Reinforced concrete is the most important construction material of our times. However, carbon dioxide and sulphur dioxide affect alkaline concrete protection and facilitate moisture penetration.
Corrosion-susceptible steel in the concrete expands leading to chipping of the surface and hazardous cracks. Damaged concrete parts of reduced load capacity may collapse, so they should be repaired.

Concrete reconstructed with epoxy resin as protection against corrosion
To maintain stability of reinforced concrete structures, damaged components must be repaired as soon as possible. However, first the cause of damage must be thoroughly analysed by a professional company.
Second, all loose concrete is removed, the surface is cleaned, and rust is removed from reinforcement. Then the affected metal is treated with an anti-corrosion agent. After these operations, in subsequent steps the concrete components are restored to their initial condition. Edges are profiled, and wherever necessary, cracks are closed by force and pressed.
For permanent protection of reinforced concrete structure against new damaging agents, all concrete surfaces restored to their proper condition are covered with a protective coating resistant to wear and tear as well as weather conditions, available in any colour.
This coating is resistant to chemicals, frost, salt used on roads in winter, as well as highly resistant to the highest loads and vapour-permeable.
Renovation of concrete external surface can be combined with further energy-saving operations, including thermal insulation and improvement in the constructional fire protection.
