Fast Facts
The geosynthetics market size stood at US$27.16 billion
in 2018. It is set to reach US$45.25 billion by 2026,
exhibiting a CAGr of 6.6%.
Asia Pacific is expected to witness substantial growth
in near future due to rise in the novel and new
infrastructure renovation & development.
Growing construction activities coupled with rising
applications in erosion control, landfills, separation
