Geocells, a unique piece of technology, can help your company’s operations in a variety of ways. The potential applications of geocells include soil stabilization, erosion control, and the development of new surfaces for parking lots and sports grounds.
Introduction to Geocells
The three-dimensional inflatable panels known as geocells are made of high-density polyethylene (HDPE), polyester, or another type of polymer. The connecting strips are expanded during installation to produce the flexible, three-dimensional cellular walls of the infill materials, which include sand, mud, rock, etc. By containing the infill materials by tensile tension and keeping them in place while limiting mobility, a free-draining system is created. This is how geocells enhance the structural and functional behavior of soil and aggregate infill materials.
The perimeter cell walls are subjected to lateral strains when the soil of a geocell is under stress, such as when a load support application is made. While the 3D zone of confinement minimizes the lateral mobility of soil particles, vertical pressure on the contained infill causes considerable lateral tension and resistance at the cell-soil contact.
Geocells are used in construction to reinforce structures for load support and earth retention, limit erosion, stabilize soil, and protect channels. They were first created in the late 1970s and early 1980s. A typical geocell is made of HDPE strips that have been ultrasonically welded together, expanded on-site to form a structure resembling a honeycomb, and then filled. A geosynthetic is, to put it simply, a synthetic material used to stabilize terrain. Nowadays, it is quite easy for you to look for leading geocell suppliers on the internet.
Types of Geocells
To address a variety of problems with different types of soil, geocells come in a wide variety of types and specifications. Perforated and non-perforated geocells are the two types of geocells that perform best.
Water and air can enter perforated geocells through the small holes. This kind of geocell works well for projects like green infrastructure where the soil needs to be able to breathe.
The holes also lessen distortion and increase load distribution. To create cells, many stripes were linked together. The strength of the weld and perforated strip determines the geocell’s integrity.
Landfills are the best applications for non-perforated geocells, which have smooth, solid walls and must keep water out. The smooth walls of the cell, which also keep out water, keep the dirt within. Depending on the application, geocells may occasionally be replaced by geomembranes and prefabricated vertical drains. Clay liners are also quite known nowadays. And you can check clay liner suppliers and Geogrid Suppliers online.
Benefits of Having Geocells
When building structures as part of infrastructure development, consideration must be given to how they won’t impact the environment. Soil stabilization and reinforcement are major causes of worry and potential risks to the long-term stability of roads, bridges, and walkways.
Engineers benefit from cellular confinement systems in a variety of ways, such as lower cost, increased weight-bearing capacity, and improved stability.
The following additional benefits of geocells:
Stabilization and Protection of Steep Slope Surfaces
On slopes, geocells are used to stabilize the surface and stop erosion. In response to the topography, the cells create a three-dimensional wall that prevents soil particles from moving laterally. This stabilizes the slope and lessens the chance of landslides.
Geocells also reduce the amount of stabilizing material required, saving both time and money. They can also be quickly and simply built without the need for heavy equipment.
Geocells are widely used during road building to prevent erosion on steep terrain. Four workers were able to construct geocellular reinforcement on more than 11,000 square meters of one project in just two days.
Providing Static and Dynamic Load Support on Brittle Subgrade Soils
You can also use geocells to support dynamic and static loads on weak subgrade soils. The cells create a three-dimensional grid that lowers the possibility of soil failure by spreading the weight over a larger area. Additionally, water can run through the perforations in the strips, keeping the soil moist and avoiding compaction. This increases soil stability and decreases the probability of failure. Geocells can effectively support heavy loads on delicate soils. Without hurting the subsoil, they could support up to 400 kg of weight per square meter in a single project.
Because they give a flexible base while maintaining the soil, geocells are commonly employed in civil engineering to build roads and pavements. They can distribute loads more evenly, which helps them prevent the bulk of stress cracking that happens on asphalt roads. Additionally, they support keeping the surface level by adjusting for thermal expansion and contraction. This prolongs the pavement’s life and reduces the requirement for upkeep.
Geocells have also been used in the construction of airport runways because of their ability to sustain heavy loads without suffering harm. The cells evenly disperse weight across a large area, reducing breakage and extending the lifespan of the runway.
Due to its various benefits, geocells are an excellent choice for creating paved surfaces and roadways. They are flexible and sturdy, and they can safely support heavy weights. They also help to maintain surface levels and avoid stress cracking. Geocells have been successfully used in the construction of airport runways, making them a flexible solution for a variety of applications.
Improved Slope Protection
Even on steep slopes, a geocell grid is a more resilient solution than mulch matting or stone pitching. Without the use of expensive materials or skilled labor, it stops soil erosion.
The three-dimensional grid of the cells reduces the risk of failure by dispersing the load over a larger region.
Using a cellular confinement system, it is possible to build retaining walls or green slopes in an environmentally responsible way. Without the need for substantial quarrying, the geocells can be filled with plants, concrete, or locally obtained materials like dirt or gravel. Utilizing products created nearby offers a bigger environmental benefit because it reduces your carbon impact.
Today, protecting the environment is a serious obligation. Geocells offer a sustainable and environmentally friendly green alternative.
