Erosion Geomat

Erosion geomat is an environmentally friendly, cost-effective method for protecting slopes. It is also easy to transport and install. Its special circular structure design holds seeds, soil and rocks in place and benefits vegetation.

The resistance of the wires of the geomat was evaluated using TG and DSC tests. The results showed that the samples exposed in the field exhibited lower resistance than those exposed in the laboratory.

Protection of slopes

Slopes are vulnerable to erosion by rainfall, wind, and other natural factors. It is important to protect these slopes from unwanted erosion and ensure that the surrounding vegetation exercises a natural erosion control function. This is done with the use of biotechnical composite technologies such as geomats. The survivability or durability of geomats is an important factor in their application. This study aims to assess the degradation of a three-dimensional polymer backed open structure geomat (EM2, EM3, and EM4) that has been used in a slope at the Simplicio Hydroelectric Power Plant (HPP) Furnas, Brazil. It was subjected to UV ageing for 500 h and 1000 h, and its tensile strength was tested. Its thermal properties were evaluated through differential scanning calorimetry and thermogravimetric analysis.

Compared to traditional shotcrete slope protection engineering methods, the Erosion geomat is more environment-friendly and can be easily installed on steep slopes. Its special circular structure design holds seeds, soil, and rock in place and benefits the surrounding green vegetation. Moreover, its hexagonal wire mesh reinforcement increases the tensile strength of the mat. It also provides filtration, separation, and protection from damage by heavy rain water.

The resulting high-tensile strength of the Geomat makes it an ideal material for stabilizing and protecting roads, railways, river-ways, and dykes. It can even be used to replace concrete, asphalt, and block for slope surface protection. The Geomat’s lightweight and flexible construction helps to reduce transportation costs and allows for quick installation, making it a cost-effective alternative to conventional slope protection engineering.

Stabilization of slopes

Erosion is a natural process that can destroy and damage slopes and embankments. It can be caused by heavy rainfall, runoff, landslides, or even wind and gravity. Steep slopes can be especially dangerous and require erosion control measures to prevent soil displacement and potential avalanches. One such technique is the use of erosion geomats, which are made from non-degradable materials. These mats help to stabilize and reinforce the slope surface by preventing water and wind from reaching the grass roots.

3D Erosion Geomat is a synthetic fabric that prevents surface erosion before the vegetation can grow, making it an ideal choice for permanent slope surface protection. It is a multi-layered structure with up to four layers of UV stabilised polyethylene fibres fused together at the intersections. The voids in the matrix bind and trap soil particles, and support plant growth and anchorage. It is also moisture retaining and nutrient keeping and acts as a good replacement for concrete, rock face or shotcrete.

Despite the fact that erosion increases with slope length on small plots, Wischmeier (1966) found that the increase is not consistent, Erosion geomat as it depends on the type of soil and its water-retention capacity. Moreover, he noted that the effect of slope length on runoff is more important than the effect on erosion. This is probably due to the fact that long slopes have a more concentrated flow and higher turbidity than short ones.

Strengthening of slopes

Erosion is a common problem that affects slopes. To increase the stability of a slope, there are several options for reinforcement: the use of geosynthetic materials such as geotextiles and geogrids, the placement of vegetation to enhance soil resistance to erosion, or the construction of rock or concrete retaining walls. Erosion geomat is a versatile and affordable solution for the protection of slopes.

A three-dimensional erosion control geomat is a non-woven, water-permeable synthetic material that protects slopes from the impact of raindrops, runoff and wind erosion. It also encourages the establishment of plant roots and helps to stabilize the ground. The polymer fibers in the geomat are heat-tangled together to form a flexible, three-dimensional structure.

The survivability of a Geomat is an important factor in its successful application as an erosion-control treatment, especially in areas with a high level of rainfall. This study analyzed the degradation of three Geomats that were exposed to natural conditions and to UV radiation in a laboratory UV ageing chamber. The results of the tests showed that Geomats exhibited good resistance to degradation over six years, even after being exposed to abrasion and high water flows.

The 3D erosion control geomat market is competitive, with key players such as Geosynthetics Australia and Uning new materials dominating the market. Shandong Xingying is another major player in the 3D erosion control geomat market and has witnessed steady growth in sales revenue over the past few years.

Cost-effectiveness

Geomats are a cost-effective solution for slope protection. They are easy to transport and can be easily installed on a slope using simple equipment. They are also very versatile and can be used to replace shotcrete in a variety of applications. Their special circular structure design holds seeds and soil in place and benefits vegetation growth. They can be used for a wide variety of slopes, including freeway embankments, railways, and riverbanks.

A geomat is a non-degradable, synthetic material composed of heat-tangled filaments. It can be placed on steep slopes to protect them from erosion. plastic geogrid Its densely fused strands imitate the role of a root matrix, binding and trapping soil particles and fertile humus. This helps to reinforce the vegetation and improve its performance against erosion [1].

The 3D Erosion Control Geomat Market is a competitive industry with many key players. Some of these include Geosynthetics Australia, Uning New Materials, and Shandong Xingying. These companies are investing in research and development to produce innovative products and technologies for the erosion control market.

A recent study found that a geomat, if properly installed, can reduce the amount of eroded soil by more than 50% compared to unprotected banks. In addition, it can help stabilize the surface of a slope and encourage vegetation growth. The study analyzed different sections of three experimental units located on the reservoir margins of HPPs. The sample from section VG2 showed significant variations in the DSC analysis and sediment disposition on the reservoir margin.
