Quality management

Company´s test laboratory

All products of HARTSTEINWERKE are of the highest quality – this is guartanteed by our own test lab.
Almost all bulk and asphalt mixtures are put to a variety of tests.

The rapid progress in the development of material technologies and the constantly changing requirements of the performance of building materials place higher and higher demands on their quality assurance.

Currently the in-house test laboratory is being modernised extensively.
