Different Functions of GF Geotextile in Civil Projects

GF Geotextile is a versatile material used in civil engineering projects for various purposes. It is a synthetic fabric made from polymers like polyester, polypropylene, or polyethylene. The geotextile has a porous structure, and its primary function is to strengthen the soil and provide stability to the construction projects. In this article, we will discuss the different functions of GF Geotextile in civil projects.

GF Protection Textile

The GF Protection Textile is used to protect sensitive structures like oil and gas pipelines against damage from sharp-edged materials such as stones. The amount of protection is proportional to the thickness and mass of the GF Geotextile.

GF Separation Textile

The GF Separation Textile has fine pores that do not allow the soil grains to pass through, ensuring the integrity and uniformity of different soil layers. It is placed between different soils to improve their functionality and prevent mixing of grain distribution.

GF Drainage Textile

The GF Drainage Textile is used to absorb moisture and allow it to pass through the plane of the GF Geotextile, helping to establish structural stability during and after construction. It is ideal for areas with high water tables.

GF Reinforcement Textile

The GF Reinforcement Textile is used to reinforce soil layers and improve soil shear strength. It is capable of withstanding tension forces, unlike the soil, and can stabilize unstable slopes and embankments. It enhances the bearing capacity of problematic soils by spreading the stresses.

Railway Substructure

The GF Geotextile is used to stabilize and reinforce railways, preserving the shape of the railway substructure and preventing the mixing of base, sub-ballast, and ballast.


The GF Protection Textile is used to protect impermeable layers against installation damages and prevent contaminant leakage. It is used on the base of landfills to prevent soil contamination.

Geomembrane Protection

Geofam needle-punched nonwoven geotextiles are ideal to be used as protective layers for lining systems, offering superior mechanical properties of tensile strength/elongation, static puncture & perforation resistance, as well as long-term resistance to alkaline media.

Dam Construction

The GF Geotextile is used as a filter to separate dissimilar soil layers in earth dams. It helps to improve the drainage capacity of dams and increase the stability of dam slopes.

Asphalt Pavement

The GF Asphalt textile is used as a reinforcement to retard the initiation and propagating reflection cracking between old layers and new overlay. It increases the lifetime expectancy of overlays.

Shore & Riverline Protection

The GF Drainage Textile is used to prevent erosion damage and protect construction projects that are close to riverbanks or shorelines. It is used as separating layers or in the form of geobags.

Pipeline Protection

The GF Geotextile protects the soil and pipe against buoyancy and tensile forces during pipeline construction. It can also protect the pipes from installation damages during construction and after burying the pipes.

Road Substructure

The GF Separation Textile is used to prevent mixing of the grain distribution of base and subbase layers in roadways. It increases the bearing capacity of roadways, decreasing the overall cost of the project.


GF Geotextile is a versatile material used in various civil engineering projects. It provides stability to the construction projects and ensures their longevity. The different functions of GF Geotextile include protection, separation, drainage, reinforcement, stabilization, and erosion control. The applications of GF Geotextile are numerous and can be tailored to the specific needs of a project.
