The problem of water leakage in the bathroom is often caused by water seepage on the ground or damage to the upper and lower pipes. Before starting maintenance, we must first determine the cause of water leakage. After understanding the causes of water leakage, let's take a look at how the bathroom is waterproof.

Cause judgment: groundwater leakage

As long as there is water on the bathroom floor, there is water leakage downstairs. When there is no water on the ground, there is no water leakage downstairs.

Cause judgment: water pipe leaks.

This situation is usually large and persistent. You can detect whether there is a problem with the sewer pipe by pouring water into the floor drain, washbasin and toilet. If there is no water in the bathroom for several days, there is still water leakage and it has not been alleviated, then it is probably a problem with the water supply pipe.

Waterproof treatment: ground treatment

Make sure that the ground is flat before waterproofing. Uneven ground may lead to uneven thickness of waterproof coating, which may lead to cracking and leakage. It is recommended to use flexible waterproof coating with high elasticity at joints such as floor drain, corner and pipe root, because these places are most prone to displacement and water seepage.

Waterproof treatment: wall treatment

Wall waterproof coating should be applied to a height of about 30cm to prevent water infiltration. If the bathroom has a shower room, the waterproof should be180 cm; ; If there is a bathtub, the waterproof height of the wall adjacent to the bathtub should be 30cm higher than that of the bathtub.

Waterproof treatment: maintenance of waterproof layer

After the waterproof layer is completed, give it a certain curing time to ensure its perfect integration with the building. Then add a protective layer on the waterproof layer before laying floor tiles. In the process of construction, attention must be paid to avoid damaging the waterproof layer.

Waterproof treatment: waterproof material for joint repair.

If the floor tile has been laid, don't smash it. At this point, you can use professional waterproof materials to plug all the gaps and do a good job of waterproofing. This is also applicable to the waterproof project after the waterproof layer of the bathroom fails.

Waterproof treatment: system engineering

Waterproofing is a systematic project, and the reasons and treatment methods are different in every place. Materials are the foundation, construction is the key and follow-up service is the guarantee.
