Product Description

Introduction

Composite geomembrane is a geosynthetic fabric composed of more than one layers of materials, commonly consisting of a cloth layer, reinforcement layer, anti-seepage layer, and defensive layer. This composite shape endows geomembranes with suitable waterproof, anti-seepage, tensile strength, and puncture resistance, making them appropriate for waterproofing, anti-seepage, and reinforcement purposes in quite a number engineering fields.

Working Drawing

Fabric layer: used to decorate the mechanical homes and sturdiness of geotextiles, typically made of high-strength artificial fiber substances such as polyester and polyamide.

Reinforcement layer: To make bigger the electricity and balance of geotextiles, reinforcement substances such as glass fiber and polyester fiber are generally used to decorate their tensile, tear resistance, and compressive properties.

Impermeable layer: As a key phase of geomembrane, it has appropriate water resistant and impermeable properties, normally the usage of polymer substances such as polyethylene and polypropylene to successfully forestall water and chemical elements from penetrating.

Protective layer: used to defend geosynthetic membranes from exterior damage, UV light, and chemical erosion, usually the usage of polyethylene movie or different protecting substances as the floor masking layer.

Composite geomembranes are extensively used in fields such as water conservancy engineering, civil engineering, environmental engineering, and landscaping engineering, often for waterproofing treatment, basis reinforcement, anti-seepage engineering, landfill sites, chemical plant waste treatment, etc. Its benefits consist of corrosion resistance, getting old resistance, handy construction, etc. It is an vital geotechnical material.
