About Viaza Stone
How it started
Our story began in the mountains of Taza, where Moussa grew up surrounded by the remarkable landscapes that would later inspire his life's goal.
On his way to school, he watched immense blocks of stone leave the surrounding quarries on heavy trucks. These renowned Taza quarries hold a noble natural material shaped over millions of years within one of the region's most impressive rock formations.
That early connection grew into a profound passion for natural stone, its distinctive character, and its timeless beauty.

The foundation
“Noble material for noble client”
Driven by his passion, Moussa founded UNIVMAR, a Moroccan company specialising in the quarrying, processing, and distribution of marble and natural stone.
Its sustained growth is built on accumulated expertise, technical know-how, and an unwavering commitment to quality—qualities that have made the company a distinctive and trusted name in the industry.
The story of Viaza


A path, a journey, a connection—joined to the final letters of Taza.
VIAZA was born from the meeting of history, natural stone, and Moroccan identity. It draws inspiration from ancient civilisations—particularly the Greeks, who elevated marble into an art form—and from Taza, a land renowned for its rich deposits and exceptional varieties of natural stone.
The name celebrates the journey of stone, from its natural origins to its finest architectural expression.

At the source
A responsibility as enduring as the stone.
In the heart of the Taza mountains, our quarry brings Morocco’s natural heritage together with advanced extraction technologies and disciplined site management.
State-of-the-art equipment and carefully controlled cutting methods help preserve the stone’s natural qualities, optimise resources, and minimise material waste.
Regular staff training, personal protective equipment, machinery inspections, and rigorous risk assessments guide every stage from extraction to block loading.
We reduce dust emissions, optimise water and energy use, recover stone residues, and plan for responsible site management and progressive land rehabilitation.
Our long-term vision
At VIAZA, extracting a noble natural stone comes with an equally important responsibility: to respect the generations to come.
