What is Geogrid?

Geogrid is a type of geosynthetic product used in civil engineering and geotechnics for reinforcing and stabilizing soil and other materials. These materials are made in a grid-like structure from polymer strips or fiberglass, possessing high tensile strength and long-term stability. The main features of geogrid include increasing the bearing capacity of soil, reducing settlement and soil compaction, improving slope stability, and reducing the execution costs of construction projects. Geogrids are commonly used in various projects including the construction of roads, bridges, retaining walls, and marine structures, helping to improve the performance and durability of structures.

Geosynthetics enhance the efficiency of conventional materials, resulting in more efficient, cost-effective, and reliable construction. Since the price of geogrid is lower compared to other materials and it has a longer lifespan and higher efficiency, using this product in construction is very economical.

Geogrid is made from various polymers such as polyethylene and polypropylene and is produced using one of three methods. These three methods are:

Extrusion (perforated and stretched);

Weaving;

Extrusion and welding

Geogrid mesh

The overall shape of geogrid resembles a grid structure with integrated connections, which provides strength and stability to its structure. Geogrids are used in civil engineering to solve problems by stabilizing and reinforcing soil and aggregate materials. The pores present in geogrid sheets allow fine stones to be trapped within them. If the geogrid connections are strong and deep enough, they form an assembly that increases strength and is resistant to deformation by securely holding the soil.

Types of Geogrid

Geogrids are divided into four types, each with different geometric features and designs applicable in various fields and uses. The price of geogrid varies according to its type. These four types are:

Uniaxial

Uniaxial geogrid is stretched in the longitudinal direction, and as a result, stress is only transferred along its longitudinal axis. This type of geogrid has high resistance and tensile strength in the longitudinal direction. Due to the characteristics of uniaxial geogrid, it is used for constructing items such as geogrid retaining walls and is very applicable on sloped earthen surfaces.

Biaxial

Biaxial geogrid is stretched in both longitudinal and transverse directions, and as a result, stress and pressure are transferred in both directions. This type of geogrid has the ability to distribute loads over a wider area than usual and is used for stabilizing foundations due to increased capacity. Biaxial geogrids are the best option for use in roadbed foundations, airport runways, transport roads, working platforms, and parking lots.

Triaxial

With the improvement of the biaxial geogrid generation, the triaxial geogrid entered the market. This type of geogrid has additional diagonal ribs that increase its resistance. Triaxial geogrids are calibrated for the design of pavements, both unpaved and paved roads.

Geogrid-Geotextile Composites

This type is made from two materials: geogrid and geotextile. These types of geogrids serve as effective separators for very challenging conditions.

Applications of Geogrid Sheets

Geogrid sheets have extensive applications in construction. In the past, concrete was used for constructing retaining walls; however, today geogrid is considered one of the necessary materials for building retaining walls instead of concrete. The price of geogrid is lower than that of concrete, and for this reason, the construction cost of walls with geogrid is less than that of concrete. In addition to the impact that geogrid has on construction costs, it also makes walls more stable and resistant to earthquakes.

As mentioned, geogrids improve soil performance by stabilizing and reinforcing it. Therefore, this sheet is also used in the following areas:

It is used in constructing stable platforms on soft ground.

Geogrid sheets minimize the movement of gravel in the construction of high-traffic roads and sidewalks, improving the performance of both asphalt and unpaved roads.

In stabilizing the foundation in highways and railways, geogrid sheets are used to strengthen the foundation and make maintenance of these paths easier and cheaper.

In constructing earthen walls to enhance resistance.

Geogrid is used to support and strengthen embankments and dams to prevent riverbed erosion and flooding.

Geogrid is applied in the protection of pipelines for oil, gas, and water, creating a resistant and non-settling base under the pipes.

In areas where protection is needed to prevent landslides and rockfalls.

To prevent soil erosion until vegetation growth is not hindered.

For access roads to swampy areas. In swampy areas, transporting materials is very difficult and impossible. Geogrid sheets in these areas regulate water movement and reduce soil settlement. Especially if there is a need to construct railway lines and roads in swampy areas, the use of geogrid sheets is essential for creating a suitable base.

This durable product has extensive applications in tunnel construction and drainage. Particularly for mine tunnels, geogrid ensures safety against wall collapses. In old methods, concrete was used to create tunnels, but due to its advantages, geogrid is a better option for tunnel construction.

It serves as a replacement for metal nets to protect the insulation of warehouse roofs, sheds, and sports halls.

For constructing concrete channels for water and sewage, using concrete and geogrid sheets increases the channel's resistance to damage.

The features of geogrid, including environmental compatibility, load distribution over a wide area, high tensile strength, and high retention capacity, have led to its use in pavements and dam construction.

Advantages of Geogrid

Some of the most important advantages of geogrid include:

Geogrids reduce the amount of aggregate needed for construction. Extracting and transporting aggregates for any civil project is very expensive. With the presence of geogrid, the need for aggregates is minimized, which helps conserve land resources and reduces construction costs.

Price of Geogrid Sheets

By using geogrid sheets in construction, projects are completed at a faster pace and enhance the performance of the structure. With geogrid sheets in a structure, repairs and disruptions that may occur over time are significantly reduced.

This product ensures that a structure achieves maximum lifespan and efficiency. In general, considering the price of geogrid sheets, it can be said that this product has very high value and efficiency in civil engineering.

Geogrid reduces soil displacement and increases bearing capacity, which stabilizes construction.

Compared to traditional methods, geogrid has high strength and friction coefficient and greater resistance to corrosion. This high resistance ensures that using it in water projects or roads designed for heavy machinery does not lead to technical problems due to erosion.

Disadvantages of Geogrid

Despite all the advantages of this product and its contribution to conserving land resources, the use of geogrid is harmful to the environment. Because this product is made of plastic, it cannot be ignored that plastics harm the environment. The long lifespan and non-degradability of plastic may lead to future environmental damage. However, due to the widespread applications and numerous advantages of this product, solutions are being sought to address this issue.

Price of Geogrid

The price of geogrid depends on various factors, including its type; in fact, by choosing the type, you also determine its strength, thickness, and tensile properties, thus the price of geogrid sheets in Tehran will also vary. Another factor affecting the price of geogrid sheets is the area. Depending on the type of project, the amount of this product needed will vary.
