New Construction
THE FUTURE OF CONCRETE
Urban Mining,
ECONOMICALLY
VIABLE
Recycled aggregate concrete is a cornerstone of circular construction.
But until now, it hasn’t been economical at scale.
GRAVELMIX changes that..
Producing RAC is complicated. Until now.
The pressure on the construction industry to deliver credible sustainability solutions is enormous – and using Recycled Aggregate Concrete consistently is one of the most effective ways to conserve resources at scale.
But there’s a catch: Making RAC requires so much additional effort that most plants only produce it in small volumes – if at all.
The pain point for concrete producers
For many ready-mix plants, RAC means operational friction.
Recycled aggregates typically require additional silo bins at the concrete plant.
Freeing up bins for one-off orders takes time, disrupts production planning and reduces throughput.
Plant conversions are expensive.
Or simply not feasible.
CIRCULAR ECONOMY

is a new, patented process that makes producing RAC simple.
Efficient and cost-effective.

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.
At the plant, the natural aggregate and recycled material are together washed and screened.
The solution is as simple as it is smart
The structural issue is tackled where it starts,
in the production process.
What if you could produce Recycled Aggregate Concrete (RAC) without production interruptions, juggling silo bins and without costly plant modifications.

The result
A fully pre-blended product with defined recycled content.
Concrete plants are supplied with these ready-to-use blends.
Even recycled sand that was previously difficult to use can now return to the value chain.

THE BIGGEST OPPORTUNITY ACROSS THE VALUE CHAIN
RAC saves enormous amounts of virgin raw materials.
GRAVELMIX makes it easy.
GRAVELMIX isn’t a future concept, it’s an industry-ready solution enabling a working circular economy in construction.
For demolition and recycling companies
GRAVELMIX enables higher-value utilization of mineral construction waste.
Recycled material becomes a sought-after raw material, and recycled sand can be fully returned to the material cycle.
KEY BENEFITS
For gravel and crushed-stone producers
GRAVELMIX creates a new revenue stream – and significantly extends the productive life of the site by conserving natural resources.
Recycled concrete has enormous growth potential, your plants remain competitive, and you increase your profitability.
For concrete producers
With GRAVELMIX, RAC concrete can be produced as a true drop-in – using existing plant infrastructure.
Simple to produce, economical and reliably available. No additional silo compartments, special logistics, production interruptions or modifications are required.

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.
