2. Geothermal should generally have expansion joints, with the maximum area not exceeding 30m. There must be expansion joints on the wall, and the lower parts of the four sides of the floor tiles must be ground at a 45-degree angle to prevent the floor tiles from loosening due to thermal expansion.

3. It is best to cover the geothermal pipeline with cushion first.

And then stay healthy,

After 7 days, if cracks are found in the cushion when paving the floor tile, please put 6 round steel bars, which will not crack easily, otherwise the floor tile will crack.
