Laboratory

The laboratory is an integral part of GIC's long-standing commitment to quality assurance.

The expert teams in our laboratories carry out numerous tests in the broader field of construction, both for internal quality control and for external clients. We conduct tests in multiple stationary laboratories across Slovenia, as well as directly on construction sites. All measurements and results are digitized, ensuring accessibility from anywhere at any time. One of our core values is integrity, which is why we record results using blockchain technology to ensure transparency and the immutability of the obtained data.
