Posted on Tags Biaxial Geogrid, Geogird, Geogrid Categories Geogrids, Geogrids

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.

 

Product Types

  • GG 20/20 P (20 kN/m / 20 kN/m)
  • GG 30/30 P (30 kN/m / 30 kN/m)
  • GG 40/40 P (40 kN/m / 40 kN/m)
  • GG 60/60 P (60 kN/m / 60 kN/m)
  • GG 80/80 P (80 kN/m / 80 kN/m)
  • GG 100/100 P (100 kN/m / 100 kN/m)
  • GG 150/150 P (150 kN/m / 150 kN/m)

Packaging and Storage

Bidirectional 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.

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.

Discrete Geomembrane

Posted on Tags Şaşırtmalı Geomembran, Tırnaklı Geomembran Categories Uncategorized

Discrete Geomembrane

Hdpe Based Membrane

Tailed Geomembrane has tabs extending along the roll at certain intervals and allows the concrete to adhere to the geomembrane. This material, which is produced using special molds, is applied under protection concrete in irrigation channels.

It is laid parallel to the channel bed, the protection concrete is poured over the geomembrane and the nails are fixed to the concrete. It also prevents cracking of concrete thanks to its special nail structure.

Application and Usage Areas

With the welding machine, the joints can be joined with minimum labor. Thanks to single or double row welding machines produced with the latest technology, it is possible to make a safe and controllable insulation.

  • Building foundation and curtain wall insulation
  • Terrace and garden terrace roofs
  • Drinking water tanks
  • Water reservoirs
  • Light metal roofs
  • Irrigation channels
  • Ponds
  • Metro stations
  • Railway, subway and highway tunnel projects

T-Grip Geomembrane

Hdpe and PVC Based Membrane

The reason why it is called T-GRIP Geomembrane is that it has T-shaped tabs that continue uninterruptedly along the entire longitudinal line. Thanks to these nails, this product locks onto the concrete it is used in very well and does not leave the concrete.

It includes general HDPE and PVC Geomembrane features. In particular, its resistance to chemicals and its aging life have been increased.

PS NonWoven Geotextiles

PS Non Woven Geotextile is a nonwoven textile product produced in white color by the method of needling pure polypropylene-based fibers much thinner than millimeters and applying heat treatment.

Application and Usage Areas

For Filter Purpose

In engineering applications, when coarse and fine materials are used together, it is used as a filter material in order to prevent the fine material from clogging the pores of the other material or washing out.

GeoTeknik PS Unwoven Geotextile, which is recommended as a filter and bedding material in the effective control and direction of water, is used in the following areas:

  • In the French drain canal
  • Green roof drainage
  • Perforated pipe coatings
  • Vertical applications such as tunnels and retaining walls
  • In coastal structures

For Separation Purpose

  • It is used under the foundation in buildings that are planned to be built on weak soils, preventing the foundation of the building from falling on the ground, providing the stabilization of the ground and reducing the risk of unexpected different settlements.
  • It is used as a filter and bedding material in coastal structures to prevent the displacement of the filling material due to wave movements. It effectively separates the coarse and fine filter materials used in the filling, and prevents the fine material from mixing with the coarse material with the suction power arising from the wave movements.

For Protection Purpose

Due to its high puncture resistance; By being used on the thermal insulation boards in terrace roof applications, it protects the underlying materials from impacts, allows the materials to work differently and prevents the cement slurry from flowing down.

  • Due to its pressure spreading effect, it is used in building foundations to protect waterproofing applications.
  • Protects geomembranes applied in open areas against tearing or damage caused by puncture and excessive friction.

The geotextile, which is brought as a roll on the prepared surface, should be laid taut to ensure full contact with the surface. In order to prevent the geotextile from slipping during filling, it should be applied by overlapping the previous geotextile by at least 25 cm.

Advantages

  • Produced using pure polypropylene fiber.
  • It has a structure that ensures homogeneous distribution of fibers with its frequent needling and superior production technology.
  • With the possibility of production up to 6 m wide, it provides the advantage of fast application with minimum material and labor savings in large areas.
  • Because of the heat treatment applied during production, it is more durable than standard geotextiles.

Packaging and Storage

The materials are shipped in rolls with a width of 1 – 6 m and a length of 30 – 200 m.
Materials should be stored on flat ground and indoors.
Smoking should not be allowed in the storage area.
Stored products should be kept away from direct sunlight, heat and ignition sources.
