Geotextiles

WHAT IS
GEOTEXTILE ?

“Geotextile” can be separated into two terms, “geo” and “textile”. The word “geo” comes from the Greek meaning “earth”, so geotextiles can be defined as the permeable textile materials that are used in combination with soil or any other civil engineering material.

ZARIFTEX GeoTextiles are made of:
Polyester
Polypropylene
• Polyester + Polypropylene (combination of materials varies based on the order)
Width: Up to 6 m
Weight: 200 gr/m2 to 1200 gr/m2

Since polypropylene geotextiles perform well when exposed to water and other inorganic compounds, they are for uses such as pond liners, bank weed control, liners for garden fountain systems, filtration, dividers in ponds, pile wraps, lagoon liners, turbidity curtains, or as in this case, and an artificial habitat.

APPLICATIONS

Application of Geotextiles based on polymer and polypropylene due to 6 features (Drainage, Protection, Erosion control, Separation, Filtration, Reinforcement) would be classified in civil works and roads. it has been explained that woven and non-woven geotextiles, are being used in different industries more day by day.

FUNCTIONS

Separation
For separation the fabric is laid between two layers of different materials, such as two different soil types, or new construction and soil, or new and old pavement.

Drainage
Geotextile drainage materials can help gather water or gas and then transport it along its plane, therefore providing seamless transmission.
This drainage function is highly effective in chimney drains as well as dimpled strip drains.

Stabilization
In stabilization, the fabric is applied on top of a material that is highly compressible. Most often, this material is wet, soft soil. Here, the geotextile allows water to seep from the soft soil to draining materials.
As a result, it consolidate the basement layer, thus strengthening it and making it a more trustworthy base.

Filtration
Geotextile filtration allows the passage of water from covered layer.
The goal of this application is to remove water while preventing soil and or any other fine particles from passing through.
This is achieved in combination with a filter behind the geotextile.
In this process, water is removed, rather than being filtered into a different material.

Reinforcement
In reinforcement, the geotextile or mesh act as a source of strength instead of strengthening the bottom layer like in stabilization. Using geotextile as reinforcement is usually in the following areas.
• Sleep slopes: allows the building of steeper slopes as well as save the needed land surface and seal material.
• Retaining walls: in this application, the retaining walls with geotextile materials accommodate settlements much effective than traditional construction materials.
• Control water erosion of bay shores, sea embankments.

Moisture Barrier
Functioning as moisture barrier, the geotextile is placed to block water rather than allowing water to pass through. This is accomplished by applying an asphaltic suspension.
as a result, the fabric becomes impermeable and suitable for use in construction projects such as pavement rehabilitation.
