Bentonite waterproof blanket (GLC) is a common building waterproofing material with excellent waterproof performance. It has been widely used in the fields of building waterproofing, ecological environment engineering, water conservancy and hydropower, chemical industry, underground engineering, tunnel engineering, dams and other fields.

Non-woven fabric and non-woven geotextile are two different materials. They have some differences in materials, uses and characteristics.1. Material: Non-woven fabric is usually a kind of fabric composed of fibers combined by chemical or physical methods. Common materials include polyester, polypropylene, polyethylene, etc. Non-woven geotextile is an inorganic textile specifically used in geotechnical engineering and is usually made of synthetic fibers such as polypropylene or polyester.2.

PP geotextile and PET geotextile are common geotextile materials, they have the following differences:Material composition: PP geotextile is made of polypropylene (PP) fibers and PET geotextile is made of polyester (PET) fibers. Due to the different materials, their performance and characteristics will also be different.Physical properties: PP geotextile generally has higher tensile and rupture strength, while PET geotextile has higher strength and stiffness.

HDPE geomembrane is also called high-density polyethylene film, HDPE geomembrane, HDPE anti-seepage membrane. HDPE film is a plastic roll made of HDPE. HDPEis a kind of high crystallinity. 1. HDPE geomembrane is a flexible Waterproof material with high anti-seepage coefficient (1×10-17 cm/s);2. HDPE geomembrane has good heat resistance and cold resistance, and its operating environment temperature is high temperature 110℃ and low temperature -70℃;3.

Filament geotextiles and traditional earthmoving materials each have their own advantages in earthmoving applications. Filament geotextile is a non-woven material  made of polymer synthetic materials with high tensile strength, anti-penetration and anti-aging properties.

Short fiber geotextile is a geomaterial made of high-strength short fibers with excellent environmental performance. The following are the main advantages of short-filament geotextile in environmental protection:1. Degradability: Short fiber geotextile is made of degradable materials, which can naturally degrade within a certain period of time and will not cause long-term pollution to the environment. The degradability of short fiber geotextiles can not only reduce soil and groundwater pollution, but also effectively reduce the amount of garbage produced.2.

Filament geotextile is a kind of geosynthetic material that can be used to prevent soil erosion. It has the advantages of water permeability, air permeability, filterability and tear resistance. How to correctly choose and use filament geotextile can effectively reduce soil erosion and protect land resources. Below are suggestions for the selection and use of filament geotextiles.（1）Correctly choose the specifications and types of filament geotextile1.

Geomaterials are a special class of materials used in the field of civil engineering to improve soil properties, increase the stability and bearing capacity of the soil body, as well as to provide seepage control, erosion control, protection and other functions. Common geomaterials include geosynthetics, geomembranes, geogrids, geotextiles and geotubes.Here mainly introduces a few of the most commonly used geomaterials:1. Geotextile: Geotextile is mainly made of polyester fiber or polypropylene fiber, which has good impermeability, protection and enhancement ability.

Short fiber geotextile is a geotextile made of synthetic materials such as polyester or polypropylene, and its surface is covered with short filament-like fibers. This geotechnical material is often used to prevent soil erosion and collapse, effectively protect land resources, and maintain the ecological environment.Soil erosion and collapse are issues that seriously affect land use and the ecological environment.

Composite geomembrane is a composite material composed of different materials. It has certain permeability and anti-seepage properties and is widely used in soilengineering and environmental engineering. As a soil pollution control material, composite geomembrane has high adsorption, isolation and stability, and caneffectively reduce soil pollution.First of all, composite geomembrane has strong adsorption properties. Composite geomembrane materials often contain active ingredients with good adsorptionproperties, such as activated carbon that adsorbs heavy metals.
