a geotextile starts with what the surface must do: separation, filtration, drainage, reinforcement or protection. The function determines the product type and strength class. Ask for the following in your inquiry:

• Weight (GSM) and thickness
• Tensile strength (kN/m) and elongation at maximum load (EN ISO 10319, wide-width tensile test)
• Static puncture resistance, CBR (EN ISO 12236)
• Water permeability normal to the plane (EN ISO 11058)
• Characteristic opening size (EN ISO 12956)

Request quotes against the values and lower limits that the project specification sets.

Ask a geotextile supplier about the declaration of performance and roll logistics

• Producer or reseller? To know your access to lot-level test reports and who is responsible for technical support, confirm whether you are dealing directly with the producer.
• CE marking and declaration of performance: Check that the declaration of performance names the product standard that suits your application (for example EN 13249 for roads, EN 13252 for drainage systems) and the current edition of that standard. For Turkey, the basis is the Construction Products Regulation (Yapı Malzemeleri Yönetmeliği; Official Gazette, July 10, 2013, as amended, in Turkish).
• Roll size and weight: Roll width, length and weight determine the unloading equipment on site and the shipping. It helps to talk to logistics companies early.
• Stock and lead time: Large project quantities may need line planning. Ask whether you can split the delivery into lots.
• Samples: Compare a sample taken from the edge of a roll with the specification values; verification by an independent testing laboratory can be requested.
• Minimum order (MOQ): It is set per roll, pallet or project; make clear in the quote what the unit is (rolls or m²).

Polymer, strength class and freight set geotextile price

Polymer raw material, GSM and strength class, roll size, documentation and test cost, freight distance and project quantity set the price. Because geotextiles are bulky and heavy, compare the total cost at the delivery point (state the Incoterms rule). When you compare two quotes at different GSM, look at the price for the same strength value, not at the price per m².
