Use of impermeable geotextiles
Geotextile, also known as geotextile, is a permeable geosynthetic material made of synthetic fiber male by needling or weaving, finished in the form of cloth, generally 4-8 meters in width and 50-100 meters in length. Geotextiles are divided into broken thread geotextiles and filament geotextiles.

Polypropylene fiber applications
Polypropylene fiber is a high-strength polypropylene bundle monofilament fiber with special surface treatment technology to ensure excellent fiber dispersion in the concrete and grip with the cement body. It is generally used in fine stone concrete. Concrete fiber (concrete recommended to use 12-19mm concrete special fiber strength and good anti-cracking effect.) Tensile strength of 500mpa or more Elongation at break 15-25% Modulus of elasticity > 3800mp

Polypropylene fiber coloring process
Polypropylene fiber is one of the world's five major synthetic fibers, with the advantages of low relative density, good chemical stability, high strength, wear resistance, etc. Also, due to the abundant sources of raw materials, simple manufacturing, low prices, and therefore developed quite rapidly, in industry and daily life has been widely used. Fine denier polypropylene fiber has a unique role in water and moisture transfer

Introduction to the basic functions of geosynthetics
Drainage: Geosynthetics act as a drainage body inside the soil, which allows water to drain from the low permeability soil along its interior. For example: Geotextiles laid at the bottom of embankments can be used to dissipate pore water pressure.

Polyacrylonitrile fiber will be developed to a higher level
Polyacrylonitrile fiber is mainly characterized by its crack-blocking effect on cracks. In fact, as the low elastic modulus of polyacrylonitrile fiber is mixed in the relatively high elastic modulus of concrete
