GCL Clay Liner

BPM Geosynthetic Clay Liner (GCL) – Advanced Environmental Containment Solution

BPM's Geosynthetic Clay Liner (GCL) is a high-performance, factory-manufactured hydraulic barrier consisting of herbal sodium bentonite sandwiched between two layers of geotextiles. It is engineered to furnish extremely good sealing overall performance in a variety of containment applications, providing a dependable and low cost choice to standard compacted clay liners.

Key Product Features

1. Superior Hydraulic Barrier

Sodium bentonite swells upon hydration, forming a low-permeability seal that blocks water and leachate migration.

2. Needle-Punched Reinforcement

Mechanically bonded fibers supply brilliant inner shear energy and balance on steep slopes.

3. Self-Sealing Capability

Automatically seals minor punctures and overlaps, improving liner integrity and lowering the want for complicated welding.

4. Flexible & Conformable

Easily adapts to subgrade irregularities and differential settlements, making sure non-stop contact with the surface.

5. Environmentally Friendly

Made from natural, non-toxic bentonite—safe for use in touchy ecosystems and groundwater safety projects.

Specifications & Customization

BPM GCLs are engineered to meet a large vary of assignment demands, with customizable selections to swimsuit a range of environmental and structural requirements:

1. Roll Size:

Standard roll width is 5.8 meters, with customizable lengths and widths reachable to decrease on-site seaming and enhance set up efficiency.

2. Bentonite Mass per Unit Area:

Typically stages from 4000 to 5000 g/m², making sure strong sealing capacity. Higher bentonite content material can be precise for more suitable hydraulic overall performance or high-risk containment systems.

3. Permeability:

Ultra-low permeability ranking of less than 5 × 10⁻¹¹ m/s, making it perfect for purposes requiring stringent containment, such as hazardous waste landfills or industrial lagoons.

4. Geotextile Options:

- Woven + Nonwoven (standard): Combines electricity and filtration

- Double Nonwoven: Enhanced flexibility and sealing for irregular surfaces

- Composite Types: Available for exceptional engineering needs

5. Advanced Customization:

BPM presents GCLs tailor-made for worrying environments, including:

- High/low pH resistance for acid or alkali exposure

- Saltwater compatibility for marine or desalination applications

- Thermal stability for use in areas with multiplied temperatures or close to industrial processes

- Polymer-enhanced bentonite for most effective chemical resistance

Main Applications

BPM Geosynthetic Clay Liners (GCLs) are broadly used throughout a couple of industries for their most useful sealing overall performance and ease of installation. Key software areas include:

1. Landfills (Bottom & Capping Systems)

Used as phase of composite liner structures to stop leachate migration into the groundwater. GCLs are best for each base liners and remaining cowl systems, supplying first-rate interface friction and long-term durability.

2. Pond & Lagoon Liners

Provides an impermeable barrier for clean water storage ponds, evaporation basins, fish and shrimp farming lagoons, and wastewater containment. The flexibility and self-sealing nature of GCLs make them convenient to installation on irregular surfaces.

3. Mining Heap Leach Pads

Installed under ore thousands to comprise leachate options used in steel extraction. GCLs provide chemical resistance and face up to heavy loading, supporting to guard surrounding soil and water resources.

4. Canal and Ditch Lining

Used in irrigation and drainage structures to reduce seepage losses and make bigger water shipping efficiency. GCLs conform properly to subgrade contours, decreasing the threat of cracking and leakage over time.

5. Underground Storage Tank Liners

Acts as a secondary containment layer to seize any leaks or spills from gasoline or chemical tanks. Especially perfect for environmental safety round petroleum storage and hazardous fabric facilities.

6. Environmental Remediation

GCLs are deployed in contaminated sites, brownfields, and industrial cleanup areas to isolate pollution and stop similarly contamination. Their self-healing houses beautify safety even in difficult area conditions.
