Paving tile cracking means that paving tiles show small cracks on the glazed surface after being paved for a period of time, and can enter dyeing liquids such as ink. This disadvantage is easily exhibited when the operating environment is relatively humid. What are the causes of cracks in paving slabs?

1.There is a problem with the inherent quality of paving slabs

If the crack resistance of the brick does not meet the requirements of the specification, after paving in a humid environment for a period of time, the glaze cracks will be caused by the internal stress. The cracks caused by this cause are more uniform and not necessarily distributed. In different areas, different rooms, and different buildings, you only need to use the same or similar conditions, and the probability of cracks is the same.

2. Reasons for construction

Prefabricated structures, mortar mixes, and methods of paving often cause cracks in the later stages. If the room is buried with dark lines and the depth of the buried lines is too shallow, it may cause cracks on a line. There are wooden components under the foundation. It may also show neatly shaped cracks. If the same batch of bricks are paved by different workers in different rooms, the operating environment is basically the same. One room is intact and the other room has cracks. If the prefabrication is ruled out together, The structural reason is most likely related to the proportion of the mortar and the method of paving.
