- BIS Certification for geogrids used in Flexible Pavements indicates that the product meets the requirements of IS 17371:2020, which confirms that the geogrid is durable, has adequate tensile strength and is a trusted outcome for road construction.
- The ISI Mark provides a declaration on geogrids as a finished product that will perform consistently under heavy traffic and environmental stress.
- Diligence Certification will assist the manufacturer, between testing the geogrid, documentation and BIS license approval under IS 17371:2020.
Introduction
In 2024, a Pune-based manufacturer of road materials was disqualified on a government project because their Geogrids for Flexible Pavements did not have the mandated Bureau of Indian Standards (BIS) Certification under IS 17371:2020.
Although the manufacturer met the quality standards in their internal laboratory testing for their geogrid products, the government tender committee rejected the bid because of the BIS Act, 2016, which requires that infrastructure and highways construction products been ISI-marked. This case is not unique.
Across India, geosynthetic manufacturers are losing valuable tenders and contracts solely because they fail to achieve the required BIS certification for their geogrid products. Obtaining a BIS License under IS 17371:2020 would allow the manufacture, sale, and capitalization of tender projects — establishing the manufacturer’s credibility with authorities, builders, and even international clients.
Diligence Certification will personally manage the entire process from sample testing, documentation, leading factory audit, and BIS license approval ensuring the process is executed, effective, and on time.
What is IS 17371:2020?
IS 17371:2020 is the Indian Standard published by the Bureau of Indian Standards (BIS) that stipulates the specifications, testing/measurements, and performance requirements for Geogrids utilized in Flexible Pavement Construction.
Geogrids are synthetic geosynthetic materials created from polymeric compounds for the purpose of soil reinforcement and to help distribute load in roadway pavements.
The standard ensures that Geogrids have sufficient tensile strength, elongation, junction efficiency, and resistance to degradation from the environment.
Key Technical Requirements under IS 17371:2020
1. Material Composition
Geogrids must be manufactured using high-grade polymeric materials such as polypropylene, polyethylene, or polyester, ensuring durability and chemical resistance.
2. Tensile Strength and Junction Efficiency
The standard specifies the minimum tensile strength for longitudinal and transverse directions.
The junction efficiency ensures the grid intersections are capable of transferring load effectively without rupture.
3. Elongation at Maximum Load
The elongation should remain within the prescribed range to prevent pavement deformation and structural failure during heavy vehicular load.
4. Durability Tests
Geogrids undergo ultraviolet exposure, thermal aging, and chemical resistance tests to confirm performance under Indian climatic conditions.
5. Dimensional Stability
Uniform spacing, rib thickness, and node configuration are mandatory for structural reliability during installation and service life.
6. Marking and Labeling
Each roll of geogrid must bear:
- ISI mark,
- Manufacturer’s identification code,
- Batch number,
- Reference to IS 17371:2020.
Only BIS-licensed manufacturers are permitted to use the ISI mark.
Why BIS Certification for Geogrids for Flexible Pavements is Essential
1. Legal Requirement under BIS Act, 2016
Manufacturers cannot produce or sell Geogrids for Flexible Pavements without obtaining BIS certification under IS 17371:2020.
Any violation can lead to penalties, seizure of stock, and cancellation of operations as per Section 17 of the BIS Act.
2. Structural Safety and Quality Assurance
Certified geogrids undergo mechanical testing for strength, creep behavior, and durability, ensuring long-term pavement stability and load-bearing performance.
3. Tender and Market Eligibility
Government and infrastructure authorities, including NHAI, CPWD, and PWD, accept only ISI-marked geogrids for flexible pavement construction projects.
4. Consumer Confidence and Brand Credibility
The ISI mark enhances brand reliability among engineers, contractors, and procurement agencies, helping manufacturers expand their market presence.
5. Export Recognition
International clients and government projects prefer BIS-certified geogrids as proof of compliance with Indian quality benchmarks.
Understanding the ISI Mark for Geogrids for Flexible Pavements
The ISI Mark is a symbol of conformity and safety that assures users the product meets Indian Standard IS 17371:2020 in every batch.
It confirms:
- Dimensional uniformity and material quality
- Adequate tensile strength and junction integrity
- Resistance to heat, moisture, and chemical exposure
- Product traceability through batch coding
Every ISI-marked roll can be traced to its licensed manufacturer, ensuring accountability and authenticity.
