Engineering the Future of Fly Ash
Since 2006, Hi-Tech Fly Ash (India) Private Limited has pioneered classified fly ash processing in South India, delivering engineered supplementary cementitious materials trusted by cement manufacturers and infrastructure projects across the world.
Built on Engineering. Trusted Worldwide.
Hi-Tech Fly Ash (India) Private Limited was established in 2006 with a vision to engineer high-performance classified fly ash for the global construction industry. Today, we operate one of India's largest independent fly ash classification and export facilities, strategically located just 10 km from V.O. Chidambaranar Port, Tuticorin, supplying cement manufacturers, ready-mix concrete producers and infrastructure projects across 25+ countries worldwide.
Unlike facilities located within power plants, HITEPOZZO® operates as an independent processing facility, giving us complete control over raw material selection, product engineering and long-term supply reliability. Designed, built and operated by our own engineering team under the Thiraviam Group, our facility reflects nearly two decades of engineering expertise and an unwavering commitment to consistent product performance.
Built by Engineers, Not Traders
Hi-Tech Fly Ash did not emerge from a trading background. It was founded and built by engineers — professionals with six decades of hands-on industrial experience across some of India's most demanding projects.
Engineering Heritage
Thiraviam Engineering Pvt Ltd is the foundation of the group, with decades of heavy industrial expertise built project by project across Southern Tamil Nadu. As an NTPC & BHEL approved vendor recognised by India's largest power and engineering corporations, the group built a track record in full EPC turnkey contracting and critical spare manufacturing long before entering fly ash — the same engineering discipline that later shaped how the Hi-Tech Fly Ash facility itself was designed and run.
Engineering Expertise
That engineering track record spans turnkey project execution and heavy material handling across some of India's most demanding industries, including:
- ▸ Power Plants – EPC contracting, ash handling and plant engineering
- ▸ Ports & Bulk Material Handling – Conveyor, stacker reclaimers and bulk logistics
- ▸ Cement Industry – Material handling and process engineering solutions
- ▸ Heavy Industry – Copper smelters, chemical plants, fertilizer facilities and etc
Core engineering capabilities include:
- ▸ Full EPC turnkey contracting
- ▸ Critical spare manufacturing & supply
- ▸ Bulk material handling systems
- ▸ Coal, ash handling & stacker reclaimer systems
These decades of engineering expertise formed the technical foundation that was later applied to designing and operating HITEPOZZO®'s independent fly ash classification facility.
Global Engineering Collaborations
Engineering excellence strengthened through collaboration with globally recognized industrial technology leaders.
These collaborations introduced world-class bulk material handling, process engineering and industrial technologies that continue to influence HITEPOZZO®'s approach to fly ash classification, plant design and process optimization.
From Engineering to Fly Ash
Decades of engineering experience in thermal power plants and bulk material handling revealed an opportunity others overlooked. While fly ash was widely treated as an industrial by-product, the Thiraviam Group recognised its potential as a high-performance supplementary cementitious material. Combining its expertise in process engineering, material handling and plant design, the group established Hi-Tech Fly Ash (India) Private Limited in 2006 to engineer consistent, internationally compliant classified fly ash for the global construction industry.
“Our journey into fly ash wasn't driven by market trends, but by engineering expertise and a vision to unlock its true potential.”

The Vision Behind HITEPOZZO®
John Vasigaran
Founder & Managing Director
Long before Hi-Tech Fly Ash was established, John Vasigaran recognised that fly ash was more than an industrial by-product. Drawing on decades of engineering experience in thermal power plants, bulk material handling and industrial process engineering, he saw the opportunity to transform fly ash into a high-performance supplementary cementitious material for modern infrastructure.
That vision became Hi-Tech Fly Ash (India) Private Limited in 2006 — an independent engineering company built to manufacture internationally compliant classified fly ash with consistent quality and reliable supply. Today, HITEPOZZO® exports classified fly ash and ultra fine fly ash to infrastructure, cement and concrete industries across more than 25 countries, guided by the same engineering principles on which the company was founded.
“Engineering creates value only when it solves real-world problems. HITEPOZZO® was built on that belief.”
