Laboratories

We have more than 25 Specialized Labs distributed around the kingdom: at Jeddah, Yanbu, Madinah, Arar, Hafer Al-Baten, Sudaid, etc. we built such labs to complement our Quality Control Management, all labs have an advanced testing equipment and tools, no material proceed to site unless tested, all other construction materials are also tested after constructed like Concrete Members.

We have a trained staff and specialized department that take care of all of our Laboratories, this include purchasing Lab-Equipment, Testing, Calibration, and Maintaining such equipment in accurate and operational mode.



We also have special department that takes care of 3rd Parties Laboratories, including selecting, visiting, testing, and assessing such 3rd-parties-lab capacities and capabilities before approving them.
