CORINTHI offers more than 100 tests for all types of construction materials. All tests are according to local and international standards and are carried out using the latest technology and equipment. CORINTHI also optimizes the test procedure by implementing state-of-the-art approaches which result in providing a wider, more comprehensive, interpretation of the material conditions. Along with CORINTHI’s state-of-the-art approaches, CORINTHI provides general recommendations that address possibilities of improving the quality of material; resulting, in a higher quality of project activities with less cost.
