Repair mixtures for concrete structures and buildings
Concrete structures are exposed to various factors during operation, which lead to different types of damage and cracks. Even during the construction of new structures, in case of violation of construction technologies or for other reasons, situations may arise when concrete repairs are required. After all, if it is not carried out, then small cracks and chips can develop into large-scale damage or collapse of structures.
To solve these problems, special concrete compositions have been developed, which differ in their composition and scope of application. They can consist of many components and have special properties.
Teknogrout EX injection molding repair compounds are designed to repair damaged horizontal surfaces, they fill specially prepared cracks and recesses. They have a high rate of adhesion to concrete, stone and reinforcing frame and do not shrink. The solution evenly fills and reliably seals the free space, strengthening the surface to be repaired. Allows to produce a filling layer from 10 to 60 mm.
The use of such a composition is perfect for:
- concrete works of aircraft landing strips, railway tracks and large-scale engineering structures and structures
- installation of industrial equipment, metal columns, pillars and wells
- repair of sections of connection of reinforced concrete products with beams
- reconstruction of buildings and other facilities
Teknorep 300 and Teknorep 300 EX thixotropic repair compounds are excellent for both horizontal and vertical surfaces and do not shrink. These mixtures are reinforced with polymer fibers to increase compressive and flexural strength.
The use of these formulations makes it possible to eliminate defects with a thickness of 10 to 40 mm, and is used for:
- repair of concrete products and structures in all types of engineering structures
- repair of concrete products after removal of formwork systems
- filling holes from fittings and coupling screws
- repair of prefabricated elements made of reinforced concrete
The repair compounds discussed above are resistant to freezing and thawing, are resistant to chemicals and do not cause corrosion of metal elements. Depending on the components, they can quickly adhere to the surface. For example, Teknogrout EX has a curing time of 2 hours, which can be a huge advantage for urgent and quick repairs. Compliance with the instructions and recommendations of manufacturers will allow you to carry out effective and high-quality repairs of concrete structures and buildings.
