How to choose the appropriate thickness and specification of geotextile?

Geotextile is a geotechnical material used for soil reinforcement and protection. The selection of its thickness and specifications directly affects its use effect and economy. 

Therefore, the correct selection of suitable thickness and specifications is very important for project quality and cost control.

First of all, choosing the appropriate thickness of geotextile requires considering the following factors:

1. Load bearing: The thickness of the geotextile is related to the load it bears. Generally speaking, in places that bear larger loads, choosing a thicker geotextile can provide

better strength and stability.

2. Life expectancy requirements: The life span of geotextiles is closely related to their thickness. Generally speaking, thicker geotextiles have a relatively longer life, but they

also need to be considered comprehensively based on the actual situation.

3. Soil properties: The thickness selection of geotextile also needs to consider the properties of the soil, such as soil stickiness, moisture content, etc. If the soil is loose or

has a lot of water, you need to choose a thicker geotextile to enhance its anti-seepage and anti-skid capabilities.

Secondly, selecting appropriate geotextile specifications also requires comprehensive consideration of the following points:

1. Difficulty of installation: The specification selection of geotextile needs to consider its installation difficulty. For more complex construction sites, smaller size geotextiles can

be chosen to facilitate construction placement and connection.

2. Strength requirements: The specification selection of geotextile also needs to be determined according to the strength requirements of the project. For situations where

greater loads are required, higher strength geotextiles need to be selected.

3. Economics: What needs to be considered is the economics of geotextile. The cost of geotextiles with larger sizes is relatively high, so it is necessary to choose the

appropriate specifications based on the project budget and affordability.

To sum up, choosing the appropriate geotextile thickness and specification requires taking into account factors such as load bearing, life requirements, soil properties,

installation difficulty, strength requirements and economy. In actual projects, appropriate thickness and specifications can be determined through communication with

geotechnical experts and field surveys to ensure maximum project quality and economic benefits.
