why does the terrazzo floor have cracks? how should we avoid it?
nowadays, many families choose terrazzo as the floor. but some terrazzo will have cracks. why? how should we prevent it? let's take a look together!
reasons for cracks in terrazzo floor:
1、 the cast-in-place terrazzo floor has cracks, which are mainly caused by uneven ground surface or poor filling; incomplete filling of joints; another issue is that the foundation brick wall is built too high, resulting in uneven or too thin cushion layer thickness and causing cracks. 
2、 there are cracks in the terrazzo of the floor, mostly because of the tight construction period and unstable structure; the process of the cushion layer and surface layer is closely followed, the shrinkage of the cushion material is unstable, the buried pipeline is too high, and the surrounding mortar is not evenly fixed, causing cracks to appear. 
3、 cracks appear on the cast-in-place terrazzo floor, which are caused by unclean base cleaning, insufficient integrity and rigidity of the floor, and cracks when the ground load is too concentrated.
targeted crack prevention measures:
1. when backfilling the ground, the soil should be evenly filled and compacted, and should not contain debris or lumps. 
2. for the height of the foundation brick wall, it is not allowed to exceed the lower skin of the concrete cushion layer, and the thickness of the concrete cushion layer should be maintained. 
3. the cast-in-place terrazzo ground should have a certain curing period in the later period, so that it can be constructed after the completion of shrinkage. for floors with large loads, reinforcement should be added to the concrete cushion to increase the integrity and stiffness of the cushion.

the above is about the causes of cracks and their preventive measures. if you have any more information you would like to know, welcome to inquire!
