50 years for cement brick and 70 years for red brick. The service life of cement brick is mainly determined by the manufacturing materials of cement brick, the maintenance and quality of brick materials, the use mode of cement brick and the environment. The probation period of cement brick stipulated in the building is 50 years.

If you want to choose high-quality and durable bricks, red bricks are the best choice, and the service life of decades is absolutely no problem.
