Auroguard's Non-Woven Geotextile fabrics are needle-punched polypropylene separation and filtration layers for road subgrade stabilization, drainage systems, retaining walls, and erosion control. Random fibre entanglement provides high in-plane drainage capacity while retaining soil particles meeting IS 16352 requirements. Widely specified in NHAI and PMGSY road construction for subgrade separation preventing clay migration into granular base layers.

Frequently Asked Questions
What is IS 16352 for geotextiles?
IS 16352 is the Indian Standard for geosynthetic products — geotextiles and related items — specifying test methods for tensile strength, CBR puncture, apparent opening size and other properties for civil infrastructure applications.
What GSM geotextile is specified for road subgrade?
MORTH Section 300 typically specifies 150–300 GSM non-woven geotextile for road subgrade separation layers. For PMGSY rural roads, 100–200 GSM is commonly specified depending on subgrade CBR conditions.
Does Auroguard supply geotextile for NHAI projects?
Yes. Auroguard supplies IS 16352 and MORTH Section 300 compliant non-woven geotextiles for NHAI national highway, PMGSY rural road and state PWD road construction projects.
