Is Geotextile Flammable? 

This article will answer the question, is geotextile flammable? It also covers several topics about geotextile, what are the types of geotextile, its benefits, and the fire handling method caused by geotextile burn.

Is Geotextile Flammable?

No. Geotextile is not flammable, yet it is combustible. Unless it has been warmed, geotextile will not burn. Molten or otherwise overheated material can burn more slowly and produce more smoke. Stay away from the vapor and avoid breathing it in.

What is Geotextile?

Geotextiles are sheets made of synthetic materials that are thin, flexible, and porous. They are used for the stability and enhancement of soil in connection with civil engineering projects. 

In today’s world, one of the most effective methods for fortifying weak soils is the application of geotextiles. It is capable of separating, filtering, solidifying, protecting, or drying. 

Geotextile fabrics are typically constructed out of polypropylene or polyester, and they can be purchased in one of three fundamental varieties: woven, needle pressurized, or heat bonded.

What Are the Types of Geotextile?

Woven Geotextiles

Woven geotextile constructed from a woven material that is either Polypropylene (PP) or polyester. Woven geotextiles can also be referred to as Polyethylene terephthalate (PET). 

This woven geotextile possesses high tensile strength, pierce strength, and grip strength.

Non-woven Geotextiles

This geotextile is not produced through a weaving method but rather through a combination of thermal, chemical, mechanical engineering, or mechanical procedures carried out by high-tech machinery. 

Because its appearance is more similar to that of a carpet than that of woven geotextiles, many people refer to non-woven geotextiles as road carpets. The primary component of the manufacturing process is polyester fiber, while some features are made of polypropylene.

What Are the Benefits of Using Geotextile?

Woven geotextile material is typically utilized as a layer to strengthen soft subgrade. This layer is then stockpiled on top, where the woven geotextile material can uniformly distribute the load placed on it to prevent subgrade from occurring. 

Woven geotextile is also utilized as a separator and filter by placing it between the soft soil and the embankment soil. We know that geotextiles have high permeability properties, meaning that water can pass through the pores of the geotextile. 

However, in this instance, the geotextile can prevent the soil grains above it from being carried away by water. This is done to avoid the soil grains from the embankment from mixing with soft soil, which could lead to the collapse of the soil reinforcement structure.

Non-woven geotextile is not focused on strengthening soft soil; in most cases, the subgrade condition is quite good, so the non-woven type is chosen as a separating layer between the subgrade and the embankment soil. 

At first glance, its function as a separator is the same as the function of the woven type as a separator; however, this woven geotextile is not focused on strengthening soft soil.

Non-woven geotextile separator also functions as a filtration, the goal of which is to drain water down without carrying heap particles so that it does not mix with the subgrade. This is accomplished by acting as a filter.

Additionally, non-woven geotextiles are used as a wrapper for drainage pipes in the production of drainage channels. Drainage pipes typically consist of perforated or perforated pipes, and the purpose of the wrapper is to prevent soil from entering the tube while still allowing water to flow through it.

Here are some beneficial uses of geotextiles, including the following:

  • Prevents aggregate migration from the backfill into the soft subgrade, which both reduces the requirement for additional “wasted aggregate layers” and the associated costs.
  • Prevents soft subgrade from contaminating the subbase and base aggregates and distributes traffic loads more effectively through the embankment levels.
  • Decreasing the amount of work that needs to be done for preparation and cutting down on the depth of the stripping excavation.
  • Lessen the uneven settling and deformation of the structure, as well as the deformation of the system once it is finished.
  • By fortifying the embankment soil, you can increase the resistance of the embankment aggregate against localized collapse at the load location.

What Kinds of Firefighting Procedures Are Used to Put Out Burns on Geotextiles?

  • Extinguish the fire with a dry chemical extinguisher.
  • When fighting a fire, use self-contained breathing apparatus and wear protective clothing.
  • Geotextiles will burn for a short period if it is in contact with flame. However, due to the characteristics of polyester, the fire will not spread. Instead, the fabric will melt and flow away from the region where the heat is the most intense.
  • It burns slowly with a yellow smokey flame, flowery (ester) aroma, and molten material drops, releasing carbon dioxide, water, and carbon monoxide primarily when it is subjected to fire.


In the presence of fire, geotextile usage must be accompanied by a firefighting safety protocol.

Frequently Asked Question (FAQs): Is Geotextile Flammable?

Does water have the ability to permeate geotextile fabric?

Permeable geotextile membranes are made of pieces of cloth that are porous and allow water to travel through them.

What is the critical distinction between geotextile fabric and landscape fabric?

Even though landscape fabric is used as a biological barrier, geotextile materials are most commonly employed in various applications that use its filtering capabilities. 

These applications include landscape fabric, which is used as a natural barrier. As an illustration, the construction of roads typically uses these materials as permeable dividers between the various layers of materials that make up the roadbed.
