Black Color Geocell
Black Color Geocell is an innovative geotechnical cellular confinement system that has proven itself in many different construction projects. When used correctly, it can strengthen soil while providing separation and stability for aggregate infill layers.
Several studies have shown that a Geocell layer can reduce bearing pressures by dispersing load. To make this happen, it is important that the correct construction techniques are followed.
Textured to Keep Fill in Place
The TechnoEarth Geocell is a three-dimensional geosynthetic material that provides load support and stabilization to base layers of gravel, rock, soil or sand. This greatly improves Black Color Geocell a layer’s lateral strength and prevents fill from shifting or being pushed sideways, resulting in less erosion. This allows a much thinner base of materials to be used which saves time, money and resources.
This is an ideal product for livestock areas, trails, and any other area where costly erosion can occur. Its rhomboidal indentation texture (1.5+/-0.1mm) creates friction and helps keep the fill in place. Additionally, it also prevents the buildup of mud, which can hinder animal movement or make conditions for vehicle traffic unsafe.
A 4″ depth of aggregate or geocell, with a non-woven or woven geotextile, is a great option for a stable surface for animals and vehicles to move over, without the worry of sinking or damaging the subgrade. This reduces the amount of expensive base materials needed, increases lifespan and minimizes surface rutting.
This product is easy to install and comes in different sizes depending on your application. For light traffic, a 2″ Geocell is recommended, while the 4″ version is perfect for driveways or areas that will be subject to heavy or repeated vehicle traffic. The Black Color Geocell can be filled with soil, sand, crushed rock or concrete infilling, and works for sloped and flat areas.
Great for Erosion Control
Erosion is an ongoing problem on sloped ground, and can cause problems for people living around it. Geocells can help prevent erosion by holding the soil in place. They also make it less likely for soil or other materials to wash away in rain storms.
One of the best uses for geocells is in building access roads for farms. They can protect the dirt road from erosion so it lasts longer, and can keep the soil from washing away underneath the surface. They also can be used to stabilize muddy areas in pastures and fields, making them safer for animals and heavy machinery.
They are also used to reinforce slopes and embankments. The honeycomb structure helps them resist erosion from water and wind. They can even be used to prevent erosion in mining contaminants ponds, landfills, and lagoons.
Lastly, they can be used to create stable and permeable slopes for green walls and Nonwoven Fabric Bag retaining wall systems. These can be built without considerable quarrying, reducing construction costs and environmental impact.
The cellular confinement system that geocells use makes them an ideal option for stabilizing soil and preventing erosion. They can be filled with gravel, sand, or other materials to improve stability and prevent slumping. The perforations and textured surface increase the friction angle of aggregate infill against the cell walls, reducing downslope movement and load distribution. They are also easy to install, which reduces construction time and cost.
Strengthens Base Layers
The Black Color Geocell is a three-dimensional cell confinement system that can add significant strength and stability to base layers of soil, gravel, sand or rock. Once filled, the Geocell will prevent the material from shifting sideways under a heavy load. It also significantly reduces erosion caused by weather and heavy or repetitive traffic.
It works by increasing the surface friction of the aggregate infill with the geocell walls and the rhomboidal indentation texture. This increases the aggregate lockup and distributes load over a wider area. It also decreases the vertical differential settlement into soft subgrades, increases shear strength and improves load-bearing capacity.
This product is welded together by the use of ultrasonic welding machines into a three-dimensional network structure that can provide load support and stability to base layer materials. It can also be used for erosion control and is easily folded for transportation.
To install the Geocell, prepare the area by removing any vegetation and grade as necessary. Place a non-woven or woven geotextile under the Geocell for separation, reinforcement and weed control. Next, stake out the Geocell with rebar or large anchor pins (using 18″ J-hook rebar anchor stakes). Finally fill the Geocell with your desired soil, gravel, sand or rock. Generously wetting the material and using a compactor is highly recommended to reduce settling after installation.
Reinforces Soil
Geocells improve the strength of soil to resist lateral and shear forces, increasing its bearing capacity. They also help control the movement of soil, decreasing rut depth and surface roughness on pavements and other traffic infrastructure. This helps to reduce maintenance costs, prolong the lifespan of infrastructure and increase traffic benefit ratio (TBR).
The performance of geocells is mainly determined by their height, overall width, pocket size, shape, and pattern of arrangement. The limiting factors are the width of geocell layers extending beyond the stressed zone and the amount of stress developed in the soil. A decrease in the pocket size increases the additional confinement offered by the cell wall and results in increased apparent cohesion of the geocell-reinforced soil composite.
Using a combination of geocell, micropile and geogrid to reinforce a slope has been shown to be a very effective method to mitigate slope failure issues. This is because the geocells act as a mattress that distributes the load evenly over its area and prevents the failure of the soil. In addition, the use of a geocell in conjunction with a micropile has been shown to be able to resist the lateral and shear forces imposed on the slope and increase its factor of safety. The technique has been used to stabilize the dynamic Himalayan slopes of Nepal.
