Concrete renovation - what can you do against damage & dirt?

Concrete is considered an indestructible and robust material. Nevertheless, it can get dirty after a relatively short time. If the first damage appears, it can indicate defects in the concrete structure. Cracks and chipped areas often indicate that there is major damage hidden behind them, which can only be repaired by renovating the concrete. There are a number of reasons for such deficiencies: They range from improper work in planning, mistakes in implementation Work up to weathering. Here we show you how you can recognize the deficiencies in facade construction and successfully carry out a concrete renovation.
 

Concrete is a natural building material

Concrete is a natural product: during its manufacture, cement is mixed with gravel or sand and water. If structural steel or prestressing steel is added, it becomes reinforced concrete. However, the main component of concrete is always the cement, it is the link that connects the grains of gravel or sand with one another and turns them into hard rock. It protects against fire, keeps out noise and moisture and has a heat-insulating effect. Because concrete is a natural building material, it is considered a sustainable building material with a good ecological balance. Because the costs of producing concrete structures are relatively low, concrete is an economical building material.
 

A concrete wall has to do all that

A wall made of concrete insulates against cold and heat, withstands fire, protects against noise and withstands almost any pressure. Therefore, concrete walls in modern buildings not only form the outer shell of the house, but are also used inside to divide the rooms. The liquid concrete is poured into the formwork and the surface of the rough-sawn boards is clearly visible after it has hardened. That concrete wall remains unplastered, the concrete is exposed concrete. The material has been used in architecture for over a century, a sober, minimalist and modern building material that even allows free and moving forms. If a steel grid is built into the concrete, the wall built with it is pressure-resistant and can carry heavy loads. Other properties of a reinforced concrete wall:
 

• impermeable to water
• insulates sound very well
• insulates the heat rather poorly
• is sometimes prone to cracking
