Height Geocell – Ideal for Slope Stabilization

A geocell’s flexural stiffness decreases as the height increases. However, the effect is limited and does not result in a significant increase in bearing capacity.

The pocket diameter and aspect ratio of the geocell also impact its effectiveness. A larger aspect ratio increases the shear strength of the confined soil. This is due to a greater increment of confined sand area.

Stabilizes Soil

The perforation pattern through each cell and weld allows water to drain freely without washing out the material. The textured surface also provides additional material retention, making it ideal for use in slopes and embankments that are prone to erosion. These three-dimensional cellular structures can be expanded during installation to form flexible walls that confine soil, aggregate, or other infill materials, reducing movement and stabilizing the ground. The three-dimensional zone of confinement reduces soil particle lateral mobility, but vertical loading on the confined infill results in considerable lateral stress and resistance at the geocell-soil interface.

In a recent study, the effect of geocell dimensions was investigated in order to determine the optimal design of a soil improvement project. Specifically, the sensitivity of reinforced soil shear strength to a change in geocell dimensions was examined.

A laboratory scale test box was used to investigate the effects of lime stabilization and geocell (with different heights) reinforcement on increasing the bearing capacity of clayey soil with three different water contents. Plate load tests were Height Geocell conducted on the soil and shear force – horizontal displacement curves were plotted for both the reference section and the geocell-reinforced sections. The shear stress – horizontal displacement curves showed that the geocell-reinforced soil had a lower settlement potential and increased the bearing capacity of the soil.

Stain Resistant

Our Height Geocell reduces erosion from weather and traffic, preventing the loss of fill material. Its rhomboidal indentation texture creates friction between the cell and the fill material to help keep it in place and its perforation pattern allows water to drain freely. It is ideal for slopes and embankments prone to erosion as well as roads, driveways, trails and other heavy duty applications.

The ability of geocell mattresses to reduce the stress concentration in the soil below railroad tracks is a major benefit for its wide use in railway engineering. However, the exact mechanism of their action has not been fully understood. It is thought that they are effective because they help to distribute the applied load evenly in both vertical and lateral directions.

Local strain values obtained from plate load tests showed that the settlement potential of geocells decreased with increasing aperture size and geocell height. A maximum value of 78% was achieved for the 440×150 mm type, while only 55% was reached for the 660×100 mm model. The settlement reduction was caused by a combination of factors, including the large aperture geometry and insufficient cell height.

To test the strength of the geocells, four types of tensile testing were performed on the geocell junctions. The peak elongation for the shear and tensile tests increased with clamping distance, but for the peel strength test there was no difference. This suggests that the weld strength of the geocell strip is not limited by the tension in the welded zone.

Durable

Since geocells are a versatile soil reinforcement that improves shear strength, they are extensively used in various construction applications, including pavements, embankments, slopes and retaining walls. However, they are subject to several limitations, including dimensional changes in the geocells that lead to a decrease in interface shear strength. Hence, it is crucial for the design engineer to have enough information about the effect of the geocell dimensions on the shear resistance of the reinforced soil.

Studies show that the performance of geocell-reinforced soils is influenced by several parameters, such as height and pocket size. Generally, the larger the height, the higher the reinforcement capacity. Moreover, the geometry of the geocell layout also plays a significant role in its effectiveness. The layout consists of the cell wall dimensions and pattern, as well as the number of layers, and it must be selected depending on the load requirements.

Similarly, the effect of the geocell dimensions on the stiffness of the geocell-reinforced soils depends on their pore size, surface roughness and other factors. geogrid for retaining walls A coarse surface roughness increases the interface friction between the cell walls and the infill soil and redistributes the shear stress [28]. On the other hand, the flexural stiffness of a geocell grid is also important. This is because it controls the deformations of the cell walls and improves the resistance to cyclic loading.

Easy to Install

With a simple installation process, Height Geocell is an ideal solution for slope stabilization projects. First, you’ll need to mark the slope boundaries using surveying tools and clear the area of any obstacles. Once you have everything prepared, you can begin the installation process by placing the Geocells on the slope. Make sure to properly interlock the panels and secure them with rebar stakes, which are included in each order.

Once you’ve secured the Geocells, it’s time to fill them with aggregate. You’ll want to use a gravel or crushed rock mix to ensure proper compaction and stability. Once the Geocells are filled, you can compact them with a mechanical roller or vibratory plate. Next, anchor the Geocells into place using spikes or pins driven through the cells and into the underlying soil.

It’s important to keep in mind that the higher the Geocell height, the less effective it is. This is because local buckling and straining of the walls reduces the shear strength increment. Therefore, the optimum height of the Geocell should be less than twice the footing diameter.

The shear strength increase of Geocell-reinforced soils can be up to seven times greater than that of unreinforced soil. Moreover, the permeability of the Geocell-reinforced soil is enhanced. Furthermore, the addition of geogrids can further enhance the shear strength of the geocell-reinforced soil.
