Learn About Us
Circular Economy

Converting industrial by-products into construction materials, reducing landfill waste and natural resource demand.

Scientific Process

Advanced pelletisation and chemical activation produce reliable engineered sand.

IS Compliant

All FAB Sand products are manufactured and tested per Indian Standards IS 383 and IS 2386.

Local Supply

Manufactured close to demand centres, reducing transport costs and carbon emissions.

The Problem

River Sand
is Running Out.

Excessive extraction of natural river sand is depleting ecosystems, raising costs, and disrupting supply chains across India's booming construction sector.

The Source

Fly Ash —
An Abundant
By-Product.

Thermal power plants produce millions of tonnes of fly ash each year. Left unused, it accumulates in ash ponds, wasting land and polluting groundwater.

India generates 340.11M+ tonnes of fly ash every year
Fly ash utilisation is a government policy mandate
Pravara converts this waste into a valuable resource

What Makes FAB Sand Different?

Well Graded

Every batch, produced under controlled conditions, ensures graded particle sizing from 4.75mm to 0.075mm and uniform quality — unlike variable natural sand.

Precision Engineering

Proprietary processing techniques transform raw fly ash into stable, sand-like material with engineered properties.

Rigorous QC

Each batch undergoes testing per IS 2386 before leaving the facility. A Certificate of Analysis is provided with every shipment.

Local Production

Manufactured close to demand centres, reducing transport costs and supply chain carbon emissions significantly.

How It's Made

The FAB Sand Manufacturing Process

From industrial fly ash to precision-engineered sand — a controlled 5-step process.

1
Fly Ash Collection

Industrial fly ash is sourced from thermal power plants — the raw material for FAB Sand.

2
Raw Material Processing

Fly ash is pre-processed, screened, and chemically treated to activate binding properties.

3
Pelletisation

Controlled pelletisation forms granules of precise size and density — mimicking sand.

4
Curing & Hardening

Granules are cured under controlled conditions to achieve structural stability and strength.

5
Quality Testing & Dispatch

Every batch is tested per IS 383 / IS 2386. A CoA is issued before dispatch to the project site.

Sustainability

Why FAB Sand Matters
for the Planet

Thermal power plants generate vast volumes of fly ash. Excessive river sand extraction depletes natural ecosystems. FAB Sand bridges both — by converting an industrial waste into a valuable construction material.

  • Reduces dependency on natural river sand mining
  • Promotes beneficial utilisation of industrial fly ash
  • Lowers transport emissions through local manufacturing near demand sites
  • Supports India's circular economy objectives
  • Ensures responsible resource management for future generations
