2. What Is BPM HDPE Geomembrana?
HDPE geomembrana is a specific type that refers to high-density polyethylene geomembranas. BPM HDPE Geomembrana is a type of geotextile anti-seepage material that utilizes a plastic film as its base material. It is compounded with non-woven fabrics to enhance its anti-seepage performance. The effectiveness of the geomembrana in preventing seepage primarily relies on the anti-seepage properties of the plastic film.
Geomembrana is commonly made with plastic films including high-density polyethylene(HDPE), polyvinyl chloride (PVC), polyethylene (PE), ethylene/vinyl acetate copolymer (EVA), and ethylene vinyl acetate modified asphalt copolymer (ECB).
HDPE geomembrana is a new polymer material with a thickness typically ranging from 0.5mm to 3mm. BPM manufactures smooth geomembranas in commonly used thicknesses such as 0.5mm, 0.75mm, 1.0mm, 1.5mm, 2.0mm, and 3.0mm (20, 30, 40, 60, 80, and 120 mils).
HDPE geomembranas are widely recognized for their excellent anti-aging and waterproof properties. They are extensively employed in various industries including water conservancy, petrochemical, agriculture, and aquaculture. These geomembranas exhibit durability, resistance to aging, and high impermeability, making them suitable for applications where reliable containment and seepage prevention are essential.
Geomembranas, including HDPE geomembrana, provide crucial protection for the environment and human health. They effectively prevent soil and groundwater contamination, ensuring the integrity of containment systems. Additionally, they act as a barrier against harmful vapors, further enhancing environmental safety.
The versatility, durability, and resistance to chemicals and temperature changes make HDPE geomembrana an ideal choice for a wide range of applications. Whether in water conservation projects, petrochemical facilities, agricultural settings, or aquaculture operations, HDPE geomembranas play a vital role in providing effective anti-seepage solutions and safeguarding the surrounding environment.
3. What Are Types of Geomembrana?
Several types of geomembranas can be used depending on the matrix resin used. The most commonly used geomembranas are listed below.
3.1 PVC Geomembrana
PVC (polyvinyl chloride) geomembrana is a thermoplastic waterproofing material made of vinyl, plasticizers and stabilizers.
When dichloroethane cracks into dichlorides, the products polymerize to create the polyvinyl chloride resin used in PVC geomembranas.
PVC geomembranas are tear, abrasion and puncture resistant and are suitable for use in the construction of canals, landfills, soil remediation, wastewater lagoon liners and storage tank liners. The material is also ideal for maintaining drinking water and preventing contaminants from entering water sources.
3.2 TRP Geomembrana
TRP (reinforced polyethylene) geomembranas use polyethylene fabrics for long-term waterproofing and industrial waste applications.
TRP geomembranas are ideal for soil remediation, landfills, canals, temporary reservoir linings, agricultural and municipal applications due to their low temperature range, chemical resistance and UV stability.
3.3 HDPE Geomembrana
High-density polyethylene (HDPE) offers strong UV/temperature resistance, low material cost, durability and high chemical resistance.
It is the most commonly used geomembrana because it has a higher thickness that other geomembranas do not have. HDPE is the first choice for pond and canal lining projects, landfills and reservoir covers. HDPE can be used to store drinking water due to its chemical resistance.
3.4 LLDPE Geomembrana
LLDPE (Linear Low Density Polyethylene) geomembrana is made of pure polyethylene resin, which is strong, durable, UV and low temperature resistant.
Engineers and installers who need an impermeable geomembrana often choose LLDPE because of its greater flexibility compared to HDPE.
They are used in industrial applications such as animal and environmental waste containers and liquid storage tanks.
3.5 RPP Geomembrana
RPP (reinforced polypropylene) geomembranas are polyester-reinforced liners made from UV-stabilized polypropylene copolymers that provide material stability, chemical resistance, and flexibility.
Its strength and durability can be traced back to the nylon scrim support. RPP geomembranas are ideal for long-term waterproofing and industrial waste applications.
RPP is ideal for municipal applications, evaporation pond liners, aquaculture and horticulture, and tailings.
3.6 EPDM Geomembrana
EPDM (ethylene propylene diene monomer) geomembrana has a rubber-like texture that gives it durability, UV stability, strength, and flexibility.
They are ideal for extreme weather conditions and puncture resistant. EPDM geomembranas are easy to install and are commonly used as surface barriers in dams, liners, mulches, backyard landscaping and other irrigation sites.

5. How To Install HDPE Geomembane Liner?
5.1 Construction Method
Do not drag or pull the geomembrana during transportation to avoid being stabbed by sharp objects.
It should be extended from the bottom to the high position. Do not pull it too tightly. There should be a margin of 1.50% to prepare for local sinking and stretching. Taking into account the actual conditions of this project, the slopes are laid in order from top to bottom;
The longitudinal joints of two adjacent panels should not be on a horizontal line, but should be staggered by more than 1m from each other;
The longitudinal joint should be more than 1.50m away from the dam foot and bent foot, and should be located on a flat surface;
Go to the slope first and then to the bottom;
When laying on the slope, the direction of the film expansion should be basically parallel to the maximum slope line.
5.2 How To Lay HDPE Geomembane Liner?
Before laying the geomembrane, the corresponding acceptance certificate of the civil engineering project should be obtained.
Before cutting the HDPE geomembrane, its relevant dimensions should be accurately measured and then cut according to the actual size. Generally, it is not suitable to cut according to the size shown in the figure. The pieces should be numbered one by one and recorded in detail on a special form.
When laying geomembrana, we should strive to minimize welds and save raw materials as much as possible while ensuring quality. It is also easy to ensure quality.
The overlap width of the seams between membranes is generally not less than 10cm. Usually, the welding seam arrangement direction is parallel to the maximum slope, that is, arranged along the slope direction.
Usually in corners and deformed areas, the length of joints should be shortened as much as possible. Except for special requirements, on slopes with a slope greater than 1:6, there should be no welds within 1.5 meters of the top slope or stress concentration area.
When laying the geomembrana, artificial wrinkles should be avoided. When the temperature is low, it should be tightened and laid as flat as possible.
After the geomembrana is laid, walking on the membrane surface, moving tools, etc. should be minimized. Objects that can cause harm to the anti-seepage membrane should not be placed on the membrane or carried while walking on the membrane to avoid damaging the membrane. causing accidental injury.
6. Relevant Regulations For Geomembrana
Quality standards are crucial when purchasing geomembrana liner for your project. HDPE geomembrana’s physical properties such as tensile strength and tear resistance are calculated based on test methods specified by ASTM and GSI.
