AGGREGATES WITH RECYCLED CONTENT
FOR COMMERCIALLY VIABLE, SCALABLE RAC
Pressure is growing.
On aggregate producers.
On concrete plants.
Across the entire
construction materials industry.
The construction industry needs solutions that conserve resources
without compromising industrial performance.
UNTIL NOW.
GRAVELMIX
MAKES RAC SIMPLE AND PREPARES
AGGREGATE PRODUCERS FOR THE FUTURE
FOR AGGREGATE PRODUCERS, THE FUTURE IS BECOMING MORE CHALLENGING
Permits are becoming harder to obtain,
extraction sites are finite, and primary raw materials are under increasing pressure.
Securing sites for the long term requires new approaches.
FOR CONCRETE PRODUCERS, THE DEMAND FOR RAC WILL INCREASE
Yet producing it remains unattractive. Technically feasible, but too complex:
Recycled aggregates mean additional fractions and material flows – requiring extra silo compartments, more complex logistics and production downtime.

HOW DOES GRAVELMIX WORK?
THE PATENTED
GRAVELMIX PROCESS
GRAVELMIX shifts the blending of virgin and recycled material upstream into the gravel or stone plant and away from the concrete plant’s limited storage capacity.
There, natural aggregates are blended with recycled material before being washed and classified together.
THE SOLUTION IS
AS SIMPLE AS IT IS SMART
GRAVELMIX moves the critical process step upstream, thereby solving the fundamental structural problem.

THE SOLUTION IS
AS SIMPLE AS IT IS SMART
GRAVELMIX moves the critical process step upstream, thereby solving the fundamental structural problem.
THE RESULT
A fully pre-blended product with defined recycled content.
CONCRETE PLANTS ARE SUPPLIED WITH THESE
READY-TO-USE FRACTIONS
The number of aggregate fractions required at the concrete plant remains the same as for conventional concrete.
This means concrete plants can operate without special logistics or production downtime.
Recycled sand, which until now has been difficult to use in RAC, is returned to the value chain.

GRAVEL AND CRUSHED STONE PRODUCERS
THE FUTURE OF CONCRETE DOESN’T BEGIN AT THE CONCRETE PLANT.
IT BEGINS WITH YOU.
With GRAVELMIX, you can:
• extend the productive life of your sites by many years or even decades
• reduce the extraction of primary raw materials by 20 – 30%
• develop a new business segment as a supplier of GRAVELMIX aggregates to concrete plants
• benefit directly from the significant growth potential of RAC
• increase profitability and secure the long-term viability of your site
You evolve from a raw material supplier into an active driver of a new construction standard.
We would be pleased to show you how GRAVELMIX can be implemented at your plant -both technically and economically.
CONCRETE PLANTS
RAC – SIMPLE, COST-EFFECTIVE AND SCALABLE
With GRAVELMIX:
• RAC can be produced as a true drop-in solution for the first time: the supplied aggregate fractions already contain recycled material
• RAC can be produced without additional silo compartments
• no complex special logistics are required
• recycled material can be integrated into existing plant logistics without production downtime
• no modifications to the existing infrastructure are required
• planning certainty is increased
• you benefit from the significant growth potential of RAC
• you gain an economically viable alternative to conventional concrete
GRAVELMIX is an industrial solution that is available for immediate implementation.
DEMOLITION AND RECYCLING COMPANIES
FROM WASTE DISPOSAL CONTRACTOR TO RAW MATERIAL PARTNER
GRAVELMIX:
• upgrades recycled material into a sought-after raw material
• returns recycled sand fully to the material cycle

Meet the People
Behind GRAVELMIX
Thomas Ottl and Thomas Vilgertshofer
30 years of proven experience in demolition, recycling, and construction.
Thomas Ottl and Thomas Vilgertshofer bring more than three decades of hands-on experience across the entire value chain – from demolition and the processing of mineral material streams to concrete production and new construction.
Thomas Ottl conceived GRAVELMIX. Thomas Vilgertshofer is his long-time companion, strategic sounding board, and indispensable business partner. Together, they developed GRAVELMIX to a market-ready, industrial-scale solution.
„I’d be thrilled if we’ve managed to find something that saves resources and can be implemented at an industrial scale.“
(Thomas Ottl, founder of GRAVELMIX)
RESOURCE WASTE IN CONSTRUCTION IS IMPOSSIBLE TO IGNORE
In his day-to-day work, Thomas Ottl repeatedly watched high-quality concrete from demolition leave the site by truck – sometimes in volumes of 40,000 tons – sent for landfill.
“The amount of material, energy, and logistics involved was completely out of proportion. Why are we disposing high-quality mineral material instead of feeding it straight back into concrete production?”
For years, demolition material was treated as a low-grade input in many applications.
So Thomas Ottl started testing a different approach on his own gravelplant site pouring multiple slabs with recycled-concrete mixes to prove it in practice. That’s when the idea for GRAVELMIX was born.
