PVC Geomembrane
PVC (Polyvinyl Chloride) geomembranes is a thermoplastic waterproofing material made with vinyl, plasticizers, and stabilizers.
TRP Geomembrane
A TRP (Reinforced Polyethylene) geomembrane uses polyethylene fabric for long-term water containment and industrial waste applications.
HDPE Geomembrane
High-Density Polyethylene (HDPE) is characterized by strong UV/temperature resistance, inexpensive material cost, durability, and high resistance to chemicals.
LLDPE Geomembrane
LLDPE (Linear Low-Density Polyethylene) geomembrane is made with virgin polyethylene resins which make it strong, durable, and resistant to UV & low temperature.
RPP Geomembrane
RPP (Reinforced Polypropylene) geomembranes are polyester-reinforced liners made from a UV-stabilized polypropylene copolymer that gives the material stability, chemical resistance, and flexibility.

Raw Material Selection
The first step in geomembrane manufacturing is the selection of high-quality raw materials. The most commonly used materials are high-density polyethylene (HDPE) and polyvinyl chloride (PVC). These materials are chosen for their excellent properties, such as chemical resistance, puncture resistance, and long-term durability.
Extrusion
Once the raw materials have been selected, they are extruded through a heated die to form a long, flat sheet. The extrusion process involves melting the plastic and forcing it through a narrow opening, creating a continuous sheet of geomembrane.
Calendering
After extrusion, the geomembrane sheet is passed through a series of calendering rollers. These rollers flatten and smooth the sheet, ensuring a uniform thickness and texture.
Inspection and Testing
Quality control is a critical step in geomembrane manufacturing. The finished sheets are inspected for defects, such as wrinkles, holes, or uneven thickness. They are also subjected to various tests to ensure that they meet the required specifications for strength, chemical resistance, and impermeability.
Finishing and Packaging
The final steps in the manufacturing process involve finishing and packaging. The geomembrane sheets may be cut to specific sizes or lengths, and they are then packaged for shipment.
Water Conservation in Agriculture
In the realm of agriculture, geomembrane sheets play a pivotal role in water conservation. They act as efficient barriers, preventing water seepage and ensuring optimal irrigation practices.
Landfill Liners for Waste Management
The application of geomembrane sheets as landfill liners is transforming waste management. These liners provide a secure barrier, preventing harmful substances from infiltrating the soil and groundwater.
Geomembranes in Mining Operations
Mining operations benefit from the use of geomembrane sheet in tailings management. This not only enhances operational safety but also minimizes environmental impact.
Aquaculture Applications
Geomembrane sheet find utility in fish farming, creating controlled environments for optimal aquatic life.

Packaging & Shipping
Pumps are packed in reinforced wooden crates with foam padding to prevent ceramic damage.
Internal components are separated and labeled clearly for easy reassembly.
