About us
Not just assembled. Made in India.
MADE IN INDIA
Polymer concrete drainage has long been specified in Europe and imported into India. WTI produces the channel bodies and the stainless gratings on our own floor at the 111,000 sft Jaipur plant - not bought in as parts and finished here.
Lead times, tolerances and cost sit under one roof. For a specifier that removes the two things that usually complicate specifying polymer concrete in India: import lead time, and landed cost.
