The toilet in my house leaked, and the house was moved in in 2007, and it was leaking at that time,

In your case, the redone waterproofing is estimated to be of poor quality, which may be caused by the use of problematic materials or construction problems. Article 7 of the "Measures for the Quality Warranty of Housing Construction Projects" clearly stipulates that the developer's maintenance responsibility for waterproof and leakage prevention is five years, and within the five-year range, you can ask the developer to repair again, but for your last maintenance, your developer does not seem to attach importance to waterproofing, and it is recommended that you can negotiate with the developer to supervise the purchase of waterproof materials and participate in the supervision of the waterproof construction process, and choose a negotiated price for the cost. This is the solution to the problem completely, and we must pay attention to waterproofing again.

To redo the waterproofing, it is necessary to completely shovel off the previous one and do a good job of waterproofing the base. Sturdy, clean and flat. Then paint the waterproof coating, the waterproof coating is painted with two layers, the first layer is dry and solid, and then the second layer is painted, the thickness of the two layers is not more than 2mm, and the closed water test inspection is done after it is done.

It is recommended to choose good brand waterproof materials, such as Leibangshi and JCDecaux, these first-line brand products, the first quality is absolutely fine, and the second is that the construction is relatively perfect. It is equipped with detailed construction instructions and construction guidance, and the construction is convenient and simple. Water leakage is very troublesome, and when you do it again, you must be careful and properly supervised, and hope that you will completely solve the water leakage problem at home as soon as possible.

First of all, you must have not done a good job of waterproofing, and you need to do waterproofing again. At present, the cement-based waterproof coating used in the household is OK, such as the general-purpose waterproofing slurry of Leibangshi.

Secondly, you can find the housing quality inspection department for testing, and then take the report to the court to ask for a decision.

Waterproof products have a lifespan, if rigid waterproofing, there will be leakage in a few years, it is recommended to use long-life elastic waterproofing.

Regardless of the upper and lower floors, the developer should be responsible, or you have to find the developer to study the repair problem.

If you don't know, don't talk nonsense.

Flexible life is shorter.

Besides, it is not clear what the water seepage is in his house.

What is the leak?

How did the developer do it when it was redone.

Is it that the current leakage is the same as the original leakage?
