Composite Geomembrane The Ideal Material for Anti-Seepage in Environmental Protection and Water Conservancy Projects

Product Introduction

Composite geomembrane is a composite material that combines geotextile and plastic film. It is widely used in many fields, especially in projects that require efficient anti-seepage. The following is a detailed introduction to composite geomembrane:

Definition and structure of composite geomembrane
Composite geomembrane is a composite structure formed by attaching geotextile on one or both sides of a plastic film. It has various forms, including one cloth and one membrane, two cloths and one membrane, etc. Geotextile serves as a protective layer to effectively protect the anti-seepage layer from damage, while reducing ultraviolet radiation and increasing anti-aging performance2.

Main types
One cloth and one membrane: suitable for occasions that require additional protection.
Two cloths and one membrane: provide double protection and enhance the overall structural strength.

Application fields of composite geomembrane
Composite geomembrane has a wide range of applications in many fields due to its excellent anti-seepage performance:

Environmental protection
Used in environmental protection fields such as wastewater treatment, sewage treatment, landfills and hazardous waste landfills, effectively preventing leakage and pollution.
Water conservancy projects
Applicable to water conservancy projects such as dams, reservoirs, tunnels, bridges, and seawalls, which can effectively prevent leakage and pollution.
Agricultural planting
Can be used in agricultural construction such as orchard drainage, channel covering, anti-film covering, and pond dam covering, with good anti-seepage effect.
Road construction
Used in road construction fields such as tunnels, roadbeds, bridges, and culverts, providing a reliable solution for road waterproofing.

Construction methods and precautions

Construction methods
The use must be buried, and the covering thickness should not be less than 30cm. -The renovation anti-seepage system should consist of a cushion layer, an anti-seepage layer, a transition layer, and a protective layer.
The soil should be solid to avoid uneven subsidence and cracks.
When laying, do not pull the geomembrane too tight, and it is better to have the two ends buried in the soil in a corrugated shape.

Precautions
During construction, stones and heavy objects should be avoided from hitting the anti-seepage composite geomembrane directly.
It is best to lay the membrane and cover the protective layer while constructing.

Material selection and characteristics
The materials of composite geomembranes include any possible material combination, such as ceramic membranes on metal oxides or aromatic polyamide films on polysulfone microporous membranes. The flat membranes or roll membranes must be reinforced with nonwovens to support the microstructure.

Main characteristics
High strength
Good elongation performance
Acid and alkali resistance, corrosion resistance
Aging resistance
Good anti-seepage performance

Market supply
There are many companies specializing in the production and sale of composite geomembranes in the market, such as Shandong Hengyang New Materials Co., Ltd. and Shandong Lingxiang New Materials Co., Ltd. These companies provide products of various specifications and models to meet the needs of different customers.

In summary, composite geomembranes, as an important geosynthetics, play an important role in many fields. Understanding its definition, structure, application field, construction method and material characteristics will help to better select and use this material and ensure the quality and effect of the project.
