- BIS Certification for Polymeric Strip or Geostrip Used as Soil Reinforcement (IS 17372:2020) ensures compliance, safety, and reliability for soil stabilization structures.
- The ISI Mark for IS 17372:2020 confirms that geostrips meet India’s quality and performance standards.
- Diligence Certification provides end-to-end support — from testing to BIS registration and license renewal.
Introduction
In 2024, an infrastructure contractor from Gujarat lost a ₹10 crore government tender for a highway retaining wall project.
The reason? Their Polymeric Strips used for soil reinforcement lacked BIS Certification under IS 17372:2020.
Even though the materials had passed internal testing, the absence of the ISI mark made their bid invalid.
Such rejections are becoming common as government projects now strictly demand ISI-marked soil reinforcement products to comply with the BIS Act, 2016.
BIS Certification for Polymeric Strip or Geostrip – Soil Reinforcement specifies not just safety and performance, but also ensures the product complies with the latest quality standards for civil engineering in India.
Diligence Certification supports manufacturers through each step, including product testing and the application process to obtain and renew the BIS license for IS 17372:2020
What is IS 17372:2020?
Indian Standard IS 17372:2020 is a standard established by the Bureau of Indian Standards (BIS) for Polymeric Strip or Geostrip Used as Soil Reinforcement in civil engineering works.
Polymeric strips are critical to the performance of reinforced soil walls, embankments, slopes, and retaining systems as they provide structural stability, decreased earth pressure, and improved performance over time.
Key Technical Parameters of IS 17372:2020
- Material Composition:
Polymeric strips must be made from high-quality polymers like polyester or polyethylene with stabilizers to resist UV and environmental degradation. - Tensile Strength and Elongation:
The standard defines minimum tensile load, elongation percentage, and creep rupture properties to ensure durability. - Dimensional Tolerances:
Specifies strip width, thickness, and edge uniformity for consistent performance. - Weathering and Durability Tests:
Strips undergo accelerated weathering, temperature, and chemical resistance tests. - Marking and Identification:
Every certified strip must bear the ISI mark, manufacturer’s name, batch number, and license number. - Workmanship:
The product should be free from defects, cracks, or impurities that affect performance in the field.
Why BIS Certification for Polymeric Strip or Geostrip Used as Soil Reinforcement is Essential
1. Legal Compliance under BIS Act, 2016
Manufacturers cannot produce or sell polymeric geostrips in India without a valid BIS license under IS 17372:2020.
Violating this regulation can lead to penalties, confiscation of goods, or plant shutdown.
2. Assurance of Structural Safety
BIS-certified polymeric strips are tested for tensile strength, elongation, and creep rupture, ensuring they can withstand long-term soil and load pressures.
3. Tender Eligibility
All public infrastructure and highway projects now require ISI-marked materials.
Without the ISI mark, your product cannot be used in NHAI, PWD, or Smart City tenders.
4. Brand Trust and Customer Confidence
The ISI mark enhances brand reliability and customer trust.
Distributors and contractors prefer sourcing certified materials to avoid compliance issues.
5. Export Recognition
BIS certification is recognized by foreign buyers as proof of product quality, helping Indian manufacturers access global infrastructure projects.
Understanding the ISI Mark for Polymeric Strip or Geostrip Used as Soil Reinforcement
The ISI mark is more than a label — it’s a symbol of safety, compliance, and quality.
For products certified under IS 17372:2020, the ISI mark guarantees:
- Dimensional and tensile accuracy
- Weather resistance and chemical stability
- Long-term load-bearing capacity
- Traceability through batch code and license number
Every strip bearing the ISI mark can be traced back to its manufacturer, ensuring full accountability in quality assurance.
