Geonet – A Multifunctional Geosynthetic With Drainage and Filtration Capabilities
Often used in conjunction with other geosynthetics, such as geotextiles, geogrids and geomembranes, Geonet provides many benefits such as drainage, soil stabilization, and filtration. Its multifunctional design makes it preferred harvest for construction and engineering purposes.
Geonets offer a significant advantage in drainage by improving subgrade drainage capabilities and preventing water buildup. Additionally, they enhance load-bearing capacities and stability by distributing loads evenly, minimizing deformation and settlement.
Reinforcement
A geonet can help stabilize soil and prevent landslides in a wide variety of applications. It can be used to build a geotextile wall, reinforce a slope or stabilize a road. It can also be used to protect dams and rock surfaces. In addition, it can be laid in the foundation of a bridge to distribute the load and improve its stability.
It can be found in many different shapes and sizes. The most common types are biplanar and triplanar geonets. The biplanar type has two sets of parallel central ribs at different angles and spacings. The triplanar type has three sets of parallel central ribs and is much more stable than the biplanar type.
Geonets are commonly used to facilitate drainage in low-permeable soil. They have a high tensile strength and a good pore space. This makes them an ideal choice for reinforcement.
In a study, it was found that the cyclic behavior of an unreinforced clayey soil and a geotextile-reinforced clayey soil showed a decrease in resilient deformations and an increase in permanent deformations. The results showed that the geonet reinforcement improved the bearing capacity of the soft soil.
The improvement of the bearing capacity of the geonets was attributed to the ability to disperse the soil stress, limit lateral displacement, and improve the reinforcement stability. Moreover, the geonets were able to increase the resistance to sliding and the bending strength of the footing.
Drainage
Whether you’re looking to build a geotextile wall, reinforce a slope, or stabilize a roadway, working with a reputable geosynthetic installation supplier can help ensure that you Geonet get the right materials at a fair price. Among the most popular geosynthetics used in construction, geonet is a multifunctional product that offers both reinforcement and drainage capabilities.
Its unique diamond structure is crafted by crossing two sets of polymeric grids at a continuous angle, allowing for uniform channels and density, which helps improve drainage capacity. This means that water flows through the material easily, preventing it from accumulating and causing damage to the surrounding soil.
Additionally, geonets are crush-proof and have high tensile strength, which increases their load-bearing capabilities. This makes them an ideal choice for applications that require added stability, such as retaining walls and landfill systems.
Another benefit of geonet is its ability to separate soil layers and reduce the likelihood of differential settlement. This function is important in landfills, where it can help prevent leachate from mixing with the surrounding soil and contaminating the environment. Furthermore, it can also be used to reinforce steep slopes in landfill cells and prevent landslides.
Filtration
The grid-like structure of geonets allows water and other liquids to pass through while retaining soil particles. This helps prevent clogging in drainage systems and maintains their long-term performance. This filtration capability is especially important for landfill leachate collection and subsurface drainage applications.
The durability and longevity of geonets help reduce the cost of project construction and maintenance. They are also chemically inert and resistant to degradation from exposure to UV radiation, moisture, biological factors, and more. The versatility and adaptability of geonets make them a great alternative to aggregate drains, as well as a cost-effective substitute in double-lined containment applications.
In addition to improving subgrade drainage, geonets can provide soil reinforcement and reinforcement for structures such as retaining walls, embankments, and slopes. They can improve the load-bearing capacity of the soil and reduce differential settlement by distributing loads more evenly, helping to minimize deformation and subsidence.
Layfield’s HydraNet® geonets, which are manufactured in North America, are ideal for use in highway and railway subgrades. Their durable design and effective transmission of fluids and gasses help to protect the subgrade from water accumulation, which can cause pavement and rail deformation and deterioration. Geonets can also be used to stabilize and prevent landslides in river and reservoir embankments, and in coastal engineering. In these applications, laying geonets on the slope can help prevent landslides and buffer the impact energy from breaking waves.
Erosion Control
Designed to provide a reinforcement layer and prevent soil erosion, geonets have multiple applications. They help enhance stability and longevity of civil engineering projects by improving subgrade soil conditions, facilitating drainage, and providing effective filtration. They are versatile and can be cut and shaped to fit specific project needs.
Geonets are constructed with parallel sets of ribs, creating a three-dimensional bi-planar core that geocell manufacturer enables liquid and gas transport. They are often laminated with geotextiles on one or both sides, allowing for enhanced hydraulic flow-rate performance, known as transmissivity.
Moreover, they can be used to protect slopes and embankments from erosion and to control soil water pressure in retaining walls, canals, dams, river banks, and road slopes. The net-like structure of these geosynthetic materials also makes them ideal for use in preventing rockfalls, and averting damage from heavy traffic loads or snow and ice.
Geonets can also be paved in the road slope to ensure safety and to prevent the rocks from falling which avoids hurting any person or vehicle. It is also a perfect material to be used in road construction, to warp ballast to prevent loss of ballast and increase stability of the road roadbed. In addition, it can be paved in the backfill of a retaining wall to disperse soil stress, avoid lateral displacement and increase stability of the retaining wall.
