What is HDPE waterproof membrane? Features and applications

You know, for many people, the HDPE waterproof membrane is no longer a strange product because of its popular use. However, knowing what HDPE waterproof membrane is with the features and application of this membrane, surely not everyone knows exactly. So in the article below we will explain in detail the content related to this waterproof membrane called HDPE.

1. What is the concept of HDPE film?

In fact, waterproof HDPE film is also referred to as HDPE film. This is the type of membrane produced from high-content Polyethylene particles by extrusion method or by crude method.

2. Features of the HDPE waterproof membrane

The HDPE film line possesses many special features that not all products can be replaced. We can take a look at some of the most characteristic features:
- Thanks to the extremely small permeability coefficient, the product is considered absolute waterproof. So it is used for many projects that need water storage or waterproofing.
This HDPE waterproof membrane remains inert to all solvents. So it is often used to store many harmful substances, for waterproofing or in brackish water environments ...
- Possesses elastic function and good physical resistance. Specifically, the HDPE film has elasticity up to 700% and high tensile and tear resistance.
- HDPE film is also resistant to UV rays, ultraviolet rays, sunlight even when the light shines continuously.

3. What is the application of the HDPE waterproof membrane?

With many unique features, the waterproof HDPE membrane is widely used in many different construction projects:

a. Application in domestic landfill, industrial landfill

For industrial landfills, wholesale yards, domestic landfills ..., using HDPE waterproof membranes with a thickness of 1.5 to 2.5mm will help extremely high waterproofing.

b. Application in industrial waste treatment

As mentioned, because the HDPE film possesses an extremely high UV and UV resistance additive, it will be completely undamaged if exposed to the sun. So the product is used to cover the face of the landfill to prevent bad odors and prevent hazards from the landfill. Usually people use HDPE waterproof membrane with a thickness of 1.0mm to 0.75mm to cover.
In addition, the HDPE membrane below the landfill uses 1.0mm to 1.5mm for the purpose of preventing leachate from seeping into the soil and affecting the surrounding groundwater and lakes.

c. Application in livestock farm

Waterproofing HDPE film on these farms will be used with a thickness of about 0.5mm. It will help with antibiotic resistance because in the pond wastewater the farm is continuously affected by microorganisms as well as livestock waste. For the bottom liner, 0.5mm can be used as it is not bearing.

d. Application in manufacturing plants

Industrial waste in the factories that manufacture it will consist of heavy metals and extremely chemically corrosive. Therefore, if discharged into the environment directly, it will be absorbed into the groundwater, affecting the water source and human health.
Therefore, using waterproof HDPE membrane as a sedimentation tank, wastewater treatment tank will prevent wastewater from seeping out more effectively.

e. Application in the aquaculture industry

The HDPE film is used in the aquaculture industry to create a barrier between the water in the aquarium and the outside environment. It will prevent water from seeping into the aquarium, helping to stabilize the pH and stabilize the salt concentration in the water, preventing pathogens from entering the tank high.
In addition, the HDPE waterproof membrane with high durability, low cost, easy construction, cleaning will help bring the best performance in this industry.

f. Application in agriculture

HDPE films are also used in agriculture as biogas tunnels, irrigation reservoirs or water ditches:
- Biogas tunnel: Should choose 1.5mm thick film covering the face and lining about 0.5mm to 0.75mm thick.
- Irrigation water reservoir: Should choose 0.5mm or 0.75mm thick HDPE waterproof membrane with a size of 4m to 8m depending on demand.
- Drainage ditch: It is necessary to choose membranes from 0.5mm or 0.3mm depending on the terrain or project.

g. Application in a number of other professions

With waterproof HDPE membrane, it is also used in mining, underground tunneling or used in sugarcane factories, landscape lakes ...
So, together we have to learn full information regarding what HDPE waterproof membrane is and its features and applications. Any needs related to the purchase of HDPE film or advice on how to use it, please contact Nam Phat Plastic for more advice!
