1mm Geomembrane Sheet Price
Geomembranes are the unsung heroes of modern civil and environmental engineering. In Pakistan, the demand for reliable waterproofing liner solutions for agriculture, aquaculture, and waste management is booming. Among the various thicknesses, the 1mm geomembrane sheet strikes an ideal balance between performance, durability, and cost-effectiveness for a vast range of applications.
This comprehensive guide breaks down the price structure of 1mm geomembrane liners in the Pakistani market, helping you budget accurately for your next project, whether it’s a small fish pond or a large irrigation canal lining.
Understanding the 1mm Geomembrane Standard
The 1mm (equivalent to approximately 40 mils) thickness is a globally recognized standard for containment projects that require substantial puncture resistance and longevity without the heavy material cost of thicker liners (like 1.5mm or 2.0mm).
The two most common materials you will encounter in Pakistan are:
HDPE Geomembrane (High-Density Polyethylene): Known for its excellent chemical resistance, UV stability, and high tensile strength. It is the primary choice for landfill liner systems and large water reservoirs.
PVC Geomembrane (Polyvinyl Chloride): Famous for its superior flexibility, which makes it easier to install over complex, irregular surfaces. It is often preferred for basement waterproofing barrier projects.
For a 1mm thickness, HDPE geomembrane is often the baseline for geomembrane project cost assessments in the local industry.

Pricing for geomembranes in Pakistan is dynamic, heavily influenced by global polymer prices and local supplier logistics. The rates provided below are estimates and should be verified with official quotes for a specific project. Prices are typically quoted per square meter (sq.m)
| Material Type | Thickness | Estimated Price Range (PKR/sq.m) – Material Only | Estimated Price Range (USD/sq.m) – Material Only | Typical Applications |
| HDPE Geomembrane | 1.0mm | PKR 200 – PKR 350 | $0.70 – $1.25 | Reservoirs, Large Ponds, Containment pond liner, Waste Pits |
| PVC Geomembrane | 1.0mm | PKR 250 – PKR 450 | $0.85 – $1.60 | Small Ponds, Waterproofing barrier, Complex Geometries |
| LLDPE Geomembrane | 1.0mm | PKR 280 – PKR 480 | $0.95 – $1.70 | Aquaculture, Flexible Tank Linings, Rooftop Waterproofing |
Note: Exchange rates fluctuate. USD prices are based on approximate current market conditions and are often used by suppliers dealing in imported raw materials.
Key Factors Driving the Geomembrane Price
The final geomembrane price you pay is a comprehensive figure that extends beyond the per-square-meter rate of the material. Understanding these variables is key to negotiating the best deal:
1. Material Quality and Certification
Liners manufactured from virgin resin (which meet international standards like GRI-GM13) are more expensive than those made from recycled materials. The higher cost translates to superior chemical resistance and a much longer lifespan (often 50+ years), justifying the initial investment cost.
2. Project Scale and Order Quantity
Large-scale projects requiring thousands of square meters benefit from significant bulk pricing. Suppliers and manufacturers offer economies of scale, meaning the per-unit material cost decreases substantially for massive orders (e.g., a 5,000 sq.m pond versus a 50,000 sq.m reservoir).
3. Installation and Logistics
This is a critical component of the total geomembrane project cost:
Geographical Location: Transporting heavy rolls to remote sites across Pakistan (e.g., Balochistan or remote Northern Areas) increases transport cost significantly.
Seaming and Welding Labor: Specialized geomembrane welding requires certified technicians and equipment (hot wedge welders). Installation costs typically range from PKR 50 to PKR 150 per sq.m, depending on the project complexity and slope angles.
4. Additional Accessories
Most projects require supplementary items that add to the cost:
Geotextile Underlayment: Placing a non-woven geotextile layer (often PKR 40–80/sq.m) beneath the geomembrane is essential for protecting the 1mm liner from subgrade punctures.
Anchor Trench Materials: Materials for securing the edges.
Testing and Quality Assurance (CQA): Essential quality control measures like air pressure testing of seams.
Finding Suppliers for your Geomembrane Liner
Finding a reputable geomembrane supplier is vital. Major cities in Pakistan, especially Lahore and Karachi, serve as key hubs for the geosynthetics market.
Manufacturers/Importers in Lahore: Several established companies operate from Lahore, offering both imported and locally manufactured geomembranes. They typically provide complete supply and installation services for waterproofing solutions.
Dealers in Karachi: Karachi, as a major port city, is a hub for importers, offering direct access to internationally sourced high-quality HDPE liner products.
Always request a comprehensive quote that separates the material cost, installation labor, and auxiliary materials for full transparency.
FAQ’S
What is the average price of a 1mm geomembrane sheet in Pakistan?
The price of a 1mm geomembrane sheet in Pakistan typically depends on the material (HDPE, LDPE, or PVC), brand, and quantity. On average, prices are quoted per square meter and may vary based on project size and delivery location.
Is 1mm geomembrane suitable for ponds and water tanks?
Yes, 1mm geomembrane sheets are commonly used for fish ponds, irrigation reservoirs, and water storage tanks. They offer a good balance between flexibility, durability, and cost-effectiveness for medium-depth applications.
Does installation cost affect the total price of a 1mm geomembrane?
Yes. The total cost includes material price, surface preparation, welding, seam testing, and labor. Professional installation ensures leak-proof performance and long service life, which adds value to the overall investment.
Which is better at 1mm thickness: HDPE or LDPE geomembrane?
At 1mm thickness, HDPE geomembrane offers higher strength and chemical resistance, while LDPE geomembrane provides better flexibility. The choice depends on the application, environmental conditions, and budget.
