GT Braided Geotextile

GT Braided Geotextile is a knitted geotextile produced by knitting method, using pure polypropylene yarn, one in the direction of production and the other in the direction perpendicular to production.

Usage Areas and Advantages

  • In structures to be built on soft and weak soils, it increases the bearing strength of the ground.
  • Used as a reinforcement layer on roads due to its low elongation under high tensile force. It minimizes deformations such as uniform seating and pitting caused by vehicle wheels.
  • By preventing the sub-base material from mixing with the ground, it preserves the load-bearing capacity and minimizes the material losses used in the filling.
  • Prevents deterioration on the ground, especially in road constructions, by immediately absorbing some of the load and creating opposite forces at the edges of the local collapse region.
  • For slope stability, especially geogrid reinforced GeoArme structures are recommended, but knitted geotextiles can also be used. This practice prevents soil loss during floods.

Packaging and Storage

It is shipped in rolls with a width of 5.0 – 5.25 m and a length of 100 m.
Materials should be stored on flat ground.
Stored products should be kept away from heat and ignition sources.

Geocomposites

Geocomposites are materials developed for double or unidirectional geogrid needs in various infrastructure applications, offering separation, drainage and strength properties with a single product. It is formed by combining polyester geogrids, which are knitted in a rectangular shape and covered with PVC, with geotextile during production. It provides high performance thanks to a specially designed sewing method so that it can be more robust at the node points.

Application and Usage Areas

Geocomposites produced unidirectionally or bidirectionally according to the need in the project, in general; It is designed for stabilization between fill layers of different grain diameters or between weak soil and granular fill.

  • Runway, apron and taxiway foundations at airports,
  • Construction of foundation drainage system in airport projects
  • In railway new line construction applications
  • In high speed railway construction applications
  • Applications to be made on weak ground on highways,
  • Filling works of highway widening projects
  • As a deck in ground pile applications
  • It is used in the foundations of container storage areas, ports and industrial structures.

Advantages

  • While it offers all the features of geogrids, it also works for drainage and separation purposes.
  • Providing the performance of two separate products in a single product, it provides ease of application and labor savings.
  • Applied on weak soils with water problems, it prevents the granular filling from sinking into the bottom layer of the ground.

Biaxial Geogrid

Biaxial Geogrid are high-strength materials developed for bidirectional geogrid needs in various applications of civil engineering. It is produced by knitting polyester microfibres in the form of rectangles and covering them with PVC. It provides high performance thanks to a specially designed sewing method so that it can be more robust at the node points.

Application and Usage Areas

Bidirectional Geogrid is a high strength geogrid specially developed to be used in the following areas for stabilization purposes where strength is required in both directions.

  • In airports runway, apron and taxiway foundations providing higher bearing capacity
  • In the prevention of local settlements in applications to be made on weak ground on highways by reducing the amount of foundation and sub-base filling
  • Filling works of highway widening projects
  • Soil improvements to reduce the amount of ballast and sub-ballast in order to prevent potential settlements in railway applications on weak ground
  • It is used in the foundations of container storage areas and industrial buildings, to increase the bearing capacity of heavy foundations and to prevent local settlements.

Advantages

  • Allows the filling layer to be laid on the weak ground to be laid in a thinner thickness.
  • A platform is created with the filling formed on weak soils and prevents different settlements.
  • It increases the bearing capacity of the floor by being applied in layers on weak floors.
  • Reduces the amount of excavation in the existing ground that is undesirable.
  • It is durable, long-lasting, reliable, low cost and resistant to seismic and dynamic loads.

Uniaxial Geogrid

Uniaxial Geogrid are high strength materials developed for unidirectional geogrid needs in various applications of civil engineering. It is produced by knitting polyester microfibres in the form of rectangles and covering them with PVC. It provides high performance thanks to a specially designed sewing method to be more durable at the knots.

Uniaxial Geogrid are knitted type geogrids with tensile stress in one direction significantly higher than tensile stress in the opposite direction.

Application and Usage Areas

Unidirectional Geogrid is used in applications such as slope stabilization and reinforced retaining structure systems (GeoArme) where strength is required in one direction.

(GeoArme Retaining Structure Systems) general usage areas of reinforced retaining structure systems with fast and economical application possibility, safe earthquake behavior, flexible structure, resistant to settlements and at the same time aesthetic appearance:

  • Divided road widening works
  • On the approach walls of bridged intersections
  • In places where expropriation will be made
  • Works to gain space
  • On the bridge edge footwalls
  • On bridge elevation walls
  • Used in park and garden walls.

Advantages

One Way Geogrid; It is durable, long-lasting, reliable, low-cost and resistant to seismic and dynamic loads. When the fill or granular material is laid on the geogrid, the grains of the fill material are fully interlocked with the openings of the geogrid.

One-Way Geogrid ensures that this tension is met inside the pores, forming a unity with the filling material. Thus, the tensile and shear stresses on the ground are met by the geogrid, forming a reinforced platform.

Packaging and Storage

Unidirectional Geogrid is produced in rolls with a maximum width of 6 m and generally 100 m in length. Each roll is shipped in a UV-protected package.

It is recommended to put up to 6 rows in case of stacking, and if the roll widths are shorter (up to 2 m), it is recommended to load and store the rolls vertically.
