Reinforcement of granular layers with geogrids FORTGRID UX for walls on reinforced soil

Reinforcement of granular layers with uniaxial geogrids

 

MURO CAPAS GRANULARES 123The reinforcement of granular layers with uniaxial geogrids is a geotechnical engineering technique used to improve the stability of soils and structures built on them. Uniaxial geogrids FORTGRID UX are a high-strength polyester mesh that is layered between granular soil layers. The geogrid provides additional strength to the soil layer, which improves its ability to withstand horizontal and vertical loads.

geogrids FORTGRID UX  are made up of a regular network of integrally connected elements (ribs) with openings that allow interlocking with the surrounding soil.

The ribs are made from high tenacity polyester multifilament fibers PET, a special synthetic polymer for the manufacture of geosynthetics that owes its special characteristics to its higher level of polymerization compared to other resins such as polypropylene PP, polyethylene PE and high density polyethylene HDPE.

During the production process, the polyester granules are transformed into multifilament fibers that resemble small high-strength strands called G5 Multifilaments. This process includes a first extrusion stage through which the virgin material is converted into fine continuous filaments as shown in Figure 2 and a second stage in which they are subjected to a tension and compression process that confers special mechanical characteristics such as long-term mechanical stability (low creep), high tensile strength and high deformation modulus.

geogrids FORTGRID UX  are constructed from the multifilaments forming the ribs or straps by means of state-of-the-art industrial weaving techniques, arranging them conveniently both longitudinally and transversally to achieve the required strengths. At the joints or nodes, they are interwoven to achieve the resistance required by the mesh to achieve an adequate interaction with the soil. Once formed, they are coated with a copolymer that increases their dimensional rigidity and increases their resistance to installation damage, UV rays and aggressive chemical environments.

 

Benefits of using uniaxial geogrids in reinforced soil walls

Below are the benefits of using Uniaxial geogrids to reinforce walls in reinforced soil.

  • Uniaxial geogrids are commonly used to reinforce retaining walls, embankments, roads and other structures that are built on soft or unstable soils.
  • geogrids FORTGRID UX are manufactured from high-strength polymers, such as polyester, and feature multiple tensile strengths to meet the specific needs of each project.
  • Uniaxial geogrids are installed in layers between granular soil layers 
  • The benefits of using uniaxial geogrids to reinforce walls in reinforced soil include increased load-bearing capacity, increased stability, and increased durability.
  • Walls in soil reinforced with geogrids FORTGRID UX Are an efficient alternative to optimize the use of full materials and available areas in infrastructure projects.
