Laboratory & Building Material Testing

LABORATORY AND TESTING CENTRE

Tested quality

No road surface would be durable, no material innovation sustainable without comprehensive quality control. It is the foundation for safe, economical and sustainable construction projects. To ensure this uncompromising standard, SWIETELSKY has its own accredited testing and inspection centre in Contela GmbH. It is the driving force behind our quality assurance and ensures that only tested and approved materials find their way onto our construction sites.

Comprehensive testing expertise from a single source

Using state-of-the-art methods and decades of experience, our team of experts tests all relevant materials. We ensure that legal requirements and standards are not only met, but often exceeded.

Asphalt and bitumen technology:
We carry out factory production control (FPC) for our asphalt mixing plants. In the laboratory, we develop and test new mix designs, test asphalt types with increased recycling content and evaluate the effectiveness of innovative additives.
Environmental chemistry:
As an independent body, we carry out chemical environmental analysis. This includes the analysis of construction waste in accordance with the Recycling Building Materials Ordinance, the examination of groundwater and wastewater, and the determination of the chloride content in hardened concrete.
Earthworks and aggregates:
We ensure the quality of unbound base courses, frost protection materials, sands and gravels. Compaction control after installation by means of load plate testing or density measurement guarantees the longevity and stability of the substructure.

More than just testing: the innovation driver for SWIETELSKY

We see our testing centre not only as a supervisory authority, but also as a driving force for the further development of the entire construction industry.

Development of sustainable building materials: We are actively committed to making building materials increasingly environmentally friendly. Together with the operational units, we thus create technical and economic added value.
Shaping standards: Through active participation in national and international standardisation committees, we are shaping the quality standards of the future.
Evaluation of innovations: We evaluate new materials and processes in order to identify sustainable and resource-saving solutions for our projects.

This in-depth, in-house expertise gives us the confidence to seamlessly control the quality of our projects and actively shape the development of the industry – day after day, construction site after construction site.
