Do you do waterproof in the bathroom before doing underfloor heating?

Do you do waterproof in the bathroom before doing underfloor heating?Floor heating is waterproofed once before, waterproofed once after backfilling, a must. Otherwise, it will be very troublesome to have problems in the later stage

The state stipulates that the toilet must be waterproof, because the bathroom often needs water, that is, there is often water underground, if it is not waterproofed, the water will leak downstairs, so the state mandates that developers must do waterproof when building houses. The international standard stipulated by the State Construction Committee is meters, and the house has been waterproofed when it is built, and the waterproof layer extends from the ground to the wall, which is 220mm higher than the wall, but the waterproofing of the wall is basically not. According to the conventional bathroom, the height of the waterproof layer on the wall of the shower head shall not be less than 180mm, and the general thickness shall not be less, and the water storage test must be done for 24 hours after the waterproofing is completed.

Usually waterproofing is carried out before doing underfloor heating, and it is generally enough to paint twice. However, in the construction of the waterproof layer that has been done, we must pay attention to protecting this waterproof layer. I hope you find this answer helpful.
