ROMEX: The Pioneers of TRASS in Hardscape Systems
15 years ago ROMEX became the first company in the world to guarantee the full functionality of a complete permeable hardscape system. This breakthrough involved integrating three key components: a water-permeable bedding material containing the rare German trass mineral, a thinset-like bonding slurry with the same trass content, and a pavement joint mortar designed to meet the required load class. While these components had been used individually in construction for years, ROMEX was the first to combine them into a proven, reliable system.
The Legacy of Trass: A Natural Mineral with a Roman Heritage
The mineral trass has a history that dates back to the ancient Romans, who recognized its exceptional qualities for construction. It was mined in only two locations in Germany, and even today, a trass mortar can only bear that name if it contains at least 20% of this rare mineral from one of these historic sites. Anything else is not a standardized trass mortar.
ROMEX TRASS BED takes this legacy a step further, being produced in the USA with a minimum of 25% of the rare trass mineral, ensuring it meets the highest quality standards while being proudly made in North America.
Why Trass Makes a Difference in Permeable Hardscapes
Trass is a game-changer in mortar technology. One of its key benefits is its ability to reduce hydrated lime in Portland cement, significantly lowering the alkalinity of the mortar mix. This results in:
- Increased suppleness for better workability.
- Improved water-holding capacity, preventing premature drying.
- Enhanced durability for long-lasting hardscape installations.
Additionally, trass is an environmentally responsible material. It requires minimal energy for production—mined in an open pit, air-dried, and ground, without the energy-intensive burning process associated with cement. This significantly reduces CO2 emissions, making it a sustainable choice for modern hardscape construction.
Commitment to Quality and Sustainability
At ROMEX, we prioritize both performance and sustainability. While the technology and additives for our products originate from Germany, the aggregates used in our grouting materials are sourced 100% from American suppliers. This ensures the highest quality materials while supporting the local economy.
By choosing ROMEX, hardscape professionals can rely on a fully functional, permeable system backed by decades of innovation, expertise, and environmental responsibility. Our commitment to using trass in our bedding and bonding materials not only improves durability and permeability but also aligns with the growing demand for sustainable construction solutions.
