Description

Introduction

Non woven geotextile is a type of geotextile, typically made from synthetic fibers such as polypropylene or polyester through thermal bonding or needle punching processes. It has multiple uses in the field of civil engineering, including but not limited to the following aspects

Applications

Soil filtration: Non woven geotextiles can serve as soil filtration layers, effectively preventing the flow of soil particles and solid particles, and protecting the foundation soil and earthwork.

Soil isolation: used to isolate soil layers with different particle sizes, prevent soil coagulation and mutual infiltration, and improve the stability of engineering structures.

Soil drainage: As a drainage layer, it can accelerate the discharge of surface and underground water, prevent soil liquefaction and structural deformation caused by wetting.

Working Drawing

Soil slope protection: used for slope protection and protection, to prevent soil erosion, slope collapse, and maintain terrain stability.

Road paving: As an isolation and reinforcement material for the road base and roadbed, it improves the bearing capacity and durability of the road.

Greening project: used for vegetation coverage, soil consolidation, plant cultivation and other greening projects to promote plant growth and soil protection.

Water conservancy engineering: applied in water conservancy projects such as dams, reservoirs, and canals to protect the structure and soil stability of the project.

Non woven geotextiles have good permeability, breathability, and filtration performance, which can effectively improve the engineering performance of soil, enhance the stability and durability of soil, and are widely used in various civil engineering projects.
