White Waterproof Geotextile Fabric for Tunnel
White waterproof filament non-woven geotextiles are essential materials used in tunnel construction for effective water management and structural integrity. These high-performance geotextiles are made from continuous filament polyester or polypropylene fibers, providing excellent waterproofing, filtration, and drainage properties. They play a crucial role in protecting tunnels from water ingress, enhancing durability, and maintaining safety standards. In this article, we will delve into the key features, specifications, applications, and benefits of using white waterproof filament non-woven geotextiles in tunnel projects.
Geotextile, also known as geotextile or geofiber, is a multi-layer fabric, usually made of materials such as polyester, polypropylene or polyethylene, and comes in two basic forms: woven (similar to sacks) and nonwoven (similar to plush). With excellent water permeability and filterability, it can protect the soil and slow down soil erosion, while also increasing the stability and carrying capacity of the soil. Often used in roads, railways, embankments and other projects as a reinforcement and protection of soil barrier, with the ability to separate, filter, strengthen, protect or drain. Nowadays, more and more geotextile derivatives such as floor, impermeable layer, floor, geotextile pipe can be beneficial in geological and environmental engineering design.
Haoyang Environmental Co., Ltd. is specialized in the production of geotextile manufacturers, filament non-woven geotextile is one of our main products, is the south to north water diversion project supplier.
