Fugues are crucial components of a building and play an important role in the stability, tightness and durability of concrete and soil surfaces. They ensure the necessary flexibility in the construction construction and equal voltages that arise from temperature fluctuations or load changes. Through environmental and mechanical loads, joints can become leaky or cracked over time. A regular review and maintenance of joints are particularly essential in areas with high stress, such as parking garages or industrial plants. Professional joint renovation is therefore essential to avoid consequential damage such as moisture occurrence, corrosion or crack formation and to ensure the security and the value preservation of the building in the long term.
