Generally speaking, there are more phenomena in the use of the floor in the form of tiles or arches. This is because the floor is damp. The reasons for the dampness of the floor are as follows: (1) Moisture in the air (for example, Huangmeitian). (2) The floor is not dry, and the keel is reinforced with cement. (3) The keel, the floor is too wet. (4) Use water-based glue. (5) The damp environment such as the first floor is not specially treated for moisture. (6) The section where the stone floor and the floor meet are not closed. (7) Blisters (such as water pipes rupture, balcony water reflow, etc.). In addition, the product itself and improper construction will also cause arching. For example, improper drying treatment, inadequate health, low water content, shallow back groove, insufficient expansion gap in construction, and too tight laying.
