Product Description

Introduction

Composite geomembrane is a geosynthetic material composed of multiple layers of materials, typically consisting of a fabric layer, reinforcement layer, anti-seepage layer, and protective layer. This composite structure endows geomembranes with good waterproof, anti-seepage, tensile strength, and puncture resistance, making them suitable for waterproofing, anti-seepage, and reinforcement applications in various engineering fields.

Working Drawing

Fabric layer: used to enhance the mechanical properties and durability of geotextiles, usually made of high-strength synthetic fiber materials such as polyester and polyamide.

Reinforcement layer: To increase the strength and stability of geotextiles, reinforcement materials such as glass fiber and polyester fiber are usually used to enhance their tensile, tear resistance, and compressive properties.

Impermeable layer: As a key part of geomembrane, it has good waterproof and impermeable properties, usually using polymer materials such as polyethylene and polypropylene to effectively prevent water and chemical substances from penetrating.

Protective layer: used to protect geosynthetic membranes from external damage, UV light, and chemical erosion, typically using polyethylene film or other protective materials as the surface covering layer.

Composite geomembranes are widely used in fields such as water conservancy engineering, civil engineering, environmental engineering, and landscaping engineering, mainly for waterproofing treatment, foundation reinforcement, anti-seepage engineering, landfill sites, chemical plant waste treatment, etc. Its advantages include corrosion resistance, aging resistance, easy construction, etc. It is an important geotechnical material.
