What are Geonets? Why is it Important in Construction?

In the past few years, geosynthetics have been gaining popularity due to multiple reasons and their varied benefits. Among these materials are geonets, which are plastic grids used for drainage and reinforcement purposes.

These are essential components of many construction projects, and their installation and proper use have become important aspects of modern construction.

In this blog, we will discuss Geonets and their importance in the construction field.

What are Geonets?

Geonets are three-dimensional grids made of plastic materials that are used in construction projects to provide drainage and reinforcement.

They are commonly used in drainage systems, retaining walls, landfill liners, and other infrastructure projects. These grids have a honeycomb-like structure which allows water passage or other fluid passage.

Similar to geogrid, Geonet is a geosynthetic material. Drainage geocomposites are geonets that have geotextile material coated on both sides of it.

Geonets are a type of mesh made up of overlapping threads or bands that are permanently angled between 60 and 90 degrees (3 to 15 mm). Equal holes are produced, ranging in width from 10 to 200 mm.

They are made by welding threads or bands together or compression of high-strength polyethylene. They are created similarly to geogrids, except during the extrusion process, the ribs are joined together uniformly. A net is continually produced by this procedure.

Types of Geonets

There are two primary types of geonets: biplanar and tri-planar.

Biplanar geonets are flat on both sides and are commonly used in drainage systems, retaining walls, and other infrastructure projects.

Triplanar geonets, on the other hand, have a third dimension that allows them to provide added reinforcement. These are commonly used in landfill liners and other applications where added stability is required.

In addition to the type of geonet, the thickness and size of the grid can also vary. The thickness of the geonet will depend on the intended use and the load that it will be subjected to.

On the other hand, the size of the grid will depend on the application. Herewith, larger grids are being used for drainage systems and smaller grids for reinforcement purposes.

Geonets can also be used in combination with other geosynthetics such as geotextiles or woven geotextiles to provide an efficient drainage and reinforcement system.

Geonets and Geotextile Walls

Geonets and geotextile walls are often used in combination to provide an efficient solution for retaining walls. Geotextile walls are made of woven geotextile fabrics used to stabilize the soil behind the wall, preventing landslides and the collapse of the wall.

Why are Geonets Important in Construction?

Here are the following reasons why Geonets are significant in construction:

1. Provides Proper Drainage System

The use of geonets in construction offers numerous benefits. One of the primary benefits is their ability to provide drainage.

When used in drainage systems, it helps to transport water away from structures, preventing damage from excess water and reducing the risk of flooding.

They can also be used in combination with other geosynthetics, such as geotextiles, to provide an efficient drainage system.

2. Provides Reinforcement

Another significant benefit of geonets is their ability to provide reinforcement. When used in retaining walls or landfill liners, it helps to distribute the weight of the structure evenly, reducing the risk of settling or subsidence.

This makes them particularly useful in areas with unstable soils or where structures are being built on steep slopes.

3. Erosion Control

Geonets also play a critical role in erosion control. When used in erosion control applications, it helps prevent soil loss and the subsequent damage to infrastructure, waterways, and ecosystems.

They also promote vegetation growth, which further reduces the risk of erosion and provides added environmental benefits.

4. Reduces Contamination of Groundwater

Finally, geonets are an essential component of landfill liners. When used in landfill liners, it helps to prevent the escape of contaminants and the contamination of groundwater. They also provide stability to the liner, reducing the risk of damage and the need for costly repairs.

When choosing a geotextile supplier, it is important to consider factors such as quality, reliability, and pricing.

Look for a supplier with a proven track record of providing high-quality geonets and excellent customer service. It is also important to consider the supplier’s location, as this can impact delivery times and costs.

Conclusion

Geonets are an important type of geosynthetic material used in construction. They are versatile and durable, and provide a range of benefits, including reinforcement, stabilization, and filtration.

Whether you need to build a geotextile wall, reinforce a slope, or stabilize a roadway, this can help. Working with a reputable geotextile installation supplier can help ensure that you get the right geonets for your project, delivered on time and at a fair price.
