Stone and gravel for construction expertise
Stone and gravel are among the most essential building materials in the construction industry. They provide load-bearing capacity, stability, frost resistance and drainage, and serve as aggregate components in concrete and asphalt production. As a result, their range of applications is extensive: they are used in civil engineering (foundations, roads, pipeline construction), building construction (ceilings, columns, walls), residential construction (floor slabs, cellars, outdoor areas), gardening and landscaping (pathways, retaining walls, gabions), industrial sites (factory floors, logistics areas), railway lines (track bed, sub-base), hydraulic engineering (bank and embankment protection) and flood protection systems (dams, protective structures). Given their critical role, it is all the more important that the quality, availability and procurement of gravel and stone for construction projects are as straightforward and reliable as possible.
What to look out for when buying stones and gravel
The wider the range of applications, the more important it becomes to have clearly defined product ranges, standard-compliant grain sizes, fast delivery routes and straightforward advice from the right points of contact. Today, anyone looking to purchase stone and gravel is not just looking for materials, but:
- a reliable supply, even for large or fluctuating volume requirements
- proximity within the region, to reduce transport costs and CO₂ emissions
- predictable pricing and material availability
- sustainable solutions
- clear and responsive points of contact
This is exactly where we come in: roxit supports construction and infrastructure projects with high-quality, locally sourced raw materials backed by expert guidance and tailored to each specific project – reliable, standard-compliant and sustainable throughout the entire construction process.
The challenges we help solve
Today’s construction, infrastructure and industrial construction projects face a growing range of challenges. Material quality can fluctuate, delivery delays can bring work to a standstill, and public-sector clients increasingly require strict compliance with standards and sustainability requirements. At the same time, project teams are under constant pressure to meet tight schedules and control costs. Civil engineering and traffic route construction projects, in particular, frequently require large volumes of materials over extended periods, often with peak loads or short-term surges in demand. The raw materials and building materials industry, for its part, depends on a reliable supply of intermediate products, while recycling and waste management companies require proof of quality and regulatory clarity. Public contracting authorities expect transparent documentation and certified quality, industrial and commercial buildings require stable sub-bases, and environmental and landfill projects are subject to strict requirements regarding land reclamation and material acceptance.

Recycling and waste management
Our sites operate facilities approved by the relevant authorities for:
- Acceptance and processing of excavated material
- Processing of construction and demolition waste (e.g. concrete rubble)
- Monitoring in accordance with waste management regulations
- Separate collection of hazardous and non-hazardous waste
These authorisations ensure legally compliant processes and enable closed-loop regional material cycles.
CE marking and factory production control (FPC)
To ensure supply capacity in the building construction, civil engineering and traffic route construction sectors, compliance with standards, along with supporting certifications and documentation, are essential. We meet these requirements at all sites where aggregates are manufactured or supplied. This includes:
- CE marking in accordance with the Construction Products Regulation (EU 305/2011)
- Factory production control (FPC) in accordance with:
- EN 12620 – aggregates for concrete
- EN 13043 – aggregates for asphalt
- EN 13242 – aggregates for unbound and hydraulically bound materials
These certifications are a fundamental requirement for supplying concrete plants, asphalt plants and infrastructure and traffic route construction projects, and are therefore part of our standard practice. In Poland, we also hold Factory Production Control (FPC) certification under System 2+, which fully meets European regulatory requirements.
Sustainability at roxit
Sustainability is an integral part of how we work. We source raw materials responsibly, focus on resource-efficient extraction planning and consistently incorporate recycled building materials into real-world construction and infrastructure projects. At the Kanzelsteinbruch quarry in Gratkorn, roxit is testing a hydrogen-powered wheel loader to further advance low-emission drive technologies for heavy construction machinery. By processing concrete rubble, asphalt rubble and excavated soil, we close regional material loops and reduce the use of primary raw materials. This allows us to support our clients in meeting their ESG, procurement and climate targets, from low-carbon building materials to verifiable recycling rates. For more information about sustainability and how we support you in this respect, see here.
