Geotextile Bag: Functions and Types

Coastlines and riverbanks affected by abrasion can suffer harmful environmental impacts. Many efforts have been made to tackle coastal abrasion and riverbank erosion, one of which is using the geotextile bag as a breakwater and water barrier.

As the name suggests, this product is shaped like a bag or sack and made of geotextile. The material is strong and weather resistant, so it can be used over the long term. To learn more, read the overview below.

Geotextile Bag System Functions

As is well known, coastal areas are highly vulnerable to abrasion from waves pounding continuously. Likewise, riverbanks are prone to landslides and even flooding due to erosion.

In addition, some landslide-prone areas can experience landslides due to high rainfall and deforestation. The right measures are therefore needed to prevent erosion and landslides.

One solution considered practical and effective is the geotextile sand bag, made of woven or non-woven geotextile. The functions of geobags include:

1.     Preventing Abrasion and Erosion

As mentioned, geotextile fabric bags can be the most practical solution to prevent and tackle coastal abrasion and erosion caused by river currents and high rainfall. Geobags are usually filled with sand and placed on beaches or riverbanks.

Geobags are also installed in several landslide-prone areas. Neatly and tightly stacked geobags help break sea waves, minimizing abrasion. The same applies when they are placed on riverbanks scoured by currents.

2.     Preventing Landslides and Floods

Installing geotextile filter bags along coastlines, riverbanks and slopes effectively helps prevent landslides and floods, because the stacked geobags hold back waves and water flow so the damage is limited.

3.     Temporary or Permanent Dikes

Geobags are also effective as temporary or permanent dikes because they can hold back incoming water and waves. Besides being cheaper than concrete construction, geobags are considered safer and more environmentally friendly.

Types of Geotextile Bag

As explained above, a geobag is a type of sack made of geotextile. Geotextile itself comes in two types: woven and non-woven. Here are the types of geobag, classified by material:

●        Woven Geotextile Bag

A woven geotextile bag is a geobag made of woven geotextile. This geosynthetic product uses polyester and polypropylene, which are known for their strong resistance to UV rays, microorganisms and chemical compounds.

The weave of woven geotextile produces fibers with fairly high tensile strength, so the bag is strong and durable for long-term use. Woven geobags are usually black.

●        Non-Woven Geotextile Bag

Non-woven geobags use geotextile that is not woven. They are made of polyester and polypropylene fibers joined by bonding, needle punching and mechanical interlocking. They are white, strong, flexible and long-lasting.

Woven or non-woven geotextile bags can be chosen according to your needs, but both are of good quality and durable. If you need top-quality geobags, you can order them at https://petrane.co.id/.
