Geomat – A Three-Dimensional Erosion Control Carpet
Geomat is a three-dimensional synthetic erosion control carpet that is easy to install. Its densely fused strands imitate the root matrix, binding soil particles and allowing grass or plant roots to sprout.
The patented system is sloped towards a drain to provide optimum filtration and waste water containment. Its aluminum framed structure is RIDEM approved for sewage connection.
Erosion protection
Erosion on slopes or embankments is a serious problem that causes soil loss, damage, and pollution. It can be prevented by the use of geomats, which are made of water-permeable synthetic materials. They are especially useful for bare soils that need to be protected from the degrading impacts of rain, drainage water, wind, and waves.
Reinforced geomats reduce the amount of eroded soil by over 50%, compared to unprotected banks. They also allow the retention of a thick surface layer, even on steep non-water permeable slopes. Geomats can be used to stabilize soil surfaces before re-cultivation. They are also light and easy to handle.
In the present work, thermoanalytical analyses of the erosive potential of geomats and their application on reservoir margins were performed using differential scanning calorimetry (DSC). The results showed that the degradation of geomats was not significant when installed under natural conditions. However, when they were applied in combination with sack gabion on the reservoir margins, the erosion control effect was better.
Geomats are 3D meshes with voids of over 90%, and are based on polyethylene fibers Geomat fused together at their intersections. They can be molded into various shapes, including curves and channels. They can also be cut into different sizes for specific applications. The voids between the filaments promote the development of vegetation and trap sediment. They can also provide support for growing roots and anchor them.
Linear protection
A geomat is a synthetic product shaped as a three-dimensional erosion control carpet, which helps to strengthen the slope’s endurability and prevent landslide potential. Its waterproof structure keeps the surface of soil intact, allowing for plants’ root sprout to grow without disturbance. In addition, it can be used in a variety of projects, including erosion and linear protection, as well as to stabilize the soil.
Studies of the geomat’s degradation were performed in various conditions, such as shaded areas, grass cover, open sun exposure, and under a landslide. The results showed that the tensile strength of the constituent wires decreased with time. However, the results could not confirm the expected greater loss of elasticity for samples exposed to sunlight. This result is likely due to photo-oxidative conditions that are not replicated in the laboratory.
ACEMat is a high-strength mat that can replace shotcrete for slope protection and stabilizes the soil. Its special circular structure design holds seeds and soil in place and benefits vegetation, which makes it an excellent choice for protecting a freeway embankment. Its water-permeable structure also protects the soil from direct wash by rain or surface runoff and keeps it steady. Moreover, it is easy to cut, install, and anchor. It is also highly resistant to abrasion. In fact, it has withstood multiple typhoon attacks since its construction in 2018. It also reduces maintenance costs.
Water retention
Geomat is an innovative product shaped as a three-dimensional erosion control carpet, which strengthens the subsoil’s endurability to avoid landslides and supplier geotextile slope failure. It is used in hydroelectric power plants to control erosion of reservoir margins. This reduces energy losses and helps the vegetation to develop roots in eroded areas. It is a cost-effective solution that does not require special equipment or expert workers.
The patented product’s unique design allows grass to grow through its structure, leaving 90% of its space free for soil, gravel, and stones. It also effectively addresses rock slope and high and steep slope protection challenges.
It is important to scarify the drain field base well before installing the GEOMAT laterals. This will help ensure that the laterals are placed in uniform trenches. Additionally, it will help to keep the drainage system from becoming clogged with sediment. It is also recommended to install float switches to control the high water alarm, pump on/off, and low water alarm/redundant off.
The thermal analysis of the Geomat sample from CP and SP shows that there was no degradation in the material for the crystallization temperature (Tc). However, the heat of fusion (DHm) values and percentage of crystallinity showed a significant variation. This could be related to the application conditions, as the geomat was submerged for most of the time in the reservoir margin.
Eco-friendly
Geomat is a highly-effective and eco-friendly solution for erosion control and slope stabilization projects. It prevents soil erosion, reduces sedimentation, and promotes vegetation growth. In addition, it protects water bodies from contamination and maintains ecological balance. Furthermore, it minimizes maintenance and operational costs by reducing the need for excavation and construction.
Its three-dimensional matrix is designed to protect bare soil from raindrops, run off and wind erosion while allowing the surface soil to be cultivated. Once vegetated, it reduces the amount of eroded material by over 50%. Furthermore, it has a long life and is resistant to UV radiation, chemicals, and biological degradation.
In the mining industry, Geomat is used to stabilize slopes and prevent landslides. It is also utilized by electric power companies to reduce sediment runoff and improve water quality. It is also used by industries that work with hazardous materials to contain and recycle wastewater.
This eco-friendly product is available in different sizes and thicknesses to accommodate any project needs. Its lightweight construction and easy installation make it a cost-effective solution for any project. In addition, the patented system is easily cleaned and requires only annual maintenance (depending on usage). All residual waste is contained, disposed of, and manifested in accordance with local and federal EPA guidelines. The system is a great option for many industries that require environmentally friendly, long-term solutions for erosion control and slope stabilization.
