Surface erosion control
With the company surface erosion control all soils subject to crumbling caused by atmospheric events (such as rain, wind, ice) or by close contact with water flows (such as rivers or lake and sea shores) are stabilized, and natural revegetation is encouraged.
Vegetation, in fact, plays an essential role in prevent erosive phenomena and hydrogeological risks and to ensure the solidity of the land on a slope or bordered by a watercourse.
Soil erosion control techniques
Erosion phenomena occur when the ground deforms and causes bumps, cracks or
cracks, due to compressive and tensile stresses. Reinforce the soil with elastic elements such as anti-erosion geocomposites è one of the major preventive and control systems, along with the sowing and planting of new vegetation.
In full compliance with the principles of naturalistic engineering, the inclined extrados of an earthen structure can be consolidated by planting or sowing a adequate root system of essences (possibly native), thus giving rise to extensive roots capable of holding the clods firm.
The initial stage of plant germination it's very delicate. Some areas are particularly sensitive to surface erosion phenomena – such as landslides, small mudslides, formation of gullies – and more exposed to the consequences of rainfall and the exceeding of Atterberg limits (which determine the resistance, compressibility and permeability of fine-grained soils and the stability of slopes). Atmospheric events, therefore, can compromise germination and the correct growth, reducing the possibility that vegetation can become a solid surface armature for the slope.
Anti-erosion geomats
The three-dimensional geomat prevents surface erosion of the most delicate soils and in Sineco we can offer you specific products to control this phenomenon. It is applied to the soil before the germination of the plants for support their trainingThe anti-erosion geocomposite can contain two widespread phenomena:
- it “splash erosion” (i.e. impact erosion)
- “soil liquefaction”.
To understand better, we need to consider the impact of a drop of water on the groundDepending on its size and the force of impact on the ground, the drop disperses its energy
kinetics through a spray crown that distributes other smaller drops, eliminating some soil particles. If the plane is inclined, the latter will move downwards, away from the impact point (splash erosion). If the soil, on the other hand, has a high absorption capacity, the drop of water will be absorbed, giving rise to the liquefaction of the soil, making it become increasingly liquid and fragile.
The anti-erosion geomat protects the soil surface from these damaging effects. permeable, flexible, three-dimensional structure, made up of small alveoli of monofilaments It has a shape that allows it to be easily filled and saturated with the same soil, preventing it from slipping.
Our products for the control of surface soil erosion
SINMAT
An three-dimensional geomat made of extruded monofilaments in synthetic material and characterised by a three-dimensional pyramidal structure.
Indicated for the permanent protection of the land from erosive actions caused by atmospheric agents or by proximity to water flows (such as rivers or lake shores). It also prevents landslides and hydrogeological disasters.
An easy to install, cheaper solution with a lower environmental impact compared to traditional alternatives.
Applications of our geomats for surface erosion control
Anti-erosion geomats of Sineco International are indicated for different applications. Among the most important:
Anti-erosion geomats for civil engineering
They ensure the control of soil erosion and the correct functionality of infrastructures designed in the civil sector such as: road construction, road embankments, trench edges, slopes, tunnels, bridges and viaducts that require revegetation.
Anti-erosion geomats for nature and gardening
They increase the protective and mechanical resistance capacities of the soil, stabilizing it. Indicated in the naturalistic field for revegetate the area subject to erosion, preventing the phenomenon.
