The geotextiles used today are multi-layered, but one thing we should know is that it is the inner membrane that determines the core properties of a geotextile. There are many kinds of geotextiles, and different geotextiles have their own production techniques. Fundamentally, geotextiles have different properties because of different materials.

　　 According to the strength between layers of geotextile, we can get a ranking of geotextile materials, but this does not mean that the first is the best, and the ones below are not durable. Each geotextile has its own range of use, and this geotextile is the most suitable in a specific range of use.

Geotextiles that are not suitable for market demand will not be produced. It is for this reason that most of the geotextiles we can see now exist in their own engineering use places.

　　 The development of modern organic chemistry has made many materials become organic materials, as is the inner membrane of our current geotextiles. This material is not a material but a collective name for a collection of materials or artificial materials. This material can be customized according to our needs. In the occasions where the strength is very high, we can produce a material with a very large force between molecules. The strength of this material is very high, and so are others.

The material used in the inner layer determines the overall properties of the engineering geotextile, which determines the place where the geotextile is used, but other outer films are also important, which determine the stability of the geotextile when used. It can be seen that even simple geotextiles contain a lot of mystery.
