HDPE geomembrane liners are the top choice for a wide range of lining projects due to their exceptional resistance to various solvents. As the most widely used geomembrane liner globally, HDPE liners are ideal for applications such as aquaponics, ponds, troughs, bioswales, canals, drainage systems, mud runners, slip-n-slides, and other water retention and containment uses. They are also employed in root barriers, piping systems, and slip sheets.

Indian Standard IS 16352:2020

Indian Standard IS 16352:2020 specifies the requirements for geosynthetics, focusing on High-Density Polyethylene (HDPE) geomembranes used for lining applications.

• IS 16352:2020 covers both smooth and textured HDPE geomembrane liners for various applications, including canals, ponds, reservoirs, water features, landfills, hazardous waste management, solid waste management, and industrial effluents. It is also used for waterproofing large underground civil structures such as basements, road underpasses, tunnels, foundations, and roofs/terraces.

• The standard outlines tests designed to ensure the quality and workmanship of HDPE geomembranes. While these tests are primarily intended for natural aqueous systems, additional tests may be required to assess chemical resistance and durability based on specific environmental conditions and performance needs.

Benefits of Securing ISI Mark Certification for HDPE Geomembranes Used in Lining Applications

Here are the key benefits of getting ISI Mark certification:

• Government Compliance: The ISI mark indicates that your HDPE geomembranes meet stringent quality standards set by the government, ensuring regulatory compliance.

• Mandatory Certification: For HDPE geomembranes used in lining applications, ISI certification is compulsory. Non-compliance can lead to penalties, including material seizure and substantial fines.

• Enhanced Market Competitiveness: Certification boosts your product’s marketability by verifying that it adheres to high-quality standards, improving its competitiveness.

• Customer Trust and Preference: ISI certified products are preferred by customers for their guaranteed safety and quality. Certification helps you build trust and confidence with potential buyers.

• Market Benchmarking: The ISI mark sets a benchmark for quality, helping to elevate your product’s standard and market value.
