Specialized in repair, maintenance, and rehabilitation of structures, such as bridges, tunnels, seaports, water structures, and public buildings.
The latest technology and methods of repair are implemented; all this comes along with full implementation of high standards of quality assurance, safety measures, and environment protection.
Examples of some of the problems dealt with :
- Cracks and deterioration of parts of the structural elements (columns, beams, slabs, walls…)
- Collapse of parts or all of the structural elements.
- Bad condition of bridges' steel bearings and expansion joints.
- Consolidation of earth layers at buildings or retaining walls.
- Concrete cover wearing.
- Reinforcement steel corrosion or damage.
- Deterioration and corrosion of steel sections and plates.
- Slabs surface protection to prevent abrasion and friction.
- Injection of cracks in tanks, buildings, etc.
- Isolation of concrete members beneath water level by using painting or applying sheets.
