Background introduction

The bathroom is the area where most water is used for household use. If there is water on the ground frequently, the water will easily flow into the wall through the cracks in the wall, resulting in leakage. Once the drainage pipe is blocked at the leakage site, the water will easily leak down through the cement layer.

Once the toilet leaks, it will waste more money, manpower and time to rework or repair, knock down the floor tiles to find the water pipe in the cement layer, check the causes of the leakage, and then repair, and then re-install floor tiles, which will bring many inconveniences to the owners' lives.

If the toilet leaks, it will affect the lives of downstairs neighbors, and bring impact and inconvenience to the lives of neighbors.

If the leakage is serious and the downstairs decoration is damaged, compensation should be made to cause unnecessary economic losses. In order to avoid the above phenomena, we should do a good job of waterproof treatment in decorating kitchens and bathrooms, to prevent accidents in the future.

Key parts of waterproofing

According to the structural characteristics of toilets and showers, the key parts of waterproofing are:

1. Waterproof of large surface of concrete structural slab, including walls and floors.

2. The ports of pipes, nozzles and drains.

3. Ground and wall junction, indoor and door frame junction.

Waterproof treatment measures

According to the analysis of key waterproofing parts in toilets and showers, the waterproofing treatment is carried out.

1. Waterproof of large surface of concrete structural slab

According to the project situation, waterproofing materials such as polyurethane, JS and so on can be used to construct according to the design thickness. Before construction, it is necessary to ensure that the base meets the basic requirements of material construction. Before the surface construction, the joint parts such as the pipe mouth must be strengthened. The reinforcement layer of the coating should be matrix, and the tensile and crack resistance of the waterproof reinforcement layer should be strengthened. The construction scheme can adopt the methods of painting, rolling and spraying. At the same time, attention should be paid to the effect of subsequent tiles on the waterproof layer.

2. Pipe orifices and nozzle locations

Detailed parts must be strengthened first, and key points should be dealt with in large-scale construction. Drainage intake pipes and drainage outlets must strictly comply with the design requirements, and adopt flexible and rigid waterproofing treatment methods combining different materials with concrete to achieve sealing and waterproofing effect.

3. Ground and wall joints, indoor and doorframe joints

According to the project situation, the joint parts need to be handled. The floor must be 300 mm outward, and the door frame must be turned outward to the port for waterproof treatment.

Attention

During construction, if waterproof foundation treatment has been done, the original waterproof layer should not be destroyed during secondary waterproofing.

Waterproofing materials must conform to the relevant national standards, and have the corresponding test reports, factory certificates and other information.

During construction, professional construction plan and professional construction team must be established.

After the completion of the construction, the protection shall be carried out according to the requirements, and the waterproof and water closure test shall be carried out. The construction of the next working procedure shall be carried out only after the acceptance is qualified.
