Description

Geotextile is absorbent, when used as bottom liner for land it helps to separate, filter, protect and improve drainage.

Geotexitle

Geotextile is made of polypropylene or polyester and its application is usually in irrigation and enviroment activities and transportation infrastructure.

Classification:

+ Woven geotextile

This type consists of horizontally and vertically woven fibers such as polypropylene. The alternatives of this type are usually tested in 2 directions: Machine Direct (MD) and Cross Machine Direction (CMD). Its vertical tensile strength is way higher than its horizontal one. Geotextile is used to create reinforcement cores in ground treatment.

+ Non-woven geotextile

This type shows connected short and long fibers by glue (methodization), heat or needle puncher in no direction.

+ Composite Geotextile

This type is made from woven fabrics and non-woven fabrics to optimize its performance due to including the advantages of both types.

Usage:

+ Seperator

Geotextiles are used to seperate different materials to seperately parts. It helps to preserve the materials’ shape and function under other impacts such as transport activities.

+ Reinforcement

Its tensile strength is so high that we may use to improve soil’s tensile strength by core reinforcement for soil or storage of soil in geotextile bags.

Used for reinforecement

+ Drainage/Reverse osmosis

Geotextiles may be used in drainage system to maintain or even improve soil’s shear strength therefore the whole construction is stable and durable. This application is a great deal for soil that is too moist and sensitive.

Used to prevent sands

Non-woven needle-punched geotextiles are thick and absorbent, therefore their drainage ability is remarkable, vertically or horizontally. It provides solutions for pore water pressure during and after construction, then improve cutting resistance of weak soil.

It is also used in stone carpet and gabion embankment construction.
