Rock construction

JIITEE carries out rock construction in all kinds of conditions

Rock construction is common, especially in infrastructure projects that require sturdy foundations built into the rock. Mining and excavation projects are another example of cases where expertise in rock construction plays a decisive role. In rock construction, it is crucial to ensure the durability and safety of structures, as poor rock construction can lead to serious consequences. Well-done rock construction requires skilled personnel and the appropriate equipment.

We are accustomed to working in conditions that pose special requirements. In rock construction, demanding conditions include building at a height, in confined spaces, and in urban areas. Rock construction in demanding conditions is our passion, and we excel at devising innovative solutions for even the most challenging situations.

Rock construction can involve various tasks, such as tunnel excavation, grouting, rock drilling, and rock bolting. Thanks to our equipment and skilled personnel, we are ready to launch projects even at a short notice and can meet all of our customer’s rock construction needs.
