Concrete Installation & Repair Services

Placing concrete underwater is a challenging operation due to the logistics of supply, accessibility to the site and poor visibility in the underwater placement area. Qanbar Ready Mix has successfully supplied concrete underwater overcoming these difficulties with a combination of expertise and equipment.

Foamed concrete is typically made by mixing water, cement, and foam. It contains fewer chemicals and is a non-toxic, more environmentally friendly, and lightweight alternative to standard poured concrete. Its high air content and fire-resistant properties make it ideal for insulation, soundproofing, and filling those awkward gaps—old or unused pipes or spaces between bricks, for example. It is also used for structural elements, such as walls and floor slabs, and for interior buildings that aim to be more environmentally friendly.

Soil grouting is one essential activity of soil treatment where slump under slabs are treated, villa yards, soil enhancement in coastal areas, filling cavities, which might arise under footings during cavity detection process in addition to soil grouting of buildings before construction. The process includes drilling of several of boreholes at certain and specified depths and diameters then grout the cement mortar under specific pressure and in some cases, adding of chemicals to increase concrete strength. Grouting is continued until cavities are completely full filled and in turn, we attain grouted are free of cavities soil.

As a result of the presence of moisture, water leakage and acids, this affects the concrete and the steel reinforcement. Thus, it might create cracks and steel rust and, in some cases, (if not repaired), reinforcement will reach to complete corrosion, which cause sudden collapse of the structural elements. It is necessary not to ignore such cases, and find the drastic remedy. Concrete and reinforcement technique can be applied through a specific technical method where damaged portions are rehabilitated. This section cannot be identified as with one case, each structural elements and problem vary regarding repair volume and rectification, some methods like enlargement structural element sections, concrete patching, epoxy injection, and etc as applicable technically to attain drastic repair and rehabilitation.

Structural rehabilitation of concrete structures represents an important aspect of engineering and construction. The need to rehabilitate facilities may be necessary at any time from the beginning of construction until the end-of-service phase of the building. The need for rehabilitation during construction phase may have occurred due to fail in design, reduced concrete resistance or poor implementation. On the other hand, the need for rehabilitation during the service period refer to earthquake or the occurrence of accidents in the concrete structure such as collisions, fires and explosions. In these cases, we use the design process to support and strengthen the structural elements of the building using methods of dealing with situation of building, one of these method is enlargement the concrete section of concrete element and that will be using concrete jacketing method, or we use modern techniques such as supporting the concrete elements using Carbon Fiber Reinforced Polymer CFRP system.
