What is geomembrane Categories?
Geomembranes serve as impermeable barriers in geotechnical projects, working alongside soil and structural elements. While multiple variants exist—including PVC, EPDM, and LLDPE—HDPE geomembranes remain the most widely specified for industrial applications due to their superior durability.
BPM produces three primary geomembrane types:
-
Smooth geomembranes – Flat surfaces ideal for standard containment
-
Textured HDPE geomembranes – Enhanced surface friction for sloped installations
-
Composite geomembranes – Multi-layer systems combining filtration and barrier properties
Each type addresses specific project needs, from landfill liners to aquaculture ponds. Engineers select materials based on chemical exposure, slope stability, and longevity requirements.
1. Smooth geomembrane.
This kind of geomembrane is typically made of finest quality high density polyethylene (HDPE) with specially formulated, virgin polyethylene resin, combined with specified quantity carbon black, antioxidant, anti-aging agent and UV resistance components. It can be used for canal, aquaculture, irrigation ponds and remediation liners, other liner applications include landfills, waste water treatment lagoons, oil and gas exploration, power plants, etc al. BPM smooth geomembrane HDPE linere is engineered and fabricated by the state of the art automatic geomembrane production lines and advanced three layered pressing technology in accordance with GRI GM13 standard.
2.Textured HDPE geomembrane.
In general, HPDE geomembranes consist of 96–97.5% of polyethylene resin, 2–3% of carbon black and 0.5–1.0% of other additives such as antioxidants and stabilizers. Polyethylene is a high molecular polymer, non-toxic, odorless and odorless white particles, its melting point is about 110 °C -130 °C, its relative density 0.918-0.965. HDPE geomembrane is specially designed and fabricated for many applications due to its advanced stabilization, excellent interface friction coefficient and inherent flexibility. BPM HDPE geomembranes have been widely in backfilled liner, retaining backfill on steep side, heap leach pads, landfill protection applications such as dam, reservoirs, sewage pools, swimming pools, buildings, underground buildings, garbage dumps and mining projects. HDPE geomembrane designed and fabricated with either single-sided or double-sided textured surface is called Textured HDPE Geomembrane.
3. Composite geomembrane liner.
Composite geomembrane liner is made by heat-bonding nonwoven or woven geotextile to HDPE geomembrane by calendaring processing technology. BPM composite geomembrane liner provides the advantages of both geomembrane and geotextile, which is made of specially formulated HDPE resin combined with specified quantity carbon black, anti-aging agent and UV resistance components. The geotextile layer increases essential tensile strength and the geomembranes provides excellent impermeable, leak and moisture proof. Compared with traditional concrete, asphalt and compacted clay, composite geomembrane liner has proven to be far more cost effective, environmentally safe, excellent durable, chemically resistant, fast deployment and easy transportation. Composite geomembraneliner is mainly used in water dams, artificial lakes, airports, construction, environmental protection, water containment and other projects.
The selection of a geomembrane liner depends upon the application in which it will be used.
What is geomembrane functions?
Geomembranes deliver four key engineering functions in construction projects:
-
Separation – Prevents mixing of dissimilar materials (soil/sand, soil/concrete) by creating physical barriers based on particle size and density differences.
-
Drainage – Forms efficient flow channels within soil structures to remove excess liquids/gases, maintaining optimal moisture levels.
-
Reinforcement – Boosts soil tensile strength through HDPE liners, reducing deformation risks while enhancing structural stability.
-
Protection – Distributes concentrated stresses from water flow or external loads, preventing soil erosion and structural damage.
These combined capabilities make geomembranes versatile solutions for civil and environmental engineering challenges.
What is geomembrane applications?
BPM manufactures premium geomembranes using high-grade polyethylene enhanced with carbon black, antioxidants, and UV stabilizers. These engineered membranes deliver four core functions: separation, drainage, reinforcement, and protection.
The material’s multifunctional properties make it ideal for diverse applications across three key sectors:
-
Transportation: Roadbeds, airfield foundations, railroad embankments
-
Environmental: Landfill liners, reservoir seals, coastal protection
-
Geotechnical: Retaining walls, canal linings, dam reinforcements
Each application leverages the geomembrane’s durability and adaptability to address specific engineering challenges while ensuring long-term performance.
