High-Performance PP Non-Woven Geotextile: The Ultimate Separation, Filtration, and Protection Solution for Roadway Construction

Product Description:
Our high-performance non-woven PP Geotextile is engineered from 100% polypropylene filaments, utilizing a advanced needle-punching process to create a durable, permeable fabric. This structure provides exceptional tensile strength and elongation, making it highly resistant to punctures and tears during installation and service. Its primary function is to act as a reliable separator between distinct soil layers, such as soft subgrade and aggregate base, preventing their intermixing. Simultaneously, its uniform pore structure allows for efficient water flow (filtration), preventing pore pressure build-up. The fabric also serves as a protective cushion, shielding delicate geomembranes from sharp objects in the subsoil.

Application Scenarios:

• Separation in Unpaved Roads: Prevents fine-grained subsoil from mixing with the coarse aggregate base, maintaining the structural integrity and load-bearing capacity of the road.

• Filtration in Drainage Ditches: Wrapped around drainage pipes or aggregate, it allows water to enter while preventing soil erosion and pipe clogging.

• Protection for Landfill Liners: Installed as a cushioning layer above and below geomembranes in landfill sites to protect them from puncture.

Engineering Project Applications:
This geotextile is critical in the construction of highway embankments, airport runways, and port container yards. In these projects, it is placed directly on the prepared subgrade before the aggregate base is laid. This application ensures long-term separation and stability, significantly reducing maintenance costs and extending the project's service life by preventing structural failure due to soil contamination.
