Quality begins with the inspection - and we do this in-house.
We carry out comprehensive tests on gravel, asphalt and concrete in our in-house laboratory. This in-house production control is specially designed for our construction sites and helps us to ensure the highest quality and reliability.
Whether grain size distribution in gravel, binder content in asphalt or fresh concrete tests on the construction site - the Kostmann team keeps an eye on the relevant parameters at all times. We are constantly undergoing further training and remain at the cutting edge of technology through our active participation in standardization committees.
The result: high-quality materials, reliable processes and a good feeling on every one of our construction sites.
