Geomembrane uses plastic film as the anti-seepage base material. It has excellent corrosion resistance and chemical resistance, and can work stably for a long time in various harsh environments. Secondly, it is easy to construct, can adapt to the requirements of various terrains and landforms, has a long service life and low maintenance cost. In addition, the anti-seepage performance of geomembrane is good, which can effectively prevent soil erosion, pollutant leakage and other problems, and it also plays an important role in environmental protection and ecological construction.

Geotextiles have various excellent properties: 1. Good isolation performance: It can effectively separate different soil layers and rock layers, preventing them from mixing and interfering with each other. 2. Filtering function: allowing water to pass through while effectively intercepting soil particles and other impurities. 3. Drainage function: Accelerate the discharge of water and improve the stability of the project.

Geogrid has the following prominent features: 1. High tensile strength: It can effectively resist tensile stress and enhance the stability of soil. 2. Grid structure: Unique grid design that can fully engage with the soil, improving the overall integrity of the soil. 3. Strong corrosion resistance: It can maintain good performance under harsh environmental conditions and is not easily corroded by chemical substances.

Geogrid is a three-dimensional mesh structure formed by high-strength welding of polymer sheets. 1. Powerful lateral confinement effect: It can effectively constrain the lateral displacement of the soil and improve its stability. 2. Good erosion resistance: It can slow down the erosion of soil by water flow or wind. 3. High bearing capacity: increases the compressive strength of the soil to withstand larger loads.

Geotextile bags have the following characteristics: Good flexibility: can adapt to different terrains and construction conditions. Strong permeability: allows water to pass freely while intercepting soil particles, etc. Corrosion resistance: can maintain stable performance for a long time in harsh environments.

HDPE geotube is a geotube made of high-density polyethylene (HDPE) material. Its features include: 1. High chemical stability: good tolerance to most chemicals and not easily corroded. 2. Strong wear resistance: able to maintain good performance in complex geological conditions and construction environments. 3. Good sealing: effectively prevents leakage of liquids or gases.

According to the production process, it can be divided into needle-punched sodium bentonite waterproof blanket, needle-punched film-coated sodium bentonite waterproof blanket and adhesive-coated sodium bentonite waterproof blanket. The needle-punched film-coated method is to compound a layer of high-density polyethylene geomembrane on the outer surface of the non-woven geotextile of the needle-punched sodium bentonite waterproof blanket; the adhesive method uses an adhesive to bond bentonite particles to a high-density polyethylene board for compression production.

Advantages of plastic film: 1. Agriculture: used for greenhouse covering, ground film, etc., to keep warm, keep moist, and prevent insects. For example, in a vegetable greenhouse, plastic film can maintain a suitable temperature and humidity to promote vegetable growth. 2. Packaging industry: packaging food, daily necessities, industrial products, etc. For example, plastic wrap in food packaging can extend the shelf life of food. 3. Industry: used for rainproof, dustproof, isolation, etc. 4. Construction field: as part of waterproof roll material.
