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.

HDPE geomembrane is a kind of anti-seepage material made of high-density polyethylene material, which has good corrosion resistance, aging resistance and tensile strength. It is usually used in engineering projects for waterproofing, anti-seepage, isolation and other needs. The following is an introduction to the function and application scope of HDPE geomembrane:1.

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.

Geotextile is a kind of material used in civil engineering and land improvement. Its main functions include the following aspects:1. Geotextiles can be used to protect soil and prevent soil erosion, landslides and other geological disasters.2. Geotextiles can be used for soil filtration and drainage, helping soil drainage and maintaining soil structural stability.3. Geotextile can be used to separate soil, prevent soil layers of different particle sizes from mixing together, and maintain uniformity and stability of the soil structure.4.

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.

Non-woven geotextile is a textile material made of polypropylene, polyester and other synthetic fibers through thermal bonding or needle punching processes. It has the characteristics of high strength, waterproof, water permeable, breathable, corrosion resistance and other characteristics. It is mainly used in civil engineering, water conservancy engineering, traffic engineering and other fields, and has a variety of functions and application scopes:1.

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.

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.

Geotextile is a cloth-like material made of synthetic fibers with the following characteristics:1. Corrosion resistance: geotextile is usually made of synthetic fiber materials such as polypropylene or polyester, which has good corrosion resistance and can resist the erosion of acids, alkalis, chemicals and microorganisms to prolong its service life.2. High tensile strength: geotextile has high tensile strength and tensile properties, able to withstand greater tensile force, enhance the stability and strength of the soil body.3.
