Geotextile fabric: uses and applications

Geotextile fabric: uses and applications.

Geotextiles are permeable fabrics consisting mainly of materials such as polypropylene and polyester. Depending on their manufacturing method, they may be woven or non woven, based upon the type of application they are intended for. Woven and non woven fabrics have different production methods. While non woven geotextile fabrics comprise fibres, filaments or other elements that are joined together randomly, in the case of woven fabrics, these yarns, fibres or filaments are intertwined. In this new post, we will focus on the features of applications of woven geotextile fabrics.

Woven geotextile fabrics are defined as any material manufactured by intertwining two or more yarns, fibres, filaments, strips or other elements, usually at right angles, i.e., both lengthwise and crosswise, by means of a textile process. These fabrics are mainly applied in the construction sector. This is therefore the simplest type of fabric manufacturing, also known as the “simple pattern” method, which results in a flat structure.

Woven geotextile fabrics provide biaxial resistance, i.e., in the same direction as they were manufactured. Due to the structure and features of the strips used in their production, they usually have high resistance and low deformation, making them suitable for the reinforcement of roads, slopes, walls and foundations.

According to their nature, we can split these woven geotextile fabrics into the following categories:

• Single filament geotextile fabrics: obtained from the mesh of a single, vast length textile fibre.
• Multiple filament geotextile fabrics: obtained from the mesh of several vast length textile fibres.
• Short fibre yarn geotextile fabrics: produced from the mesh of several cut fibres of varied lengths (up to 15cm).

At Tex Delta, we manufacture woven textile fabrics including, more specifically, the development of DLT GEOFROCE WG, a black colour material comprising highly resistant polypropylene fibres that provide high resistance to traction and low elongation. This type of geotextile fabrics are commonly used in civil engineering projects, as well as different building applications. Our DLT GEOFORCE WG woven material is able to provide the following solutions:

• Reinforcing and stabilising any surface in the construction of roads and motorways, as well as temporary roads
• Expanding the surface in order to increase stability in embankments, slopes and green walls
• Protecting jetties, breakwave and rockfill structures
• Allowing for better water drainage and distribution

DLT- GEOFORCE WG is UV stabilised, thereby increasing its resistance and durability features against damages caused by adverse weather conditions. This woven geotextile fabric has demonstrated a good performance in the event of chemical degradation in acid and alkaline soil areas such as salt marshes. It is also highly resistant to damages occurred during installation while improving the ground’s mechanical properties thanks to its traction and tear resistant features.

Among the most notable uses of woven geotextiles are:

• Separation of different material layers while allowing for water filtration between them.
• Increased ground resistance and stability on building sites.
• Thanks to its smaller pore size, it is capable of creating a filtration layer while preventing the passage of fine soil elements between the different materials, thus preventing ground erosion and degradation.
