A geotextile is a permeable synthetic textile that can be used to increase soil stability, provide erosion control or aid in drainage. They are manufactured from a range of polymers and can be used in a variety of civil construction applications.
Woven and non-woven fabrics are the two most common types of geotextiles. They differ in strength, permeability and other properties that can make them a better choice for specific applications. Additional info found at стсгео Екатеринбург.
Generally speaking, woven and non-woven fabrics are stronger than their alternatives and offer greater resistance to wear in a wide range of applications. They also tend to be more hygienic and easier to clean than other materials.
The strength of the fabric at the interface with the soil is dependent on both the type of polymer, strand and manufacturing process. The fabric can be tested by direct shearbox testing or by a combination of laboratory testing and field performance to establish the available strength.
For example, a woven geotextile with an inter-weave ratio of 50% or higher can have a minimum interface strength of tensile or compressive strengths, depending on the type of soil and the design conditions. This is especially true in cohesionless soils, where the maximum shear resistance is governed by the angle of the shear stress to the base.
This is a major benefit of using a geotextile instead of a traditional granular treatment in an erosion control system, ensuring that more granular material is not required and reducing the overall cost of the project. The same benefits can be achieved when a woven fabric is used in a filtering layer, replacing up to 1m of traditional filter material.
Filtration – A major advantage of using a geotextile over a traditional filtering layer is that it allows the water to pass through while retaining some of the soil particles within the fabric. This is essential for filtration to be effective and helps the soil to retain nutrients in the soil.
Separation – The ability of a geotextile to separate different soil layers is an important feature that has helped the construction industry for many years. This is a crucial aspect of road construction and has been shown to help prevent roads from sinking in the mud beneath them.
When using a geotextile in this way, the desired characteristics of the soil are preserved and this helps to preserve the soil’s capacity for drainage, strength and durability. This is especially important for road construction where the different soil layers may be made of a variety of materials.
As a result, the soil can be more easily accessed by other components of the infrastructure, including water and sewers. This has proven to be beneficial for a wide range of civil engineering projects around the world.
The benefits of a geotextile can be particularly valuable in the construction of dams and other earth structures where it is possible for a large volume of soil to be exposed to the elements. In these situations, a geotextile acts as a filtration layer that retains some of the small soil particles while the larger ones can escape through the fabric and into the environment.
