  • cement coverings with a very high proportion of cement are susceptible to Shrinkage cracks. It is therefore important to make sure that the covering is in place when creating it is protected from direct sunlight and quick drying. Because of the Shrinkage behavior and the temperature-related expansion differences Cement coverings can only be produced in limited areas without joints. The production of cement floors is also expensive and their quality is not always that desired high level.
