The bathroom was slotted, the waterproof layer was destroyed, and then the floor heating was paved,

Bathroom waterproof construction technology, process and precautions Before the bathroom decoration construction, we must first determine the design of the water circuit, and we must consider the possibility, feasibility and availability of the design scheme in detail. Lay the water, electricity and heating pipes first, and then level. When doing waterproof construction in the bathroom, the base layer should be treated first.

Remove the original decoration materials, clean up the floating soil and cement, first use cement mortar to level the ground, and then do waterproof treatment, requiring a smooth and dry surface. This avoids leakage of the waterproofing coating due to uneven thickness. When paving the waterproof coating, it should be evenly painted, and there should be no missing brush, bulging and falling off, and the thickness of the waterproof coating layer should not be less than, otherwise it will affect the waterproof effect.

During construction, pay attention to the waterproof dead corners, the joints between the wall and the ground, and the joints between the water and water pipes and the ground, which are the most prone to problems. After the construction of the waterproof layer in the bathroom, block all the sewers in the bathroom, build a 25cm high barrier at the door, and then pour 20cm high water into the bathroom. After 24 hours, check whether there is leakage on the surrounding walls and ground, if there is leakage, it needs to be repaired in time, and then do a 24-hour water test without leakage before entering the next stage of construction.

After the completion of the water shielding test, it usually takes 5-7 days (it takes 5 to 7 days for the waterproof coating to form a waterproof membrane), and then make a layer of cement mortar protective layer on the waterproof coating layer, one to protect the waterproof coating layer, and the other is convenient for veneer bricks, pay attention not to destroy the waterproof coating layer that has been done.

The bathroom is equipped with underfloor heating, which also needs to be waterproof. Nowadays, the general bathroom has caissons, so in general, it needs to be waterproofed three times.

The first time is that a waterproof is required before backfilling, and this layer also needs to be tested for closed water.

Secondly, the second layer is the ground backfill, and a layer of waterproofing needs to be done after leveling.

The last layer is to do waterproofing again after installing floor heating, and this layer also needs to do a closed water test.

But this is mainly for you to install plumbing, if it is electric heating, then the layer after leveling can also be optional.

It should be done on the bottom floor of the underfloor to put water on the side.
