Geomembrane

Geomembrane - The Ultimate Solution for Environmental Protection in UAE

Geomembranes are low permeability synthetic membranes used as liners or barriers in construction projects and environmental containment applications. With rapid infrastructure development and focus on environmental sustainability in UAE, the demand for quality geomembranes has increased significantly. As a leading geomembrane manufacturer in UAE, we produce high-grade geomembranes that cater to diverse containment needs across industries.

Introduction to Geomembranes

Geomembranes are flexible polymeric sheets designed as barriers against fluid migration. They are made from materials like polyethylene (PE), polyvinyl chloride (PVC), ethylene propylene diene monomer (EPDM) and more. The sheets are available in various thicknesses like 0.75mm, 1mm, 1.5mm, 2mm, 3mm, etc. based on the application requirements.

Geomembranes provide extremely low permeability which makes them ideal solutions for pollution containment. They are resistant to weathering, puncture, tear and impact. With welded seams, they form continuous liners for maximum effectiveness in preventing leaks. Their flexibility allows easy installation and conformation to underlying topography.

Our geomembranes are manufactured using virgin resins and advanced extrusion technology. They conform to international product standards like GRI-GM13 and undergo rigorous quality testing. We stock a wide range of geomembrane products in various thicknesses to meet diverse engineering needs.

Applications of Geomembranes

Geomembranes have become indispensable in modern infrastructure projects due to their unmatched barrier performance. Some major applications include:

Landfill Liners

Landfill geomembrane liners prevent leachate contamination of soil and groundwater. A composite liner system with clay and geomembrane is installed at the base and walls of landfills. 1mm HDPE geomembranes are commonly used due to strength, chemical resistance and ease of welding.

Mining

Geomembrane liners are installed at mine tailings dams, leach pads and ponds to prevent seepage of contaminated water into the environment. HDPE, LLDPE and PP membranes provide long-term performance in mining applications.

Stormwater Management

Retention ponds, detention basins and artificial recharge basins utilize geomembrane liners to prevent infiltration and store stormwater for reuse. HDPE liner systems withstand weathering and prevent groundwater contamination.

Wastewater Treatment

Geomembranes are used in aeration lagoons, sewage lagoons, sludge drying beds and other wastewater facilities. LLDPE, PVC and PP geomembranes provide chemical and UV resistance for long service life.

Aquaculture

HDPE and LLDPE pond liners allow economical construction of aquaculture ponds. Geomembranes contain water efficiently while providing puncture and tear resistance against underwater loads.

Agriculture

Farmers across UAE utilize geomembranes for better water management. Lining of canals, reservoirs and water channels optimizes water usage and prevents losses.

Tunnels & Underground Structures

Sprayed PE, PP and PVC membranes control water infiltration and provide chemical resistance in tunnels, underground parking garages and below ground structures.

With their versatility, durability and barrier performance, geomembranes provide reliable, sustainable solutions across industries in UAE.

Benefits of Using Geomembranes

Geomembranes provide the following advantages that make them indispensable for modern construction projects:

• Extremely low permeability compared to soils - prevents fluid migration and contamination
• Continuous fluid barrier with strong welded seams
• Flexibility - ease of installation and conformation to ground settlement and underlying topography
• Resistant to chemicals, bacteria, puncture and weathering
• Cost-effective containment solution compared to compacted clay liners
• Lightweight and easy to transport and deploy
• Long design life with proper installation
• Sustainable solution for environmental protection
• Customizable formulations for specific project needs

With their unmatched barrier performance, durability and reliability, geomembranes provide efficient containment solutions for infrastructure development and environmental protection across UAE.

Types of Geomembranes

We manufacture and supply an extensive range of geomembrane products to cater to diverse engineering applications:

Polyethylene (PE) Geomembranes

PE geomembranes are manufactured from polyethylene resins like HDPE and LLDPE. They provide:

• Easy welding for strong, continuous seams
• Cost-effectiveness

HDPE geomembranes are commonly used for landfills, mining, stormwater management, etc. LLDPE variants are suitable for exposed installations due to good weathering resistance.

Polyvinyl Chloride (PVC) Geomembranes

PVC geomembranes provide:

• High strength and tear resistance
• Excellent chemical resistance
• Good withstand temperatures up to 140°F
• UV and weathering resistance
• Long design life - up to 50 years

They are suitable for wastewater treatment, chemical containment, tunnel applications, etc.

Polypropylene (PP) Geomembranes

PP geomembranes exhibit:

• High temperature resistance - up to 250°F
• Excellent chemical compatibility
• Good puncture and impact resistance
• Low coefficient of expansion
• Cost-effectiveness

They are used for mining, landfills, industrial waste containment, etc.

Ethylene Propylene Diene Monomer (EPDM) Geomembranes

EPDM geomembranes provide:

They are suitable for exposed installations like canal lining, reservoirs, etc.

We manufacture geomembranes in various thicknesses ranging from 0.75mm to 3mm in each type to suit the engineering requirements of projects across UAE.

Geomembrane Manufacturing Process

We utilize state-of-the-art extrusion lines and world-class testing infrastructure to produce high quality geomembranes.

Raw Material Sourcing

Polymeric resins like HDPE, LLDPE, PVC, etc. are sourced from certified suppliers and thoroughly tested before acceptance.

Extrusion

The raw materials are mixed, melted and extruded into continuous sheets using advanced extrusion lines. Process controls like temperature, screw speed, thickness controls, etc. are automated to ensure consistency.

Cooling & Winding

On exiting the die, the hot extrudate is cooled uniformly in a controlled manner before being wound over large reels. This provides proper sheet crystallization.

Quality Testing

The geomembrane rolls undergo stringent testing as per international standards to ensure they are free of flaws and meet product specifications. Tests performed include thickness, specific gravity, tensile properties, tear and puncture resistance, etc.

Final Inspection and Packaging

Flaw-free rolls that pass all tests are trimmed, visually inspected and packed for storage and transport. We maintain full traceability throughout the production and testing process.

Our state-of-the-art manufacturing infrastructure and rigorous quality control ensure that clients get highly reliable geomembrane products for critical containment applications.

Geomembrane Installation

Proper installation of geomembranes is crucial to realize their full performance and life expectancy in projects. Our in-house installation experts take care of end-to-end geomembrane deployment, conforming to international codes and specifications.

Site Preparation

The subgrade is properly graded and compacted. A smooth, uniform and stable surface is prepared to receive the liner.

Deployment

The geomembrane rolls are inspected, unwrapped and laid out over the surface. Temporary loading and anchoring may be required on slopes and windy conditions. The sheets are overlapped and interconnected with dual track welds.

Seam Welding

Seams are at the heart of the containment capacity of installed geomembranes. Our experts use automated fusion welders to create continuous, strong seams that are as strong as the parent material. Destructive and non-destructive tests are conducted for quality assurance.

Penetrations and Terminations

Boots and specialized fabrication are used to neatly weld the geomembrane with protruding penetrations, drains, piping, etc. Terminations at appurtenances, embedment in trenches, anchoring are carried out according to specifications.

Protection Layer

Once installed, the geomembrane is covered by a protection layer of sand, geotextile or another material to prevent damage.

With decades of installation experience, we ensure complete impermeability and maximum performance life of the installed geomembranes in projects across UAE.
