Is geotextile waterproof material?
Release time:
2025-05-13
Comprehensive authoritative sources (such as Baidu Encyclopedia [1) and engineering application analysis, the waterproof function depends on the material structure, and only specific types of composite geotextiles have waterproof properties.
Ordinary geotextiles do not have waterproof functions, but composite waterproof geotextiles (such as anti-seepage geotextiles) can achieve waterproofing effects by combining plastic films with non-woven fabrics.
Detailed analysis
Properties of ordinary geotextiles
Ordinary geotextiles (such as needle-punched non-woven fabrics) are made of synthetic fibers (nylon, polyester, polypropylene, etc.), and have water permeability, anti-filtration isolation functions. They are mainly used in reinforcement, drainage and other engineering scenarios, but they are not waterproof in themselves.
Structure and mechanism of waterproof geotextile
Composite Material: Waterproof geotextiles (such as composite geomembrane) use the water-permeability of the film to achieve anti-seepage by combining plastic films (PVC, PE) with non-woven fabrics.
Core performance: It has both tensile strength (provided by non-woven fabric) and anti-seepage capability (provided by plastic film), and is suitable for waterproofing projects such as reservoirs and dams.
Apply distinction
Non-waterproof scenarios: Ordinary geotextiles are used for roadbed reinforcement, soil filtration, etc.
Waterproof Scenario: Waterproof geotextiles are used in water conservancy projects, landfills and anti-seepage.
Purchase precautions
The product name prefix (such as "waterproof" or "seepage-proof") must be clarified to avoid confusing ordinary geotextiles with waterproof geotextiles.
Authoritative conclusion
Comprehensive authoritative sources (such as Baidu Encyclopedia [1) and engineering application analysis, the waterproof function depends on the material structure, and only specific types of composite geotextiles have waterproof properties.

Is the geotextile room a reverse filter geotextile?
Functional differences: Geo-frames are mainly used for soil stability and foundation reinforcement, while reverse filter geotextiles are mainly used for filtration and anti-seepage.

What is a geotechnical room for
Through its three-dimensional constraint mechanism, geotextile chambers have become a key technology for solving soil stability problems in modern infrastructure. They are widely used in roads, slopes, environmental protection and other fields, and have both engineering efficiency and ecological benefits.

The difference between geogrid and geogrid
Geo-rooms are more suitable for scenarios that require three-dimensional reinforcement and complex terrain processing (such as soft foundations, steep slopes), while geogrids are more suitable for conventional projects with high demand for plane tensile resistance (such as roadbed cracking). Project selection needs to be combined with geological conditions, load requirements and cost budget.

Is the geogrid paved vertically or horizontally
The main mechanical directions of the soil are mostly horizontal, and horizontal laying can maximize the reinforcement effect of the grid.
