Product Introduction
Basic attributes
Geotextile 700g m2 are made from polymer materials such as polypropylene and polyester, and are processed through weaving, needle punching, or hot rolling techniques. Its physical characteristics are characterized by a soft texture and excellent flexibility, which can be folded and bent freely without being easily damaged; In terms of chemical performance, it has excellent corrosion resistance, can resist the corrosion of chemical substances such as acid, alkali and salt fog, and has strong anti-aging and anti ultraviolet capabilities. Even in the harsh natural environment such as high temperature, cold, strong sunshine, it can maintain structural integrity and stable service performance for a long time.
Core functions
Anti leakage function: By forming a physical barrier through a dense fiber structure, it can effectively block the infiltration of surface water, groundwater, industrial waste liquids, and harmful gases. In water conservancy dams, artificial lakes, landfill sites and other projects, it can accurately prevent structural instability caused by water leakage, while also preventing the spread of pollutants and pollution of surrounding water and soil resources.
Protective function: With the buffering and dispersing effect of the fiber layer, external loads can be evenly transmitted to the base soil, reducing local pressure concentration. In road engineering, it can protect the roadbed from vehicle crushing and damage, and in river regulation, it can resist the erosion of embankments by water flow, thereby maintaining the long-term stability of various engineering structures.
Drainage function: Utilizing the porous structure and fiber gaps inside the material to form drainage channels, it has good permeability. In civil engineering construction, excess accumulated water caused by rainfall and groundwater infiltration can be quickly discharged from the soil, reducing the pore water pressure of the soil, avoiding problems such as soil softening and settlement caused by accumulated water, and ensuring that the engineering structure is in a dry and stable state.
Main features
Convenient construction: The product has a lightweight texture, moderate weight per roll, and does not require large lifting equipment for handling and laying. It can be operated manually. The material cutting is flexible and can be quickly adjusted according to the actual size of the project, greatly reducing material waste. Compared to traditional anti-seepage and protective materials, it can significantly shorten the construction period and reduce labor and equipment costs.
Strong durability: relying on high-quality raw materials and advanced production technology, the product has outstanding corrosion resistance and aging resistance, and can withstand the impact of chemical substances, microorganisms, ultraviolet rays, alternating cold and heat and other natural factors in the soil for a long time. Under normal usage conditions, the service life can reach several decades, effectively extending the overall service life of the project and reducing maintenance costs in the later stages.

Product Application
Water conservancy engineering field
In hydraulic engineering, geotextile is an important anti-seepage and protective material. Commonly used in projects such as dams, channels, and artificial lakes, it has excellent anti-seepage performance to prevent water leakage and ensure the stability of dam structures; At the same time, it can resist water flow erosion, protect embankments and channel slopes from erosion, and reduce soil erosion.
Road construction field
In road construction, geotextiles mainly play a protective and reinforcing role. Laying between the roadbed and the road surface, it can disperse vehicle loads, reduce roadbed settlement and deformation, and prevent problems such as cracking and collapse of the road surface; In the treatment of soft soil foundation, it can also enhance the bearing capacity of the foundation and improve the durability of the overall road structure.
Environmental engineering field
Environmental engineering is one of the key application scenarios for geotextiles. In landfills, as the core material of the anti-seepage layer, it can effectively block the infiltration of garbage leachate into the soil and groundwater, avoiding environmental pollution; In projects such as sewage treatment plants and tailings treatment, it is also used for anti-seepage and filtration to ensure the ecological safety of environmental protection engineering.
Municipal and Civil Engineering Fields
In municipal engineering, geotextiles are commonly used for underground pipeline laying, foundation pit support, and other scenarios. Laying around the pipeline can reduce the pressure of soil on the pipeline and prevent pipeline damage; During foundation pit construction, it can play a role in drainage and reinforcing slopes, ensuring construction safety. In addition, in projects such as artificial wetlands and roof greening for landscaping, drainage and protection functions can also be utilized.
Geotextiles play an irreplaceable role in various engineering fields such as water conservancy, roads, environmental protection, and municipal engineering due to their core functions of anti-seepage, protection, and drainage. Its convenient construction and strong durability not only improve the quality and stability of the project, but also reduce the construction cost and maintenance pressure in the later stage, making it an indispensable key material in modern engineering construction.
